I wonder just how did my 970s destroy my PSU?

[Bhav]

So a couple of days ago I got a pair of gigabyte 970s.

I removed my old MSI Lightning 680 SLI, installed the new 970s, turn on PC.

It barely booted into windows, and switched off. It wouldn't switch on again until I changed my PSU.

The PSU that got slain by a pair of 970s was a 3-4 month old Antec HCP 1300w (I only got it because it was on a today only for £149, and has a 7 year warranty anyway).

Using my previous PSU atm, 850w XFX BE.

Could of been static from you when you where changing the cards but I doubt it.

I've heard of PSUs destroying cards, never the other way around. Can you test the PSU in another system?

I have a corsair carbide air 540 case with the PSU isolated in the back, and I use akasa extension cables running to everything on the motherboard, so all I touched from the PSU were the 4 PCI-E extension cables.

I bought that PSU because I thought it wouldn't die, and also its 94% efficient at 600-700w usage. But now it died. I havnt bothered posting it back for RMA yet, will do next week.

I unplugged everything from the PSU other than the motherboard. The motherboard lights came on, but when I pressed the power button, the CPU fans would only turn on for about 1 second then turn off.

Then I swapped to my old PSU and the motherboard and fans powered on fine, plus everything else after I connected it so it was a dead PSU. And only just purchased in July and supposed to be one of the best and most reliable QQ.

My guess is that it happend random. Nothing to do with the 970

[Bhav]

Hmm, maybe just turning the case onto its side and back up did something, or as you say just random.

I have an RMA number from OCUK, and also need to send an angry Email to Antec.

Always always have a spare PSU. And my XFX BE is still a very nice one for a spare.

When opening up your pc there's always a slim chance of damaging some components. Maybe something got into the psu and damaged it, who knows. I really doubt it was the 970s.
