Random restart when gaming not psu i dont think

[rjp9961]

Alright so i got a new psu and gpu theyre a 1080 ti msi’s gaming x and a aerocool project 7 850w psu and after playing some pubg it would just randomaly crash and the only fix ive found so far is to underclock which isnt cool so i was thinking my psu is struggling but after stress testing with no crashes and getting my gpu to draw over 100% power at around 70 c and my i5 6600k to draw about 60w at the same time i really dont know what to do because that wont crash but pubg and just before battlefield 4 restarted also

The restarts alot like i just turned the computer on again like nothing happened no blue screen no freeze just restarts

I have a gtx 1080ti
I5 6600k
Aerocool p7 850w psu
1tb storage
B150m motherboard
8gb ram
All on windows 10 with no overclocking

Sudden restarts with no messages tend to be temperature or power. You can confirm temperature and have, but none of this rules out a faulty PSU. This is the rare Aerocool that is recommendable, on an actual good Andyson platform, but any PSU can be defective and given that you just bought it, a swap to another PSU ought to be pretty painless to rule out a PSU issue. You can go cheaper here, too; there's no reason to have an 850W unless you're going for a multiple-GPU solution.
