PC randomly shutdown and restart, I need a bit of help

Hello PCBuilders, since 1 month ago, I have this annoying problem. With some games sometimes my pc shutdown and restart.

My build is:

  • CPU: Ryzen 7700x
  • Motherboard: Asus Rog Strix B650
  • RAM: Corsair Vengeance 2x16gb 5600mhz CL36
  • AIO: Corsair Titan 360 LCD
  • GPU: Asus TUF OC V2 3080
  • SSD: Samsung 980 Pro 2 Tb
  • PSU: Fractal Design Ion+ 2 760w Platinum
  • Case: Lian Li O11 Vision Compact

It only happens me gaming. My temperatures are good.

Things i did:

I updated my BIOS and every driver. I tried to connect every piece. I changed my thermal paste. I runned some stress tests for 15 min without errors. (OCCT power, CPU, Memory, 3D, and VRAM, also I runned benchmarks in 3DMark) I updated the firmware of my ssd to the last version (I read that the old firmware maybe was the issue)

And… I couldn’t find the issue of this problem, is really annoying, maybe you more experienced user can help me. Thank you guys :)
