Question PC keeps shutting down and restarting

[LEGENDKMS7]

Every time I run a benchmark, pc would shut down and restart. Surprisingly, I can play a game of CSGO, but when I would go into my inventory, pc will shut down and restart. Event viewer is not telling me anything. I rebuilt my pc a day ago. The only thing that I changed in the bios was enable XMP with boost200s.

Motherboard - Asus Z890 Apex Maximus
CPU - Ultra 285K
GPU - Aurous 5090 ICE OC(Updated drivers before this post with DDU)
Ram - G.SKILL Trident Z5 DDR5 RAM 48GB 8200MT/s CL40-52-52-131 1.35V(Using XMP with Boost200s)(Ran memtest for a couple of hours last night and no errors)
PSU - be quiet! Dark Power Pro 13 1600W
AIO - ASUS ROG RYUYJIN III 360 ARGB Extreme
M.2 - Crucial T705(1 in m.2.1, m.2.2, and one in the dim slot to get 16 lanes for the GPU)

When the PC shuts down does it instantly do so? Kind of like a power outage, but then restarts? What does Event view say is going on shortly before the shutdown? If I had to guess I would say the PSU is having some issue. Check the 12V2x6 connector on the graphics card for melting.

Yes, it instantly shuts off and then restarts. "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." is what event viewer says. I also switched out the connector to another and it is still giving me the same issue. The previous cable does not look melted or damaged but switched it out anyway.

I suspect the PSU is having issues. If you have a known working one I suggest you try it in the PC. You may want to get another one for a test. I suspect the PSU is just faulty. Bequiet! have some great PSU's, everyone makes a dud every once in a while. I would buy a second of the same model if you still prefer them for a test. Can you still return the first one to the retailer for the money back or an exchange?

Ive had this psu for about 2 years, I can get another of the same model, but I won't be able to receive from amazon for weeks.

I would get something that is more available that also is a great 1Kw+ PSU from a retailer you can return it to if need be. I would also start the RMA process with Bequiet! for your current PSU if and when it is determined that it is the issue. Something like this if its available to you.
