I just received another ATX power supply made in China from a USA dealer that I purchased this week. The USA dealer advertised online the power supply having -5 volts at up to 0.8 amps, however those specs are far from reality. The power supply also on the retail box and actual specs on the power supply label says it outputs -5 Volts at up to a maximum of 0.8 amps. However, when I connected the ATX power supply up I discovered that it does not output -5 Volts like advertised. What has happen is all ATX power supply companies over the last few years have stopped offering the -5 Volts feature since it is no longer required after ATX version 1.2 or 1.3. Some of the power supplies that had -5 Volts went completely out of production, and the other ones kept the same model number but removed the -5 Volts from both the power supply and the official power supply specs. However, there are some companies for several different model numbers that have removed -5 volts feature but never removed the -5 volts from the official specs printed on the power supply label. Therefore finding -5 volts on an ATX power supply in 2018 is almost impossible unless a dealer has old inventory.
If one needs the -5 volts feature on an ATX power supply, stay away from the Athenatech brand. Both the Athenatech PS-450WX1 and the Athenatech PS-400WX1 (UPC#875783009706) are models that have removed the -5 Volts feature but still list the -5 Volts feature in the manufactories specs on the power supply label. I have always said that when a manufacturer changes its specs on a model that has already been released, then that manufacture should be required to stop making that model and come out with a new model in order to avoid consumer confusion. To make matters worse when a manufacture like Athenatech removes a feature like -5 volts from a power supply they should be required to change the label on the power supply so that the -5 volts feature is no longer listed.
When and if this special ColecoVision USB power supply converter is released on the market. I hope the next power supply converter will be for the Coleco ADAM computer since it has advanced Supergames, etc. There are many ColecoVision owners that purchased Expansion Module #3 ADAM computer since certain people were able to obtain a working ADAM power supply but had a hard time finding a working ColecoVision power supply. The nice thing about Coleco’s expansion module interface is one can bypass ColecoVision power supply socket and using a product like the ADAM computer to power the ColecoVision. Technically its possible for someone to come out with a power supply for the ColecoVision that plugs into the expansion module interface if they did not want to use the existing power supply socket on the ColecoVision.
