PC Shuts down while gaming, restarts, Sapphire RX-480 nitro+ 8gb doesn't work.

[Dance Commander]

Today while playing hitman my computer shut down and restarted, it's the first time it has ever happend, I thought there was a blackout but my TV was still on.

Anyway the GPU gave no video feedback, the led on the side turns on but nothing else, the fans don't spin (they never spin below 52°C, although I think they are supposed to spin on startup?) the card is connected through an hdmi cable, for a second the tv goes from no signal to black screen to no signal again, I switched the hdmi cable to the motherboard slot to use the onboard graphics (I5 4670) and it gives video feedback, meaning the GPU isn't even recognized as active, I checked the bios it's set to prioritize the PCI slot.

When the PC shut down I couldn't smell any burning plastic from inside, I'm at a loss.

I know it's a long shot and the GPU is probably done but do you have any suggestions?

The PSU is an XFX TS 650

So you just can't get any signal with the GPU anymore? Do you have a spare GPU, or spare system to test the GPU in? If the GPU is indeed the issue, you have to RMA it.

I could be wrong but it sounds to me like the PSU died or killed some of your components. Either that or the mobo/ GPU decided to die on its own.

That's my first suspicious as well. I actually had an XFX PSU do exactly that to me about four years ago. Made a hell of an expensive mess, and taught me a valuable lesson.

Yes could be the psu, possible the fan is gone and parts inside are hot as eff now.
To avoid damage, unglug the psu cables from the mobo, gpu etc.
Also possible, the mainboard capacitor broke off or so.

How old are the parts? Maybe u can make use of the warranty.

The PSU and GPU are less than a year old.

But if it was the PSU that broke down wouldn't the PC not work at all? It works normally with the onboard graphics.

GPU probably died. Get an nvidia gpu next time...

Do you have a spare GPU, PSU, or spare PC?

1. If you have spare GPU, switch them out, and test it out.
2. If you have spare PSU, switch them out, and test it out.
3. If you have spare PC, take GPU out from your system, and put it into the spare PC, and test it out.

If #1 works then it's the GPU issue, if #2 works then it's the PSU, if #3 then it's the PSU.

I. The PSU seems to be ok (xfx is an ok brand for sure) - otherwise your pc would not boot.
II. Looks like your sapphire card died. You could try the card in another pc just to be sure. but in any case just rma it and get replacement!

good luck

Can't do anything of the sort until tomorrow

Could be the port too. Wouldn't be the first time I've seen one of the GPU ports die even though the GPU itself is fairly new.

[Dance Commander]

In case I have to RMA the card, should I RMA to amazon? I bought it directly from Amazon.fr and I heard EU warranty is dependant on the reseller and not manufacturer.

[Bad 💀 Motha]

If Amazon will replace it, sure why not.

Amazon > My Account > My Orders > Item > Replace

I tried the other PCIe slot, doesn't work.

The culprit must be either the gpu or the psu miraculously burned the 12v rails and nothing else and still works.

Can't do that from there, item is 8 months old, obviously still withing warranty

I think he meant video output ports on the gpu. Most gpu's have a few hdmi/displayport/dvi ports. The one you were using might have died, try a different one.

Thing is the video feed defaults from the onboard graphics, so it wouldn't change, plus on device manager the gpu doesn't result connected.
