i need to test my power supply, can anyone tell me which wires i have to connect to turn the power supply on, so that i can multimeter it?

Basically knowing that black is negative. hold the multimeter's black lead to one and test the other wires for 5, 3.3, and 12 volts. AMD Athlonxp 3200+ OC Asus A7N8x-deluxe-E ATI AIW 9600pro 2x WD SATA raptors/raid0 160gb Corsair XMS3200 16x Lite-on DVD 12x DVD-R wireless card used as p

usually black and green turn it on, but colours sometimes vary. pins 14 & 15 are the ones, see here : http://www.duxcw.com/faq/ps/ps4.htm

Computer power supplies are not designed to run or to be tested without them having a load on them, and most will not start up at all when they have no load on them - you are better off to connect them to at least a mboard and then test them. Even if you get instructions about how to do that with no load on them, it is risky to test them without a load on them. You probably don't need a multimeter if you have it connected to a mboard - the mboard likely has a hardware monitoring feature and you can go into the bios Setup pages and look at the most important current readings of voltages put out by the powerr supply. There are tests you can do and symptoms you can check for with and without the power supply being on, or you can try the mboard with another power supply. See response 4 in this: http://www.computing.net/hardware/w... You have not provided enough info about your hardware. You could have an AT power supply if you have an old copmputer, or an ATX power supply - their wiring is different; a standard wired or a proprietary wired power supply of either type - their wiring is different. Most power supplies we get inquiries about are a standard PS/2 physical size and are wired standard ATX. If you have a mboard this power supply was connected to, connect it to that and see the above link. If the computer will not boot when you do that, see the above link.

The best test is to connect to a motherboard and see if everything works.
