Pc restarts when Gpu is put under load

[sahil illyas]

Hello ,
My pc is almost 1 year old , it was working fine for the first 3 months after that problem started , when I play games like Witcher 3 , far cry 4 etc my pc turns off and restarts within 10 sec after starting the game and same happens when I run furmark so I replaced my graphics card which was gtx 660 the pc restarts when the temperature of the GPU is almost 70-75 c , then I bought a gtx760 and faced the same issue , so I took my pc to a service centre nearby and they said I have a faulty motherboard , and I bought a new motherboard also , still then the problem exists , the restarting occurs when there's load on Gpu

My specs are
Amd fx8320 (hyper 212x )
Gigabyte 970 gaming motherboard
Hyper x fury 8 gb ram
Corsair vs 550 psu
Asus gtx 760 Gpu

Waiting for you help !
Thanks

If anything, the problem is in your PSU. Corsair VS is a low quality tier 4 PSU. If you can, test with a better one.

Use this list for reference; get something from tier 1 or 2 if possible - and if your budget is *really* tight, you can get something from tier 3. Avoid others.

"Corsair vs 550 psu"

There's your problem, I'd be willing to wager on it.

Corsair THEMSELVES say to not use this power supply with any sort of gaming spec PC. It is designed solely for light office use and web browsing.

If your PC is shutting off under load and you have ruled out temperature issues, it is because your system isn't being fed the power it needs.

And please, OP, in the future avoid that "pc service centre" by all means, as they clearly showed incompetence by not even suspecting the PSU. They even made you switch the mobo. Unbelievable.
