PC dead this morning - presumably PSU?

NickTheBiz · 4 Nov 2017 at 09:02

Asus Z170-E
Intel i5-6400 (non-K) @ 4.4Ghz
Kingston Fury Black 8GB (2x4GB) DDR4 PC4-21300C15 2666MHz Dual Channel Kit - Black (HX426C15FBK2/8)
Alpenfohn - Brocken 2
NZXT S340
Corsair CX600M
2 x Samsung 840 Evo 250GB
Geforce GTX 960 4GB GDDR5 OC

Getting a flicker of power but overall nothing. Have disconnected my 1070 and PC seems to spring into life.

So is PSU dead? Is it underpowered?

You got two graphics cards there or what?

Short circuiting graphics card would trigger protections that way.
Or failed card messing with motherboard could cause it to "crash motherboard" stopping boot process.

For single such card 600 watts isn't underpowered, more like the opposite.
But despite of what brand name might suggest that PSU is standard mediocre quality one with cheap C(r)apXon capacitors.
So would anyway put that to replace in few years category if it gets lots of running hours daily.

No, just the one card. Yeah Going to go pick something up shortly.

something daft already!! · 4 Nov 2017 at 10:18

It does seem to exhibit symptoms of failed PSU but the GPU is a spanner in the works and the fault could be there instead. Have you got another card to try?

An old 960?

NickTheBiz · 4 Nov 2017 at 10:22

1070 is only a few weeks old

NickTheBiz · 4 Nov 2017 at 10:28

Everything works with the 960 in it... hmmmm

Ah ha! I had a feeling it might be the GPU. Perhaps though, the PSU isn't quite sending enough power for the 1070 but enough for a 960. I guess the next step would be to try in a friend's PC or start an RMA.

Cheers dude.

GTX 1070 is indeed more power hungrier than GTX960 but difference shouldn't be that high during boot...
And if that difference would be enough PSU would be anyway ready to release "magic smoke".

New PSU installed yesterday, tested ok.

Put 1070 back in... it's toast
