Troubleshoot a Powersupply?

post #1 of 4
Thread Starter 
okay, I woke up this morning and my computer isn't powering on at all. Pressing the powerbutton is giving me nothing.

The mobo has a green light to notify when the mobo is getting power and instead of it glowing nice and steady it seems to be flickering. I'm thinking something is wrong with my powersupply. Is there some way I can test my powersupply, say, with a multimeter or something?

Unhook everything from the power supply, then take the 24 pin main connector and bridge the green PS_ON wire with a black ground wire. Then hit the switch on the back of the powersupply and see if it comes on.

Thanks for reply. I shorted those pins and the psu spun up fine. This means it's got to be the motherboard.

No problem, if you really want to be sure your PSU is ok you can tap the 12 volt line on a molex connector while the PU is running and make sure it reads at around 12 volts. Or if you dont have a multimeter plug in a fan and see if it spins up.
