Apollo 400 Watt Power Supply for the ADAM Computer Memory Console 

 

 *** Limited run of only 26 power supplies outfitted with a custom Coleco ADAM wiring harness ***

 

Athena Power has created the Apollo 400 Watt Switching Power Supply model number AP-MP4ATX40 which has the rare -5 volts DC feature (-5 volts DC feature has been discontinued from all or most ATX power supplies on the market). This Apollo 400 Watt Power Supply model AP-MP4ATX40 has been outfitted with a custom wiring harness that is for use with the Coleco ADAM Computer Memory Console and the Coleco ADAM Printer. This high-end 400 Watt Coleco ADAM Memory Console Power Supply has plenty of power to power just about anything that is released in the future for the ADAM computer.

 

In the 80’s and early 90’s I use to use the original Coleco ADAM power supply to power my ADAM computer 24 x 7 for several years, until I switched to a third party power supply for the ADAM computer.

 

It is recommended that the Apollo 400 Watt Power Supply be connected to a UPS system (Uninterruptable Power Supply) or a high quality surge protector to increase the lifespan of your ADAM computer and Apollo 400 Watt Power Supply. This power supply is designed to run 24 x 7 for several years on the Coleco ADAM computer system. Computers last longer when turned on and ran 24 x 7 at a constant temperature. The MTBF (Mean Time Between Failures) rating on this power supply is 100,000 hours. Which means this power supply when connected to a good quality UPS or surge protector has the potential to last over 10 years. The Apollo 400 Watt Power Supply has a 1 year repair or replacement warranty.

 

This Apollo 400 Watt ADAM Computer Memory Console Power Supply is designed to operate anywhere in the world between 88-264 volts and between 47-63Hz (somewhere between 100-240 volts at 50/60Hz is common). One just connects the style of power cord they need and flips the input voltage switch on the Apollo power supply to either 115 volts or 230 volts. There is also an on/off power switch on the power supply that makes it easy for ADAM owners to turn their computer system on and off. When the power supply is on and running there are two very low noise fans that run to keep the power supply cool (the fans are automatic variable speed based on the internal temperature of the power supply). There is one fan in the front and one fan on the rear of the power supply.

 

This Apollo 400 Watt Power Supply for the ADAM computer was designed to operate in room temperatures between 0 degrees Celsius to 50 degrees Celsius (between 32 degrees Fahrenheit to 122 degrees Fahrenheit). Power supply storage and shipping temperature is between -20 degrees Celsius and +80 degrees Celsius (between -4 degrees Fahrenheit to +176 degrees Fahrenheit).

 

The Apollo AP-MP4ATX40 has received several safety certifications and/or approvals: FCC certified for Home and Office, cUL, UL, TUV, CB, and CE.

 

*** Disclaimer *** This Power Supply uses a high quality original Coleco UL listed 5.5 feet DB9 power cable and other high quality UL approved material to interface the Coleco ADAM wire harness to the Power Supply. However, this Coleco ADAM Power Supply wire harness was only UL listed and UL tested on the original 1983 Coleco ADAM power supply and has not been UL listed and UL tested when connected to the Apollo AP-MP4ATX40 power supply.  

 

 

More information about the limited run of 26 Apollo Power Supplies with a Coleco ADAM wire harness installed

 

 

The reason why there was only 26 of these high-end ADAM computer power supplies made, is because I was only able to purchase a maximum of 26 original Coleco ADAM UL listed DB9 power cords. These high-end Coleco power cords are no longer made. In my communications with Athena Power in the future it might be possible for them to make a Coleco ADAM compatible power cable that matches or beats the original 1983 Coleco ADAM power cord quality. However, there is a strong possibility that any future custom power supply with an ADAM wire harness pre-installed well require a minimum order of 300 or possible 500 power supplies directly from Athena Powers Chinese factory. I am looking into the possibility of a custom Coleco ADAM compatible wire harness being installed at Athena Powers USA offices at a much lower QTY then 500. Therefore, there is a possibility that these 26 Apollo Power Supplies might end up being the last official third party power supplies made for the Coleco ADAM computer since no one makes a DB9 power cord anymore, and to get UL quality Coleco ADAM compatible DB9 power cords made up it might mean a minimum order of 500. Also like all other prior ATX power supplies on the market with -5 volts DC, the Apollo AP-MP4ATX40 might soon be going out of production (or might possible already be out of production once inventory is depleted).

 

This ADAM Memory Console Power Supply also allows one to connect their original Coleco ADAM Printer over an ADAMNET DB9 connection. Connected to the ADAM Power Supply is a high quality 100% foil shielded 28 gauge DB9 cable that is labeled “PRINTER”. This DB9 printer cable has 9 Gold Plated pins (cord length around 2.5 feet). This Apollo Power Supply for the ADAM computer only powers the ADAM Memory Console and well not power the ADAM printer. Before using the ADAM printer one needs to turn the power on the printer and then pull the Memory Console reset so that ADAMNET sees the Coleco ADAM printer attached. One very nice feature of this ADAM Memory Console Power Supply is that it removes the bug where the ADAM printer carriage return advances one space when the computer Memory Console reset is pulled. Normally what would happen is that when the ADAM printer was powering the ADAM computer, the paper in the printer would advance one line each time the computer Memory Console was reset. This resulted in the paper being ejected from the ADAM printer after several Memory Console resets. This bug is fixed with the ADAM printer no longer advancing the paper in the printer one line when the ADAM Memory Console is reset. In addition, the ADAM printer runs cooler since now the printer power supply only powers the actual printer and not the entire ADAM Memory Console. The power to the printer only needs to be turned on when one actually plans on printing.    

 

As a bonus a 2 Port ADAMNET HUB with 7 feet connection cable is included when one purchase this 400 Watt ADAM Power Supply. Suggested retail list price on this custom 400 Watt ADAM Power Supply is $129.99 plus shipping.

It's nice to see a source for Adam Power Supplies, but the price for a converted PC Power Supply is exorbitant. There have been others in the past that have sold such units for considerably less... ArcadeCollecting was one such person. Yes, I know, he didn't use a repurposed Adam power/Adamnet cord or include a printer hookup... but still.

How much for just the 'ADAM Computer Memory Console Power Supply' sticker? 

I never thought about making these ADAM Memory Console Power Supply stickers available to anyone else except Athena Power (However if you wanted to make your own power supply and wanted to use this sticker I could sale just the sticker). These are high quality top of the line stickers that use a Full Color, 4 color process made out of waterproof Vinyl and require a minimum order of 25 from the company that prints the stickers. I currently have 6 spare stickers in stock. If anyone wants to purchase this sticker for their custom made ATX style power supply, then send me a private message requesting a PAYPAL invoice for $5.25 which would include shipping and handling.

It's nice to see a source for Adam Power Supplies, but the price for a converted PC Power Supply is exorbitant. There have been others in the past that have sold such units for considerably less... ArcadeCollecting was one such person. Yes, I know, he didn't use a repurposed Adam power/Adamnet cord or include a printer hookup... but still.

 

The Apollo 400 Watt Power Supply for the ADAM Computer Memory Console is a top of the line power supply using the best quality material, which is one reason that the price is higher (It’s also the only 400 Watt Power Supply on the market for the ADAM Computer).

 

Yes, the Apollo 400 Watt Power Supply for $129.99 costs $30 more when compared to the $99 ADAM Power Supply that Milli Vee plans on releasing sometime in September 2018. In addition, the advantage of Milli Vee’s power supply is that it has a built in ADAMNET ports on the power supply itself plus a neat looking plastic case (some people prefer metal cases over plastic when it comes to high voltage power supplies). However, that Mean Well RT-50 watt power supply that Milli Vee is using has an online price of around $15. The Mean Well RT-50 Watt power supply that Milli Vee is using needs additional parts and labor to get it to work on the Coleco ADAM computer system and that is why the list price is $99 for his power supply design. Athena Powers Apollo 400 Watt Power Supply AP-MP4ATX40 can be found for around $35 which is more then double the price of the $15 Mean Well RT-50 power supply. In addition the Apollo 400 Watt power supply needs a Coleco ADAM wire harness to be purchased along with other high quality parts, plus a few hours labor removing the ATX wire harness and installing the official Coleco wire harness (plus the purchase of special tools to get the job done right).

 

Some might say that 400 Watts of power is over kill for the ADAM computer, however many brands and models of power supplies on the market when they get to be over 10 years old, sometimes start losing their full output capacity. If one starts at 400 watts and in 20 or 30 years later if the power supply is still working, maybe the power supply is only capable of putting out 200 watts. However, even 200 watts is plenty of power for just about anything connected to the ADAM computer.

 

The EBAY and Amazon fees raise the price on this power supply 20% to 25%. I do not have an official website to sale products on. However, if one were to contact me by private message, I would consider offering a 20% discount off the Apollo 400 Watt Power Supply for the ADAM Computer Memory Console if one were to pay with a money order. Or instead a 15% discount if one pays by PAYPAL directly. If contacted directly on the Amazon or EBAY interface, there would be no discount since the Amazon and EBAY rules require the sale to occur over their website interface.

 

Some information for those that want to install their own Coleco ADAM wire harness on their own Apollo 400 watt power supply

 

The 26 original 1983 Coleco ADAM DB9 power cords made this project a reality for the limited run. Now a Coleco ADAM compatible DB9 power cord needs to be developed. In the ideal world one should be able to order a 400 Watt ADAM Computer Power Supply directly from Athena Power with a custom Coleco ADAM compatible DB9 wire harness already pre-installed. Maybe that might be an option in the future. However it looks like a minimum order of 500 power supplies might be required if a Coleco ADAM compatible DB9 wire harness is developed by Athena Power’s Chinese engineers (Even though 500,000+ ADAM’s were made between 1983-1985, possible only around 5,000 people still use their ADAM computer for games, etc). So 500 ADAM power supplies might be way too many to meet exiting demands. If Athena Powers USA offices are able to install the Coleco ADAM compatible wire harness instead of the Chinese factory then maybe 50 official power supplies could be made, but the 300-500 number is a more realistic number to develop a full functional Coleco ADAM compatible DB9 power cable that matches or beats the existing quality.

 

Some parts that need to be ordered for those with the electronic skills to work on high voltage power supplies

 

This project would be a lot more easier if a fully modular ATX power supply existed with the -5 volts DC feature (If such a power supply existed, then the Coleco ADAM DB9 power cord could be plugged directly into a 24 pin ATX style module connector on the power supply without needing to open up the power supply). However the reality is no -5 volts DC fully modular ATX power supply was every released on the market. Also all or most ATX power supply companies have removed the -5 volts DC feature from all ATX power supplies being developed in 2018.

 

At one point in my email conversation with Athena Power, if I purchased a certain model of power supply they offered to install the 1983 Coleco ADAM DB9 power cord directly on their power supply if I shipped the original Coleco cords to them. When removing and installing a different wire harness one has the option to either solder the wires directly on the power supply or instead to use UL listed or UL approved crimp on connectors. Even though Athena Power and I have the skills to repair and modify things at the component level, a decision was made to not touch the original circuit board soldered components. The Apollo AP-MP4ATX40’s power supply was assembled using high quality robotic automation on the circuit board. Therefore, when the wire harness was installed, the original circuit board solder is exactly untouched and unmodified so that it would maintain all its safety certifications for the power supply section. The power supply uses both 18 gauge and 20 gauge wire for the actual power section of the wire harness. The quality electronic components used to install the Coleco ADAM DB9 wire harness to the power supply have amp and voltage ratings that far exceeding the quality of what is needed or required. Since there is many ways to modify or install a wire harness to a power supply I will not go into all the details of the components that were used for this project. Everyone might choose to connect the Coleco ADAM wire harness in a different way. Some people might spend 6+ hours de-soldering the wire harness from the circuit board and soldering the Coleco ADAM wire harness directly to the circuit board. On the other hand, some people might spend around 2.5 hours using high quality UL approved crimp on connectors and removing a massive amount of wires from the old wire harness without using any type of soldering iron. This Apollo Micro SFX power supply is very small compared to a full size ATX power supply (Nice cosmetic size but also harder to work on when the cover is removed). Some people might be twice as fast at converting a power supply to work with the ADAM since that type of work they do every day of their life. This project is for people that have the certifications and degrees to work on high voltage equipment. The power supply should be unplugged from the AC outlet before removing the power supply cover to prevent the possibility of being accidently electrocuted by touching the high voltage section of the power supply.

 

Some parts one might want to use

 

(The main part that is needed is the power supply with -5 volts DC). The best top of the line Desktop PC power supply on the market that has the -5 volts DC feature is the Athena Power Apollo 400 watt Power Supply model number AP-MP4ATX40. Amazon sales the retail box version of the AP-MP4ATX40 for $47.10 plus free shipping however a brand new AP-MP4ATX40 can be purchased in a OEM box for $34.98 plus free shipping from Outlet PC. And that $34.98 price is almost the same price that wholesale dealers purchase the AP-MPATX40 directly from Athena Power.

 

(The second most important part is to obtain the original Coleco ADAM DB9 power cords). Around 10 years ago I purchased around 25 Coleco ADAM DB9 Memory Console power cords from a ADAM dealer. That dealer no longer has the cords in stock and well most likely not be getting anymore. I believe I paid around $20 each for the original Coleco ADAM DB9 Memory Console cords. If one has an old Coleco ADAM printer or a Coleco ADAM printer power supply that no longer works, then one could remove the high quality Coleco DB9 UL listed power cord so that the cord can be installed on the Apollo 400 watt power supply. It is my understanding that in the year 2018 that no one makes a heavy duty Coleco ADAM DB9 compatible power cord anymore. So one needs to hunt for a broken Coleco ADAM Printer or Coleco ADAM printer power supply to make this project a reality.

 

(The third main component of this project is optional and is only required if one wants to still connect and use the original ADAM printer). A Gold plated DB9 28 gauge fully shielded cable can be purchased for $5.45 plus free shipping from Cables Online. One just cuts the female end off and wires the cable directly to the ADAMNET connection that is created inside the Power Supply. Some people for a few dollars cheaper might want to instead install a DB9 male connector on the outside of the power supply case. However, there are two issues with this. First issue is one needs to be skilled in drilling a hole through a metal case to install and mount the DB9 connector on the outside of the power supply. The second issue is with some testing I found that cosmetically plugging the Coleco ADAM printer cable directly into the side of the power supply case does not look good cosmetically. The better solution was to use the Cables Online $5.45 fully shielded gold plated cable that I mentioned above. It looks better cosmetically plus no need to spend time making a hole in a metal case to mount a DB9 jack. This cable is for very low voltage/current ADAMNET communication, the power supply built in the ADAM printer is still used to power the printer. The printer runs cooler since only the printer is being powered and the printer power supply no longer powers the ADAM computer.  

 

(The fourth main component of this project is to either solder the Coleco ADAM wire harness to the circuit board or to use high quality UL approved and/or UL listed crimp on connectors). When I had the wire harness connected I decided to use parts that are above and beyond the needed voltage and amp rating that is required. So one can easily calculate around $10+ for supplies for each power supply depending on how one decides to attach the wire harness. Also purchasing some type of rubber feet for the Apollo 400 Watt power supply is ideal to prevent the surface counter and bottom of the power supply from being scratched. Remember normally these power supplies are installed internally in a PC instead of being installed externally.    

 

Therefore, one is looking at a minimum of $70.45 including power supply and supplies to outfit this Apollo 400 Watt Power Supply so that it works with the ADAM computer. That is assuming that one has paid around $20 for the Coleco ADAM DB9 power cord. However, that price does not include the research and develop cost. Sometimes one runs into quality issues with supplies and materials and needs to switch to a different brand or style of connector (and purchase several samples of products to test their quality level). Another issue is I needed to purchase the proper tools to work on this project (some people might already own the proper tools). The wires that were stripped needed to be perfect quality with no missing strands, therefore a $74.45 Xcelite SAS3210 automatic 32 to 10 gauge wire stripper was used. This is the nicest automatic wire stripper that I have every used. In addition, I needed a SG Tool Aid SGT18980 crimping tool for around $100 for some of the UL listed connectors used in the project. This tool makes a perfect crimp every time that it is used.

 

Here is some important wiring information that one needs to know for this project

 

 This link has useful information regarding the ATX power supply wire colors and what voltage levels is assigned to the wires inside the power supply and the ATX 24 pin connector.

 

 

Here is the pinout information for the Coleco ADAM DB9 power cord.

 

 

Pin 1 = +12V brown
Pin 2 = +12V red
Pin 3 = +5V orange
Pin 4 = -5V yellow
Pin 5 = ground green

Pin 6, 7, 8 are used for ADAMNET communication with the printer, etc = serial data clock, serial data, signal ground.

Pin 9 = no connection

 

If my memory is correct only wire pins 5 and 7 on the DB9 male connector if using the ADAM Printer (not in front of my ADAM to verify and would have to take the power supply apart to check the wiring). When wiring the ADAMNET data connection correctly a bug that use to cause the ADAM printer to advance the carriage return one line space after pulling the memory console computer reset well no longer occur anymore.

 

Here is a link to the DB9 Male and DB9 Female pin out assignments. They are different pin outs depending if the connector is male or female.  

 

I hope this information is useful for those that are interested in converting a rare hard to find ATX power supply with the legacy -5 volts DC feature to work on their Coleco ADAM computer system.

Milli

I agree your plastic power supply case looks better when compared to the metal case used for the Apollo 400 watt power supply (but I like metal cases better when 120-220 volts input is involved). Your power supply project also has the neat feature of two ADAMNET ports being built into the plastic power supply case. When I did the wire harness I decided to only make the ADAMNET printer connection part of the power supply and the bonus ADAMNET hub is a separate device that plugs into the side or front ADAM Memory Console ADAMNET jack.  

 

When you release your power supply in September 2018 or later this year I might purchase one for $99. Its good to have a spare power supply to keep the ADAM computer working a few more decades.

Since the original Coleco DB9 power cords can not be purchased anymore. Here is one possible alternative:

 

While 18 gauge cable is better and the Coleco original cable is ideal. I did find a supplier online that is selling Gold plated 20 gauge shielded DB9 cables that are high quality. The problem is the price is $39.07 for 10 feet and $34.38 each when purchased in QTY’s of 25 or more. A person could cut the male end off the cable and wire it directly to the power supply and the female end would connect to the ADAM Memory Consoles male DB9 connector (but the Coleco one is unique and would fit better).

Also read the following post for possible other alternatives for a DB9 power cable substitute for the Coleco ADAM computer.

Apollo 400 Watt Power Supply for the ColecoVision

 

(Requires a ColecoVision wire harness to be installed)

 

 

This Apollo 400 Watt Power supply is 100% compatible with the ColecoVision system, however since I have no spare black UL listed ColecoVision 4 prong power cords that is something that I would not be able to offer for sale. However, if anyone has a broken ColecoVision power supply from the 80’s they could remove the power cord and install it on the AP-MP4ATX40 power supply. In fact the installation would be easier since a DB9 printer cord is not needed and the ColecoVision uses only 4 connections. It would also be a little bit cheaper to convert the power supply to work with a ColecoVision system.

 

If 25+ people wanted to make their own ColecoVision power adapter, I could get a custom ColecoVision waterproof sticker made up for around $5 each including shipping that people could stick on top of the Apollo 400 Watt Power Supply.

 

 

 

A Universal modular power supply should be developed for classic 70’s, 80’s, and 90’s computer systems

 

 

In the ideal world, some company should develop a fully modular power supply that outputs many different voltages. Then a person could purchase one modular power supply for around $100+ and then have a special ADAM power cord, ColecoVision power cord, TI-99/4a power cord, Commodore 128 power cord, ATARI 130XE power cord, and a modular power cord for around 10 different classic 70’s,80’s, and 90’s systems. Then one would only need to purchase one power supply and use the modular cord with special connector that works with the system.

 

A high-end Chinese company could make around 500+ fully modular power supplies that work with several different classic computers and videogame systems. Also if the power supply supports 10+ different systems there would be a demand for 500 power supplies. In the desktop PC world fully modular ATX power supplies with no -5 volts DC feature range in price from $45-$700. A high-end Chinese company could make something special in the $100+ price range that could work with several dozens of classic systems. It would be a universal modular power supply that would work with just about any system made. The power supply could be made cheaper if people were able to purchase the Commodore modular cord, ATARI modulator cord, and Coleco ADAM modular cord separately. Just purchase the modular cord that is needed.

I forgot to mention that the limited run of 26 Apollo 400 Watt Power Supplies with the custom Coleco ADAM wire harness installed were wired to the ATX power supplies Green Power Supply On wire to create an automatic detection feature. For example if this ADAM Power Supply power switch is turned on and the Coleco DB9 power cord is not connected to the Memory Console, then Power Supply remains off. As soon as the Coleco DB9 power cord is plugged into the ADAM Memory Console the power supply well turn on with the two fans spinning. As soon as one unplugs the Coleco DB9 power cord from the ADAM Memory Console the ADAM Power Supply immediately turns off. The best setup is to leave the Apollo 400 Watt ADAM Power Supply plugged into the Memory Console 24 x 7 and then when one wants to turn off the ADAM computer they just flip the power switch to the off position on the power supply.

 

If one chooses to convert their own ATX style power supply to work with the ADAM computer or ColecoVision, there are a couple of pieces of test equipment that can save one several hours. I have found that sometimes one can run into 2 defective power supplies out of a batch of 25 new ones. Before removing a wire harness and installing a ADAM or ColecoVision wire harness, you can save time by testing the ATX power supply to make sure it works properly. For several years I have owned a Thermaltake DR. Power II tester that currently sales for around $32.80 (There might be better quality and cheaper testers on the market now).  

 

However, I have ran into two defective -5 volts DC power supplies (two different brands and model numbers) that caused video interference issues when using composite video output on the ADAM and most likely would have had some RF video interference issues on the ColecoVision. In addition, there are some ATX power supplies on the market that claim to output -5 volts DC but in reality they do not offer that feature at all. Before a Coleco ADAM wire harness was installed I used the following device to make sure every power supply was in perfect working condition. This very high quality ATX breakout board from China for $6.95 plus free shipping is an awesome must have device that well instantly let one know if there is going to be any electrical problems or quality problems when the power supply is connected to the ColecoVision or ADAM computer. One just plugs the 20 pin or 24 pin ATX power supply into this breakout board and wires the black ColecoVision power cord or gray Coleco ADAM power cord to the breakout board. Then instantly one can verify the ATX power supply is going work with the ADAM computer or ColecoVision. If the power supply is bad, then one returns it for a refund, however if the power supply is good, then one can then open up the power supply and remove the wire harness and install the official Coleco ADAM wire harness or a official ColecoVision wire harness. Yes it costs an additional $6.95 for this hardware device that can take a few weeks or several weeks to arrive from China with free shipping option, however it’s a big time saver in case there is something wrong with the ATX power supply.

I don't usually do this but over $130 for a ATX power supply? I charged $130 shipping including for my custom supplies. I am not sure why the price is so high here. Having an original ADAM power cable is nice but in my case wasn't worth the price spike because of what ECOLECO charged for these cables. A ton of work went into mine and I am well aware how much work is going into yours. Of course people do have a choice. I am not trying to pick on you, just trying to understand the price point here. 

 

 

I offered this at $130 shipped

vs over $130 for this

By the way, Athena power supplies are as cheap as they can get. I gave my customers a lifetime warranty on any repairs IF they are ever needed. What are you going to do for yours? The first thing that goes on those ATHENA power supplies is the exhaust fan. How about making a power supply that doesn't need one?

I don't usually do this but over $130 for a ATX power supply? I charged $130 shipping including for my custom supplies. I am not sure why the price is so high here. Having an original ADAM power cable is nice but in my case wasn't worth the price spike because of what ECOLECO charged for these cables. A ton of work went into mine and I am well aware how much work is going into yours. Of course people do have a choice. I am not trying to pick on you, just trying to understand the price point here. 

 

 

I offered this at $130 shipped

vs over $130 for this

By the way, Athena power supplies are as cheap as they can get. I gave my customers a lifetime warranty on any repairs IF they are ever needed. What are you going to do for yours? The first thing that goes on those ATHENA power supplies is the exhaust fan. How about making a power supply that doesn't need one?

When I purchase power supplies, I always purchase the best quality available. For example I have built Desktop PC’s using the top of the line EVGA SuperNOVA 1600 watt T2 for around $400. However the problem is absolutely no fully modular ATX power supply exists on the market with -5 volts DC.

 

The reason why I picked Athena Power’s Apollo 400 watt power supply is because it’s the absolute best ATX power supply on the market that has the legacy discontinued -5 volts DC feature. The MTBF on the power supply is 100,000 hours. There are over a dozen ATX power supply manufactories that I had to eliminate because all or most manufactories no longer offer -5 volts DC feature for the ATX power supply.  

 

I went into details why the price is $130 and I also mentioned how ATARIAGE readers can get a 20% discount off that list price. I also went into details on how someone can install their own wire harness on their own Apollo 400 watt power supply for around $70 including power supply if they already own the proper tools. So one can make their own power supply for around $70 if they want too.

 

Both your custom power supply and the Athena Power supply with ADAM wire harness are the exact same price. Offhand I do not know what power supply you are using, however most people are using a $15 50 watt Mean Well RT-50 power supply and making their own custom neat looking plastic case. That is really amazing that you are giving your customers a lifetime warranty on your power supply which is way beyond the official manufactories warranty (if you are using a $15 power supply that is very economical replacement). Even the $400+ top of the line EVGA power supplies only have a 12 year warranty. This $35 Athena Power supply I am matching the manufactories warranty of 1 year. Just about everything I sale has a 60 day return policy, plus this power supply has a 1 year warranty directly from the dealer. After the 1 year warranty if the power supply breaks, I may offer the option to repair the power supply for a repair fee. All ATX power supplies have fans. There are advantages and disadvantages to having fans.

Way overpriced for a cheap atx power supply with a cable swap

I dont care how much your wire strippers cost thats your problem

I went into details on how you can make your own for $70 for those that do not want to purchase one with the wire harness installed. I was never complaining about the price of the wire strippers, I was just letting people know where to get a very good quality automatic wire strippers.

  You can spin this however you want but the bottom line is you're charging over $130 for a bulky ugly atx power supply with a cheap label slapped on there. My supply in parts alone was about $70 leaving me $60 to cover shipping which gave me an average of less than $40 to cover my labor. Ask those who own one how much hand work went into mine. In the time it takes to make my supply I can do 4 of yours. Millie's price tag is justifiable for his power supply, yours is not. Oh and get out of here with your explanations on why you're charging this, there ain't a damn thing you can teach me about power supplies.

I do like the look of your plastic case better however all desktop style power supplies use metal cases which I prefer over plastic (The label is full color vinly and waterproof, it is the best quality and most expensive that the printer company had). Also this Apollo 400 watt power supply is super small when compared to a full size ATX power supply, since it uses a micro SFX design, it is only ATX when it comes to the ATX style of wire harness used before it received a Coleco ADAM wire harness. Before you entered this thread I mentioned in detail how people can build their own Apollo 400 watt power supply with ADAM wire harness, and the parts including power supply is around $70.45. Therefore both of our power supplies are the exact same cost.

Thanks! I placed my order.  There is NO WAY IN HELL I am buying anything from HDTV1080P. I don't support shady resellers who are just trying to trick the community into lining his pockets with money.

Yeah that's the problem, our supplies are the same price! You're selling a much inferior product. Listen, I've said all I need to say about this. Great thing is we all have freedom of choice. Wonderful to have all the details out in open to help with that choice.

If you must have the last word it's all yours. Ok? Ok...

I am glad your replacement Coleco ADAM power supply is available now for $99.99 fully assembled. You must have located some spare Coleco printer power cords. However when I click on the link you made it actually takes people to my power supply at the beginning of this thread.    

 

Here is the correct link to where people can purchase your power supply.

Its nice that ADAM owners have a choice between at least 2 different third party power supplies. I use to offer converted PC power supplies with a ADAM wire harness back in the late 80's for the ADAM community. This is just a updated improved design.

I dont think I have ever seen a metal desktop power supply, those are reserved to be inside another enclosure

The following is more detailed electrical connection information on how to connect the Coleco ADAM wire harness to a 20 pin or 24 pin ATX power supply that offers the legacy -5 volts DC feature

 

 

 

It is recommend to use the following ATX breakout board mentioned in a prior post at this link. This allows one to test the ATX power supply with the Coleco ADAM wire harness before actually removing the old wire harness and installing the new Coleco ADAM wire harness.

 

 

On the existing factory installed ATX power supply wire harness there are many different wires that are color coded. For the Coleco ADAM computer the +3.3 volt DC orange wire, the -12 volt DC blue wire, the +5VSB purple wire, and the gray wire is never used. Therefore, never connect anything to the orange, blue, purple, and gray wire inside the ATX power supply when installing the Coleco ADAM computer wire harness.       

 

(Step One): The Coleco DB9 power cord pin 1 brown wire is +12 volts DC and is connected to any of the +12 volt DC yellow wires inside the ATX power supply.

 

(Step two): The Coleco DB9 power cord pin 2 red wire is +12 volts DC and is connected to any of the +12 volt DC yellow wires inside the ATX power supply (Since there is plenty of yellow wires in the power supply, use a different yellow wire then what was used in step one).

 

(Step three): The Coleco DB9 power cord pin 3 orange wire is +5 volts DC and is connected to any of the +5 volt DC red wires inside of the ATX power supply.

 

(Step four): The Coleco DB9 power cord pin 4 yellow wire is -5 volts DC and is connected to the one and only -5 volts DC white wire inside of the ATX power supply (This -5 volts DC is a rare feature that does not exist on all or most modern ATX power supplies).  

 

(Step five):  The Coleco DB9 power cord pin 5 Green wire is a ground wire that connects to any of the black ground wires inside of the ATX power supply.

 

(Step six): There is a bare metal wire on the Coleco DB9 power cable (also called a drain wire). Insulate this wire with either heat shrink tubing or use UL listed electrical tape to wrap and insulate this bare wire. This Coleco DB9 power cord bare wire is connected to the one and only power supplies power on detection circuit (green wire). So after insulating the Coleco bare metal wire, attach the wire to the one and only green wire on the ATX power supply. When every the Coleco ADAM DB9 power cord is connected to the ADAM memory console the power supply well turn on if the power switch is in the on position, however if someone disconnects the Coleco DB9 power cord from the ADAM memory console the power supply well automatically turn off.

 

The above 6 connections are all that is needed to use the Apollo 400 watt power supply with the ADAM Computers Memory Console. If one wants to connect the ADAMNET communication to the power supply for the connection of the original Coleco ADAM printer then read the following section.

 

Connecting the second DB9 cable to the Power Supply for ADAMNET Printer communication

 

 

The following additional wiring well allow one to connect their original Coleco ADAM printer to the power supply (The power supply in the printer runs cooler since the printer power supply only powers the ADAM printer instead of powering the entire computer system). In addition the bug where the ADAM printer carriage return advances one line space each time the computer Memory Console reset is pulled has been fixed, if one follows the following wire configuration for ADAMNET communications. When one wants to print they just turn on the ADAM printer and pull the Memory Console reset button so that ADAMNET sees the printer (Save any important files before resetting the computer).

 

A Gold plated DB9 28 gauge fully shielded cable can be purchased for $5.45 plus free shipping from Cables Online. This cable is for ADAMNET printer communication.

 

(Step seven): Cut the female DB9 connector off the end of the cable and then strip the wires off that you need. Be carefully and make sure you only cut the female DB9 end off the cable, if one cuts the wrong end off then a replacement cable for around $5.45 well need to purchased. On this cable only the green and blue wires are used.

 

(Step eight): Attach the green wire on the DB9 cable to any of the black ground wires inside of the ATX power supply (Since there is plenty of black wires in the power supply, use a different black wire then what was used in step five).

 

(Step nine): Attach the blue wire on the DB9 cable, to the one and only purple wire on the Coleco ADAM DB9 power cord. Never attach the purple wire on the ATX power supply to the ADAM wire harness. That purple wire on the ATX power supply is never used.

 

(Step ten): The blue wire on the Coleco ADAM DB9 power cord is not used for this project and should be insulated. In fact make sure all cables including the ones that are not being used are insulated with no bare wire sticking out the end so that the Apollo 400 Watt power supply does not go into protection mode from a short circuit. There are several ways to remove and attach a different wire harness to a power supply. Some people might solder the wires directly on the power supply circuit board while other people might use special high quality UL list or approved crimp on connectors. To insulate a bare wire at the end of a cable that was cut off one might use UL listed crimp on plastic connectors that sale for around $6.14 for a bag of 1,000. Many of the crimp on connectors require a tool like the SG Tool Aid SGT18980 crimping tool for around $100 which makes a perfect crimp every time.

 *** Limited run of only 27 power supplies outfitted with a custom Coleco ADAM wiring harness ***

 

I just recently purchased another Coleco ADAM DB9 power cord from a ADAM Computer dealer for around $20 (it was the last one they had in stock). Therefore the limited run has been officially increased from 26 power supplies to now 27 power supplies.

On September 17th 2018 the United States Trade Representative announced  a new 10% tariff that went into effect on September 24th 2018 for some Chinese products, including computer power supplies. That tariff rate well increase to 25% on January 1st 2019. This means USA consumers well be soon paying around 25% higher prices for computer power supplies and other electronics.

#1) there is no standard color coding on DE9 (you incorrectly refer to it as a DB, there is a difference) and even manufactures will get colors going to different connections from lot to lot

#2) you do not need UL approved tape and connectors for low voltage DC

#3) you do not need 100$ crimpers to perform these tasks, much like you do not need a 70$ wire stripper 

#4) quit talking to us like we are fuckin morons

#5) don't post bullshit scare tactics to push your sales

 

5 in particular no, consumers wont be paying 25% more for a power supply magically overnight. The companies who build power supplies in the US will have to pay 25% more for components. Those made in other places wont have to pay the tariff, and there's not a tariff on finished electronic goods, which makes the entire thing fucking stupid but I wont get into that as it gets into politics
