Random restarts while gaming

[timmons]

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, plenty enough wattage 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.
Not too tech savvy so idea what could be causing this. Any insight would be 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

Did you overclock anything? Sometimes games don't like your overclocks and this may cause crashes or restarts on your PC.

Nope, no overclocks. Computer seems to just black out when trying to run graphically demanding games, sometimes after a couple of minutes..

Try to find a way to make the computer restart consistently. Use something like Prime95 and GPU-Z, or both at the same time. Once you can get it to crash, start removing things one by one and test again. IMO, I would start with the ram. Try running one stick and move it between each slot and test over and over. If it still crashes, try the other stick. After start removing HDD / SSD's, etc...

I had a similar issue and mine was my GPU fault.  Module for power draw was failing and would trigger protections on the PSU, resulting in immediate shutdown (no BSOD).

 

Worth checking out.

Hi guys, apologies for the late response. I tried your advice and ended up testing a different power supply. Turns out the other one was faulty out of the box. Problem solved now, no more random shut downs, thanks again!
