Hello. I recently bought 1080ti, i7 8700k processor and Asus strix z370-h gaming motherboard. I was monitoring temperatures and my cpu under heavy load goes only to 70 celzius and gpu never above 70 on 1080p gaming. Only problem is that I am playing on 60 hz monitor and not getting full performance. Like in Battlefield 1 I get average 90 Fps and sometimes drop to 70. After really heav load my pc restarts even with optimal temperatures . I am suspecting that problem is my psu of 530W . Under nvidia specs for my 1080ti , it says my psu is compatible. So question is: do I need to change monitor to 144hz for performance and do I need to buy stronger psu to solve my problem for restarting? Thank you
