Don't tell me to use a PSU tester, I'm not spending $30 and waiting 5 days for something I can do with the DVOM I have already.


I need instructions, which lines to test and what they should read, etc. with 20+4 (24) pin.

Thanks.
 
Black wires are ground. Yellow is +12V, red is +5V, orange is +3.3V, purple is +5VSB, blue is -12V (you don't need to bother with it), and green is PS_ON. Connect the PSU to the wall and leave the switch in the off position. Use something conductive like a piece of wire or a metal paper clip and connect the PS_ON wire to one of the grounds. Flip the switch and the PSU should start up. Then you can measure each of the voltages. They should all be within 5% of their nominal values, which means that the +12V should be between 11.4V and 12.6V, +5V and +5VSB should be between 4.75V and 5.25V, and +3.3V should be between 3.135V and 3.465V.
