PSU killed GPU or not?

[kentstin]

Hello,
So, I was running a heaven benchmark test at stock speeds for my r9 fury nitro and a little over half way through, my computer just shut off. I have a AX 860 PSU. I decided to flip the switch on the PSU to off to see what would happen later. I came back to my pc and flipped the switch and pressed the power button. Nothing turned on with no sign of power received. I decided to clear cmos just to see and reseat everything including the connectors. Turned the PSU to on and pressed the power button and nothing. I borrowed a spare gt 710 from a friend. I replaced that with my fury and it turned on an booted into windows. I put the fury back in and tried to power the system on and nothing happened. No signs of power was on the board. I tried once more to see if it would at least turn on and it did, but with a spark flying out of the GPU. Obviously I shut it down fast. I changed the psu to an old AX 850 to check on everything with the 710 installed and everything seems to be okay. Could the AX 860 have taken my GPU out, or could the gpu have died on its own? I think it’s the PSU’s fault because its two and a half years older than the GPU, but I’m curious to see what you think. I've had the PSU for four years and the GPU for a year and a half.

Age is not the only factor when it comes to determining failure of components. Power supplies do last a fair while, and even my Enermax unit I bought in 2012 is still going strong running 24/7 in a server. The video card could've failed on its own with a defect in one of its components(even the PCB itself) that only manifested now.

Ah man. So I'm guessing the GPU shot out a spark (probably a hot metal ember since there is a metal piece on my desk) because of that defect? I've never seen a spark come out of a component so that why I thought it might have been the PSU.

If the video card had a defect, yeah. I've had a 660 Ti fail under a Folding@home load - one of the tiny capacitors for the MOSFETs blew up. Is your R9 Fury Nitro under some kind of warranty still?

I wouldn't suspect that the PSU killed it. It may have just died as some electronics inevitably do. I'd try to RMA it.

I'll give the RMA a go and see what happens. I'll post an update if something happens. Thanks for the help and suggestions.
