Random power cycles

Laevira · July 24, 2022

Hello lads,

I'm Manuel and I'm starting to become a bit desperate here. I will start with posting my sys specs:

- R9 5900X

- Asus B550-F

- 32GB (4x8) G.Skill Trident Z Neo 3600 CL18

- 2 M.2 SSDs, one EVO 970 and one XPG SX8200 Pro

- Corsair SF 750

- EVGA 2080 FTW3

- Win 11 64

please let me know if anything else is of interest.

I started to get random power cycles a few months back. It started while playing Hunt, then also happened while playing League, browsing, watching videos, you name it. The symptoms are as follows.

- Screen goes dark

- PC starts right up again

- runs normal

What I have done, so far:

- Swapped GPU for a new one (EVGA changed it)

- Swapped PSU for a new one (Corsair changed it)

- Got a new Motherboard (Asus B550-A)

- Swapped the Memory around and ran single or dual sticks only

- Reinstalled Windows, multiple times

- Reinstalled windows on the SSD it hasn't been installed on before

- Checked all the cables and swapped them (with the PSU)

- reseated CPU, GPU and RAM

- Disconnected all RGB

- Updated BIOS to the latest version

- Rolled the GPU drivers back to an older version

- Ran Hunt in Admin mode

Edit:

- changed power cord

- tried another outlet in another room

I am kinda out of ideas. The CPU has been reported to AMD and they opened an RMA and this is sort of the very last thing that I can think of. I was wondering if anybody has had these particular symptoms or has an idea what I could try.

PS: Temps are fine, CPU is on a 5x120 custom loop (normally this cools the GPU, too but I left it on air, for now as it makes troubleshooting easier)

Thanks in advance for any help.

Manuel
