How to make your own ColecoVision Power Supply that operates between 100-240 Volts at 50/60Hz
I was originally going to post this thread around a week ago, however I ended up getting very busy multi-tasking with several different projects going on, therefore I am taking the time to post the thread now.
600 Watt Titanium Nicked Coated ColecoVision Power Supply
Below is a picture of a top of the line Titanium Nickel coated 600 Watt XION PowerReal ATX Power Supply that has a ColecoVision UL listed wiring harness installed. This original Coleco cord was removed from a defective 36 year old ColecoVision Power Supply and installed on a factory new XON-600F147-201 600 Watt Power Supply.
I was only able to locate one factory new Titanium Nickel Coated 600 Watt Power Supply with the -5 Volts DC feature for around $35 after shipping. I am considering keeping this power supply for myself because I cannot get anymore and it’s the only -5 Volts DC power supply that I have seen that offers up to a 1 Amp output for both the -5 Volts DC feature and the -12 Volts DC feature. ATX power supplies with the -5 Volts DC feature are not being made anymore, and around 95% of the ones that were made with -5 Volts DC feature only have 0.5 amps capacity and not the full 1 amp capacity. What this means is that if I had a spare ADAM Memory Console Power cord (Also called an ADAM printer power cord), then this 600 Watt Power supply is powerful enough to power a ADAM computer and a ColecoVision at the exact same time. The problem is I used up all my spare ADAM Memory Console cords. However, it would have been very cool to have both an ADAM and ColecoVision power cord coming out of the same power supply. This 600 Watt Power Supply can literally power 10 ColecoVision game systems at the exact same time if I had 10 ColecoVision power cords to connect to the power supply. Perhaps one day a third party company well make a ColecoVision and ADAM compatible power cords that are the same quality or better quality when compared to the original Coleco versions.
I might end up keeping this 600 Watt power supply because I cannot find anymore new ones, and it’s a lot more complicated and takes around twice as long to modify when compared to the already time consuming Apollo 400 Watt Power Supply for the ADAM or ColecoVision. The fan controller circuit board for this 600 watt power supply makes onscreen RF noise when connected to the ColecoVision game system. Therefore, to fix this RF noise issue one needs to unplug the fan from the fan controller circuit board and remove the variable manually fan speed control, and then plug the fan directly into the main power coming out of the power supplies wire harness. In addition these power supplies are designed to be enclosed inside a system case where the fan is designed to move extremely warm air out of the computer case. When the power supply is outside of a system case one can slow down the fan to make the power supply very quiet while at the same time providing plenty of air flow that keeps the power supply cool. The way a variable fan power supply works is that the fan is connected to 12 volts for full speed, 5 volts for slower speed, and 3.3 volts for the slowest speed. Therefore, this power supplies fan was manually wired to the orange 3.3 volts and the black ground wires of the power supplies wire harness to make the fan super quiet. I also did not like the blue LED lights on this power supply when using the ColecoVision in a dark room, therefore I removed the blue LED function from the power supply fan so that it no longer lights up.
This 600 watt power supply is the best power supply that I have ever seen with the -5 volts DC feature but I cannot find anymore new ones on the market to offer it in QTY (plus I do not have any more original Coleco power cords). MTBF rating is over 100,000+ hours on this power supply. The build quality on this 600 Watt power supply is outstanding and if I was going to sale it I would give a 2 year warranty however because of the labor involved most people would not pay $149.99 for this power supply. If one can find a new or used 600 Watt XON-600F147-201 (UPC 842431031037) power supply I do not recommend buying it for the ColecoVision or ADAM since there is a massive amount of modifications that need to be made to make it work properly for a classic ColecoVision or ADAM computer.
However here is pictures of the one and only 600 Watt Titanium Nicked Coated ColecoVision Power Supply (this power supplies case is scratch resistant compared to other power supply cases that I have worked with).
