Dead PSU?

Uther · 20 Oct 2013 at 21:12

Just gone to turn my computer on, and its totally dead, no lights, nothing. I suspect the PSU, as I have a usb joystick I usually plug in, that lights up even when the computer is off, and there no lights! Made sure it was turned on at the back, and tried a new lead.
It was working fine yesterday. PSU is a corsair 650. I have heard about a 'paper clip test'?
Whassat then, and is it safe?
And if its dead, recommend a suitable replacement please, system in sig. Not a crazy price either.

Safe to test

Thanks, will try it later! If its knackered what would be a decent replacement?

I was in the same situation as you about 18 months ago. (dead corsair 650 psu) I replaced it with a Seasonic s12II 520 (I didnt need that powerful a psu, the card in in the rig is a 7850 ) G series are supposed to be very good.

OK scratch that, psu is working with the paperclip! Could it be the on/off switch? Its an old case.
I'm hoping its not the mobo...

You can emulate the case switch by touching a small flat headed screwdriver against the power button pins on the header.

Ah, do you have a multimeter to test the power on switch or swop the cables over with the reset switch f your case has one.

Also try a CMOS reset just in case.

OK tried that, no go. Starting to look like the mobo. Any idea what the turnaround is? Its only 6 months old

Try a CMOS as one last go, if this fails then your best bet is to stick a note in the customer service forum

Just tried the CMOS, no dice! So:
Tried another lead
Paper clip trick on the PSU
Reset CMOS
Tested the switch
Dead mobo?
Also, the mobo is 6 months old. Better to RMA to OCUK or Gigabyte?

ok got an rma number from ocuk. Any idea how long the turnaround is on a motherboard rma?

You could just buy a new mobo then sell on the replacement

Yes I think thats what I will do!
