Sega Genesis 1 Power Supply comments

[HDTV1080P]

The Sega 1602 plug in power supply label says 9 volts DC at 1.2 amps and the Sega 1602-1 label says 10 volts DC at 1.2 amps. However, the Sega 1602 power supply that is labeled as 9 volts DC 1.2 amps is a unregulated power supply and when no load is on the power supply the 1602 power supply outputs around 13.29 volts DC, and when the power supply is connected to a Sega game system under a load the power supply outputs around 9 volts DC. Unregulated power supplies are cheaper quality when compared to a regulated power supply. One can also use a modern third party 9 volts DC regulated power supply with the Sega Genesis 1 videogame system as long as the power supply outputs a minimum of 1.2 amps (negative tip). A regulated 9 volt DC power supply well maintain 9 volts DC all the time at no load and under a load as long as one does not exceed the power supplies maximum output current capacity.

 

One nice feature of the Sega 1602 power supply is that the cord length is 11.5 feet long. Its not possible to find that long of cord on all or most modern day power supplies unless special ordering in huge QTY's from China. Power Supply companies to make the power supplies cheaper in cost have made cords in the 2 feet, 3 feet, 4.5 feet, and 6 feet sizes. Its even hard to find a 6 feet power cord attached to a DC power supply.

I use a modified Gamecube power supply on my setup to power the Genesis - 32x - and Model 1 Sega CD from a single switching supply.

 

However, it does output a constant 13v with and without load. But not an issue since the VRs in them are rated to up to 15 - 18v inputs.

 

And the 'Cube supply puts out 3amp. So it has been wonderful to only need on outlet plug for all three.

So even though the specs say use 9 volts DC, you are saying that you have been able to use 13 volts DC without a problem since the voltage regulators can handle between 15-18 volts DC.

 

When selecting a third party power supply I would prefer to use a 9 volts DC model at 3 amps or higher. I have plenty of high quality 12 volt DC power supplies with 3 amp and 5 amp output, however I decided not to try those adapters even though the plug fits. In the future I might try some high quality 9 volt DC models on the Genesis system that are 3 amp and higher (only need a minimum of 1.2 amps according to the specs).

Each component you add to the Genesis tower of power basically requires 1amp to operate. In fact I believe the actual VRs in the model 1 genesis are only 750ma rated output VRs. But there is a pair of them in the console. But yes, most VRs can handle 15+ volts with some newer ones able to handle input voltages in the 20+ range. It doesn't hurt the VRs as long as the input voltage doesn't exceed their max input rating. In fact, you actually need a more input voltage for the VRs to kick in and provide the proper output voltage. If you don't then they end up dropping the output current from them to keep up or simply not work at all.

 

This is also why the unregulated adapters without a load on them are about 13v as well. In fact I just measured one of my original 1602 genesis model 1 PSUs the other day and it was generating over 14v without a load.

 

The more input voltage on the VRs, the more they give off as heat as I understand it. So if anything my VRs might run a bit hotter than normal. But I also installed replacement VRs that actually ouput up to 2amp from them instead of the usual 750ma - 1a of the originals.

 

So yes, each add on basically needed 1amp to operate. That is why each PSU needed for the various add ons, all basically have the same specs on the PSUs. If you add additional components like AV mod boards additional audio amps..etc to the insides like I do, then you need to consider replacing the VRs with higher output variants anyway.

 

It says 9v but in reality everything inside the Genesis and most classic consoles (Exceptions are the Colecovision and Intellivision), actually take that 9v input and drop it down to +5v for everything inside the system.

The original Sega 1602 adapter only works on 120 volts at 60Hz. The advantage of most 21st Century DC adapters is they operate between 100-240 volts at 50/60Hz for those people that need to use the Sega system anywhere in the world when traveling or when one lives in another area of the world.

[HDTV1080P]

High Quality Sega Genesis System one regulated 9 volt DC power supplies that operate worldwide between 100-240 VAC at 50-60Hz

When searching for a power supply for the Sega Genesis System one, the most difficult and time consuming issue was trying to find an external adapter that was legal to import into the United States per the February 10^th 2016 Department of Energy level VI energy efficiency laws. All manufactories of external power supplies inside and outside the United States are required by law to manufacture their external power supplies so that the power supplies are level VI energy efficient as of February 10^th 2016. In addition, any external power supply imported into the United States as of February 10^th 2016 has to be level VI complaint. Existing resellers in the United States that have old power supplies that were manufactured and imported into the United States before February 10^th 2016 are allowed to continue to sale their old inventory.

 

The problem is there are many Chinese power supply companies that are not following the level VI DOE law and are shipping old level IV and level V stock into the United States in 2018. While I realize USA dealers are allowed to have old stock that was imported prior to February 10^th 2016, the problem is there are many USA power supply dealers that are advertising Chinese power supplies as level VI efficiency and instead shipping out level IV and level V power supplies since they have old stock. To make matters worse when ordering from some USA dealers the power adapters are shipped directly from China to ones USA address and some of these Chinese companies are shipping out level IV and V power supplies in 2018 which is in violation of the Feb 10^th 2016 DOE law. While it is nice to have power supplies and other products that use less energy, the problem is unless this law is enforced it becomes very time consuming hassle for resellers and consumers that are trying to follow the law, since some Chinese power supply companies are not following the DOE level VI law.

 

There is several 9 volt DC power supplies I ended up returning from several different companies since I paid a premium price to get the advertised level VI efficiency level and instead received old stock of level IV and V efficiency.

 

 

For the Sega Genesis System which requires 9 volts DC with a negative tip, only the TRIAD Magnetics brand meets the level VI energy efficiency requirement and power output requirements

The second hardest issue when selecting a power adapter for the Sega Genesis system one is finding a 9 volt DC power adapter that is both negative tip with level VI energy efficient. The selection of 9 volt DC power adapters is a lot larger if one is looking for a positive tip instead of a negative tip. According to Digi-key’s database there is only 17 in production power adapters that are level VI, 9 volt DC, and a negative tip. Out of those 17 adapters less them 10 of the Triad Magnetics models has enough power to be used with the Sega Genesis system one and has the correct plug size.

 

While some of the spec sheets claim 5 feet and 6 feet cords for the TRIAD Magnetics 9 volt DC adapters, after measuring 3 different models the actual cable length of the adapters is around 5.5 feet.

In addition, the original Sega Genesis system one requires a negative tip that is 2.1mm x 5.5mm x 11mm. All Triad 9 volt DC power supplies are either UL listed or conforms to UL Standards, they also are FCC certified, and have Canadian standard CSA safety, and with CE certification for Europe.

 

Triad Level VI compliance Notification

 

The following TRIAD power adapters also come with a 5 year warranty.

 

The top of the line adapter to use with the Sega Genesis System one is the TRIAD WSU090-3500-R

Triad Magnetics makes nice regulated 9 volt DC power supplies that is smaller and better quality when compared to the original Sega Genesis unregulated power supply. TRAID power supplies also operate between 100-240 volts at 50/60Hz. For example, the Triad Magnetics WSU090-3500-R has a 3.5 amp capacity and can power anything that I hooked up to the Sega Genesis System one (Power adapter plug makes a perfect fit on Sega Genesis System one). I connected the Sega Master System Power Base converter that worked fine. The Genesis 32x and Model 1 Sega CD use their own separate power supplies, however with 3.5 amp power supply capacity and the correct y adapter this Triad Magnetics power supply should have no trouble powering all 3 components at once. This TRIAD WSU090-3500-R power supply costs around $20 each. What was really disappointing is that after several samples from several different USA dealers that advertised this adapter as level VI energy efficient, every adapter I received was only level IV energy efficient because of old stock.

 

The Sega Genesis system one 2.5 amp TRIAD WSX090-2500-R with international worldwide plugs and with verified VI energy logo code on adapter

The TRIAD Magnetics WSX090-2500-R comes with North America plug, European Union plug, United Kingdom plug, and Australia/New Zealand plug. This adapter allows one to use the Sega Genesis system one anywhere in the world. With 2.5 amps of power everything worked fine with the Sega Genesis (Power adapter plug makes a perfect fit on Sega Genesis System one). I purchased this adapter TRIAD WSX090-2500-R for around $15.77 with free shipping from Arrow.com and the two samples I received were both energy efficiency level VI.

 

The 2 amp TRIAD WSU090-2000-R works with both the Sega Master System and Sega Genesis System One

The advantage of the TRIAD WSU090-2000-R is that its 100% compatible with both the original Sega Master System and the Sega Genesis System One. The Sega Master System does use a 2.1mm x 5.5mm x 11mm plug which is the same size as the Sega Genesis System One plug. The reason why the 3.5 amp TRIAD WSU090-3500-R power supply and the 2.5 amp TRIAD WSX090-2500-R does not work with the original Sega Master System is because the plastic base where the metal tip is attached at the end of the cord is too large. On the TRIAD WSU090-2000-R the plastic base is thinner and makes a perfect fit on both the original Sega Master System and Sega Genesis System One. This 2 amp TRIAD WSU090-2000-R power supply can be purchased for around $12 each. However so far all my samples are only energy efficiency level V and not the claimed VI that is advertised. I am waiting for one more sample from another supplier to see if they have stock that is level VI energy efficient per their claimed online advertisement specs. If I do receive level VI energy efficient 2 amp TRIAD WSU090-2000-R power supplies I well post which supplier is selling them (but I have my doubts that I well get level VI power supplies).

 

In theory the 1.3 amp TRIAD WSU090-1300-R that sales for around $9 in theory should work with both the Sega Master System and Sega Genesis System one. However, I have not personally tried this low cost model and have no plans to try this model, but the specs claim the adapter should work. Yes its $3 cheaper and all one really needs is 1.3 amps to power one Sega game system. However, the advantage of the 2 amp TRIAD WSU90-2000-R for $3 more at around $12 each is that one has extra power capacity for possible future use.

 

What every TRAID adapter one chooses to use with the Sega Genesis System One, it is awesome that there is a big selection of adapters that well work with the Sega game systems. However receiving an actual TRAID 9 volt DC power supply at the end of 2018 with an energy efficiency level VI rating is the biggest challenge since most people instead get old pre 2016 stock that is either level IV or V.

What is the best option if you're looking to replace a model 1 or Sega CD adapter? I recently got a model 1 Genesis and then picked up a model 2 Sega CD from eStarland that had no adapter with it. Instead, I bought one of the Retro-bit adapters and plugged the Genesis into that, and put the original Genesis adapter on the Sega CD. Now the video is full of noise, and I'm sure it's this cheapy power supply, and not the Sega CD. BTW, for $100 I think I got a good deal. It doesn't have the extender or any of the other hardware, but the Genesis just slid right on and the CD drive works perfectly with my copies of NBA Jam and Willy Beamish. Now I just gotta save (and save and save) for a copy of Shining Force CD, since that's really why I wanted the system.

 

Anyway, I'm looking at the Retro Game Cave Duo-M1 and Trio-M1 (because I'm also considering a 32X for this setup) and not necessarily loving the prices. $45 or $60 for a device that plugs in two to three old consoles *seems* like a lot. The 80-plus Gold PSU in my PC didn't cost me $60, but these are low-volume parts.

 

Does anybody have a Duo or Trio? Is it a good solution?

I do not own one of the trio adapters no. Again I'm using a modified gamecube power supply that has the power plugs coming out of it to power my model 1 genesis and sega CD and my 32x. The gamecube PSU is a switching PSU and puts out 13v exactly with a 3amp max output. Pretty much perfect for the genesis full add one combo set. I reads somewhere that you can actually modify the sega CD units in such a way that they will actually get their power from the Genesis power supply and turn one at the same time etc... But I would still think you need to use a 2amp or better supply to make sure enough juice is getting to everything.

I have the same Gamecube power supply setup for my model 1, SCD, and 32X. LOVE IT. Might have to check on that tri thingy for a backup. I got mine from goldenax long time ago. Does anyone still make those?

Yeah Golden.Ax is where I got my adapter from as well. Turns how he doesn't make them...but...

 

His wife does. So I think it was like $35 shipped or something at the time. I sent him a PM as he isn't very active and received a reply a few days later. Course this was all like 2 or 3 years ago now. My only issue with that adapter is that the power cords for the systems aren't very long. Like maybe 3 or 4 ft each? As a result, it was a very tight fit length wise for the power cords to actually reach the system where I have it in the setup.

 

Still has been an excellent PSU and I've never had any issues with the system setup that I could deem as being power related. It could be part of the reason why my Genesis appeared to be overheating though sometime back. The switching supply doesn't seem to drop voltage from a load. So you always have that 13v going into everything. Not really a problem but that extra voltage does cause more heat to be given off by the VRs inside the system.

[derFunkenstein]

Doesn't look like those GameCube power supply options are available anymore then?

[derFunkenstein]

Well, I've ordered an M2 Duo from Retro Game Cave. That'll run the 32X I just ordered and Sega CD model 2 I got last week (mentioned in a previous post), and the Genesis can use its own. Having one big and one little connector gives me the most flexibility, as that would run a model 1 Genesis + 32x, model 2 Genesis + model 2 CD, or a 32x + model 2 CD with whatever Genesis I want to buy in the future since I'll have one original PSU of each (with the 32X connector being compatible with model 2).

 

edit: congrats to me on surviving 1,000 posts.

Well done, thought of this a couple years back and did it myself.

 

Gamecube power supply add Cheap chinese Genesis/NES/SNES donor cable, soldered inside and hole in case for strain relief. Get a single female to 3 male splitter off Ebay.

 

Did this a couple years ago. Tower of power solution. I don't have a 32X, just use my fully refurbished JVC Model 1 Sega CD and my Non-TMSS Genesis

Update on power adapters for the Sega Genesis System One

 

As of August 2019 the selection of power adapters has not changed. The required level VI energy efficiency and negative 9 volt tip is limited to only some high-end models from the TRIAD brand. I just recently ordered from Digi-Key, and they still have old stock for the top of the line 3.5 AMP TRIAD WSU090-3500-R (I received level IV energy efficiency power adapters instead of level VI which is mentioned on their website, so I returned the TRIAD WSU090-3500-R for a refund). I have been buying many different adapters over the years from Digi-Key, and they are better than most suppliers are since they normally send you exactly what is listed on their website and company spec sheets. In fact, the TRIAD WSU090-3500-R is the only adapter that I have purchased from Digi-Key in the last few years that was advertised as level VI and instead I received level IV (That type of problem occurs more often with many other companies, and does not happen to often with Digi-Key). I have completely given up on trying to find a dealer in the USA that offers the top of the line TRIAD WSU090-3500-R adapter with the required level VI energy efficiency as the claimed spec sheet from TRIAD mentions. Instead, one is sent level IV energy efficiency from old pre Feb 2016 stock.

 

For the first time ever I was able to find a USA dealer that has the 2 amp TRIAD WSU090-2000-R with the official level VI energy efficiency rating. As far as I am aware Digi-Key is the only supplier shipping the TRIAD WSU090-2000-R with the official level VI energy efficiency rating (when other dealers clear out old stock of level V energy efficiency adapters then they should be getting in modern level VI adapters).

 

TRIAD changed the design of the WSU090-2000-R adapter and the current in production adapter no longer works with the Sega Master System

 

 

We live in a complicated technological world. The old TRIAD WSU090-2000-R adapter that has the official level V energy efficiency rating, it works perfectly fine with both the Sega Master System and the Sega Genesis System one. However, the current TRIAD WSU090-2000-R adapters manufactured with a level VI energy efficiency rating does not work with the Sega Master System because the plastic base where the metal tip is attached at the end of the cord is too large (The old level V TRIAD WSU090-2000-R plastic base is thinner and makes a perfect fit on both the original Sega Master System and Sega Genesis System One). Another thing that has changed is that all TRIAD adapters use to be UL listed, and when TRIAD switched to energy efficiency level VI they decided to drop the UL listing which is an optional certification in the United States. So all level VI TRIAD adapter models that I have seen so far use UL recognized material instead of paying for an official UL listed certification process. When specs change on electronic products like power adapters, then manufactures should be required to change the model number. Here we have the exact same model of adapter with a 2.1mm x 5.5mm x 11mm metal plug, but because on the new level VI version of the adapter plastic base is made thicker where the metal tip is attached, the exact same model of adapter that use to work in the Sega Master System will no longer work at all since the plug no longer fits.

 

Therefore, at this time only the Sega Genesis System One works with the TRIAD adapters. I mentioned before that I have no plans on trying the lower end 1.3 amp TRIAD WSU090-1300-R adapter which is around $9, however since TRIAD made changes to the 2 amp TRIAD WSU090-2000-R so that it no longer works with the Sega Master System, I am now planning on testing the lower quality TRIAD WSU090-1300-R which uses a thinner 20 gauge cord compared to the 18 gauge cord on the other TRIAD adapters. Maybe the TRIAD WSU090-1300-R might use a thinner plastic base so that it might work with the Sega Master System.

Maybe one day more electronic manufacturing might come back to the United States

 

China makes both high-end products and lower end products in their automated robotic factories. When it comes to electronics, the entire world including Japan, Europe, Australia, and the United States gets many of their products made in China. Close to 100% of consumer electronic products are being made in China. If tariffs were to keep increasing on China products, then perhaps gradually over decades companies might decide to make more automated robotic factories in the United States. One day many more products might be made in the United States again if the manufacturing sector returns to the USA.

    

Inflation is occurring on high-end Chinese parts. One of the power adapters I have been purchasing for a non-Sega related product use to cost $9.99 plus free shipping back in January of 2019. Today in August of 2019 that same exact power adapter costs $13.99 plus shipping. That is around a 30% price increase. I asked the company why the product went up around 30%. They mentioned it might be because of 25% Chinese tariffs occurring. This year some USA dealers raised product prices from China between 10% to 30% because of tariffs. However many Internet based companies are charging consumers up to a 10% tariff tax fee right next to the sales tax on the invoice if the product comes from China. Some companies instead of raising their product pricing on their entire website are collecting up to 10% tariff taxes at the checkout for Chinese products (When consumers are charged around 8% sales tax in some states on top of 10% tariff tax, that is around 18% in taxes on the product they are buying). For example purchase a Chinese product from Digi-Key like a TRIAD adapter, you will see the 10% tariff tax at check out right next to the state sales tax. Many other web based companies are doing the same thing that Digi-Key is doing. As tariffs increase on Chinese products more consumers will start buying more products made in the USA and more companies will start building automated robotic factories in the United States. Building factories can take over 10 years and sometimes decades as manufacturing slowly returns to the USA.

The low cost TRIAD WSU090-1300-R works with both the Sega Master system and the Sega Genesis system one

 

The TRIAD WSU090-1300-R regulated power supply puts out a stable voltage of around 9.2 volts DC under no load and any load up to 1.3 amps. The input voltage of this power supply can be between 100-240 volts DC at 50/60Hz. The plastic plug mold is a perfect fit for both the Sega Master System and Sega Genesis system one. Besides having the required energy efficient level VI rating from the Department of Energy, the adapter also is FCC certified, uses UL approved material(conforms to UL standards), and is certified to Canadian CSA standards. In addition, the adapter has the ETL listed certification mark which some people claim ETL listed is just as good as UL listed products (Also a RoHS product). The 20 gauge power cord is listed as being 6 feet long in the spec sheet, the sample I measured was 5 feet 9 inches long. Most TRIAD power supply cords are around 5.5 feet long when measured (so if one rounds up it is a 6 feet cord). TRIAD offers a 5 year warranty on their power supplies, and they have an excellent build quality.

 

 

When the 9 volt DC (negative tip) 1.3 amp TRIAD WSU090-1300-R power supply is connected to the Sega Master System, the adapter puts out the needed 0.85amps (850ma) for the Sega Master System. Everything worked perfectly fine with this adapter while using the Sega Master System. This TRIAD adapter also worked fine while using the Sega Genesis system one including while using the Power Base Converter expansion module. The Sega Genesis system one draws 1.2 amps from the 1.3 amp TRIAD WSU090-1300-R power supply.

For around $9 plus taxes and tariff fees the TRIAD WSU090-1300-R can be purchased from Arrow.com and the ones I received have the energy efficiency level VI logo on the power supply (Free shipping on orders over $50 and larger adapter QTY’s get a discount).
