i think i blew my power supply?

[Kyle Giesbrecht]

So i was sitting at the computer and went to make a drink. Came back and computer was off. Still had power to the monitor but tried resetting the power bar. Nothing. Dead.

Tried replacing the power cord to a new one. Still dead.

Now if I flip the switch on the psu and then try turning the computer on ill get a one second flash of lights then back to dead. To get the lights on for a second I have to flip the switch off then back on each time.

Opened it up. No real dust. Psu wasn't hot, nothing else had any residual heat.. No other ideas on what it might be. Dont have any other psu to try,

Computer has ran without a hitch for two years.


No sparks from anything. The power supply is a:

Seasonic Model SS-520GB

Light sparks coming from the power supply sounds like a clear indication that it's dead. I'd replace the unit and hope it didn't damage any other components. Go for a quality PSU from XFX, Seasonic, Antec.

What lights are turning on? Regardless though, if some system lights turn on, your PSU is still supplying power. The issue might still lie with the PSU but lights turning on means that it isn't necessarily 'blown'. Please let us know which PSU it is; if it is a high quality one, odds are even less that it blew.

By lights I mean the power light and the light on one of the fans. They blink on then off immediately. Less than a second.

Looks like I misunderstood. The power supply in question is a good one but that's strange symptoms you've got there but even if it is a good unit, any electronics can fail.

I tried shorting out the power supply like seasonic says and switched the power supply on. Fan didn't start at all.
