I decided to do this project to have one for myself. $8 'ATX' supply to use for a bench supply around the house. Not bad.
The bad news...I am not sure if this thing is an actual ATX power supply. The pin out and wire colors are not the standard that I have read on numerous websites.

Just to name a few. Red is +5V, Black is ground, Orange is 3.3V so on and so forth.
But the power supply my buddy gave me is so far off this industry standard and I have no luck finding a pin out. So I had to open the supply. Thankfully, the PCB board lists the voltages next to the wires:
Red +5V
Black Ground
White -18V
Orange +12V
Yellow -12V
Purple -5V
Grey Power Good
And there are two brown wires that I have no idea what they are. The PCB shows P/C and F/C on the board connections. Any ideas?
