Hello guys this is a improment over the past tutorial posted for converting a PC power supply to be a bench 12 volt supply. This tutorial uses the same computer PSU to make a adjustable 0 to 24 volts. This means testing equipment of different voltages will be much easier. Now you don't need to hunt down a ad adapter and cut it up only to find it's not really the voltage you needed.
Here is the YouTube video for the author. Hopefully you found this useful I plan to make one of these myself as it would be very useful.
Here is the original tutorial but I wanted to post it because you never know if the link will go dead
It uses the ATX supply and routes the -12, 3.3, 5 and 12 volt ATX outputs to screw terminals, each protected by a 1.25 amp resettable polyfuse.

Thanks for any help
Worked fine for me without it.
"A 9 Watt load resistor is included but not soldered to the board. In our experience most modern ATX supplies don't require a significant load on the 5 volt rail to start. An artificial load just wastes electricity and creates unnecessary heat. Please let us know your experience."
