As I said, testing the power suplly by jumping the wires only proves the fan works.
>When a computer starts , is "booting up" , a power supply is under the heaviest load.
The only way to test a power supply properly is under a full load .
If you hook the power supply to the motherboard & everything else like it's supposed to be , then turn on the unit, & the power supply shuts off more then likely it is bad.
If you turn the uni8t on & all that happens , period, is either nothing or just the fans spin the motherboard is probably bad.
You aren't going to determine what the problem is with a bent paperclip though.
My suggestion is if you don't have any spare parts to work with [I understand most people don't] take the power supply to a shop & have it tested.
