Question

Computer randomly restarts while gaming

Mar 10, 2020 1:53PM PDT

Hi, I'm at a total loss here, I hope someone can help me out! -- I have a brand new computer with brand new parts. The computer completely blacks out and restarts itself while gaming. It seems to work fine while not gaming or under heavy load.

Originally I suspected a PSU issue. However, the PSU is a brand new Corsair 750w, which I assumed would be plenty enough for the RTX2080 Super? I tried setting the GPU power intake limit down to 50% in Afterburner, after which I was able to game for a while longer, but ultimately that crashed too. CPU/GPU temperature readings do not exceed 50-60c at crash.
Any insight would be much appreciated!

CPU: i9 9900K 3.6 GHz
GPU: RTX2080 Super (3 fans)
MB: Gigabyte Z390 UD
RAM: 2x16 Klevv 3200 RGB
Cooling: Cooler Master MA620P TUF Gaming
PSU: Corsair 750w Bronze
Others: 1x 500gb M2 WD; 1x 250gb SSD; 4 1TB/2TB HDDs

Linus Tech Tips forums. Why? They have built a lot of i9 machines.

I take it that:
1. The PSU is single rail.
2. The RAM is on the QVL.
3. The BIOS is current and running defaults or what the maker told you to set it to.
4. You didn't cram this into a small case or consider heatsink compound optional and you see the fans working like new.
