GPU Question, Failing PSU?

[CSchmied986]

I've been having some issues while gaming and was wondering if anyone may have some insight? While playing MXB, or several other games, I seem to have FPS problems, and taking setting from max to min really doesn't help much, and sometimes my PC cuts power and reboots. I am currently running an AMD R9 390 8GB GPU and have 900watt PSU. While gaming runs pretty cool (50c-60c), and all my other temps are in low ranges, which I am guessing my PC is not running very hard? Could these issues and random system crashes be due to a failing PSU, or anything else? Thanks!

There are variou sstability test around in order to stress-test your CPU, GPU and even both at the same time (which of course will also stress-test your PSU).

Prime95 for the CPU, furmark fr the GPU is the popular combo.

Running a memory diagnostic tool might be worth a shot?

Thanks! Ran the GPU test and it did well for about 3 minutes and got to 84c and then crashed. Guessing PSU?

84C should not crash your GPU. It should be able to handle up to 100C. What brand/model is your PSU? And how old is it?

Edit: I've just read the card has been spec'd to run "safe" up to 95C. Not sure, but IMO just above that it should start throttling (underclocking), not shutting your PC down any time soon.

If it's just instantly going off like you've hit the reset button then i'd bet on the PSU, it's also the cheapest thing to swap out. Had this myself and seen it loads.

Got a new 900w PSU, seems to have fixed it (so far)!
