You can try testing the ATX power supply by removing it and taking the main connector of wires, and instering a paperclip or something to short the green wire to ground (black) If its an ATX its the only green wire there is on that connector. It should turn on the power supply. You really dont need a model number. Just know what size you need and how much wattage you think you'll need they all pretty much do the same thing. 3.3v(orange) ,5v,(red) and 12v (yellow).
also comes in handy if you ever need a power supply for.... whatever. Since they are so versatile. Im currently finisng up a project using a Cdrom for a cdp, powered by a computer PS. More on that next week when its all done though.
