What's wrong? GPU or PSU?

[CandyCake]

Hi, last time I've bought new GPU, MSi R9 390. Since I installed it I have some problems but i think it's something with my PSU. For example, when I play Fallout 4 I have FPS drops plus some artefacts on my screen, like black pixels snow, something like an old movie effect. The next thing is, when I play Armored Warfare, my settings on default was ULTRA, but when i entered the game I had sth around 25-40FPS and my PSU was hot like hell. So what do you think? Is it the PSU or damaged GPU?

My PC specs:
- MSI 970 gaming motherboard
- CPU AMD FX-8350
- MSi R9 390
- 8GB RAM 1866Mhz DDR3 Kingston HyperX
- DVD Player
- HDD WD Green WD10EZRX 1.0TB
- 3 x 15cm PC case fans
- Cooler: Asus Silent Knight AL
- Power Supply : TACENS RADIX VI 750 (Total 750W)

I did Armored Warfare test again. I had fps drops and after 3 minutes my game crashed, and there was Windows info, that GPU driver has crashed but launched again fine. All components temperatures are OK, but I can't chceck the PSU temp. CPU 72C max, GPU 70C max.

Sounds like the GPU but if the PSU is getting hot it's the PSU. I would recommend a better PSU. Try a corsair CX750:

Should I buy PSU with more W? like 850W or 1000W?

Do not ever buy a CX as an upgrade. Refer to tiers 1 and 2 of this list to get a good PSU: http://linustechtips.com/main/topic/406160-psu-ranking-and-tiers/ Also, 550W is fine for that system. Just saying your current one is rather... shit, too.

sooo, if 550W is enough, that means PSU is bad quality?

The one you currently have is terrible. And so are any of the CX series from Corsair.

But the question is, is it sure that it's PSU fault? It's only heating up in one game.
