PC ist restarting while playing games

[Stiffler]

Hello,

recently i have this really annoying problem.

While i am playing EFT (escape from tarkov) my pc is irregular restarting.
First both my monitors are getting black, then the restart.

The logs says this:

I have tried so fixes yet, like this here:

PS:
i have a new gpu since 3 weeks, maybe the gpu itself is the problem(hardware) or the driver(software)

If anybody has an idea, i am thankfully for any help.
Every driver is up to date, and i have installed windows again after the gpu change.

Setup:
b450 tomahawk
32gb corsair
ryzen 7 3700x
rtx 7800 xt phantom gaming
thermaltake Rome 750 w

PS:
I did a prime95 run, with testing the ram and cpu, for 30 min. and the pc did not restartet or died.
Temperature was fine.

How old is the PSU.

Regardless of the age of the PSU, Thermaltake have not made a decent PSU for years and so are on the avoid list and to make matters worse the PSU that you have does not meet the minimum power requirements stipulated by the manufacturer of your GPU, see specs here

32gb corsair

What speed is the RAM and how many sticks of it do you have.

I have found the Problem.
Now that I have connected my GPU to my power supply with two separate cables, everything works.

Thanks for help.

You are welcome but a word of advice, it is cheaper to purchase an appropriate PSU than it is to replace a rather expensive GPU + also having to purchase an appropriate PSU as well, by using a below spec PSU you have already voided the ASRock GPU warranty.
