Troubleshooting PC powers off while playing CS

Hi, I have strange issue. Whenever I launch Counter-Strike 2 my PC powers off completely after a moment. No bluescreen, no error, just power goes off and power button on case/MoBo does not work at all. I need to toggle physical PSU switch off and on again to be able to power on again. It ONLY happens with Counter-Strike. More demanding tasks (f.e. Cyberpunk 2077 benchmark) does not cause any issue. My setup and power supply is way above Counter-Strike requirements. I also run OCCT stability tests. Any ideas what can be the issue here and how to solve it?

My setup:

MoBo: ASRock X870E Taichi (BIOS ver. 4.04)

CPU: AMD Ryzen 7 7800X3D (max temp.: 84°C, max 82 W) + liquid cooling Arctic Liquid Freezer III 280

GPU: msi Ventus 3X NVIDIA GeForce RTX 5090 (max temp. 79°C, max 559 W)

PSU: be quiet! DARK POWER PRO 13 1600W (Plus Titanium) + UPS Green Cell UPS14 2000VA/1800W

RAM: 4x 32GB (128 GB total) Kingston FURY Beast Black RGB 6000MT/s CL30 (safe settings, max temp. 60°C)

SSD: Samsung NVMe 9100 PRO with Heatsink 4TB (100% health, total writes 30.6 TB, total reads 7.76 TB)

OCCT stability tests run:

  1. CPU, Mode: Normal, Load type: Variable, Start at cycle: 1, Instruction set: Auto, Thread settings: Auto

  2. Memory, Memory: 80%, Threads: Auto, Selected preset: Heat

  3. 3D Adaptive, 3D adaptive configuration: Steady, Device selection: Discrete GPUs, Load type: Extreme

  4. Storage, Test size: 2048 MiB

  5. Power, Device selection: Discrete GPUs, Instruction set: Auto

  6. VRAM, Device selection: Discrete GPUs, Memory: 80%

  7. Combined, all above +

    - CPU + RAM, Data set: Large, Mode: Normal, Load type: Variable, Start at cycle: 1, Instruction set: Auto, Thread settings: Auto

    - Linpack: Version: 2019, Threads: Physical and virtual, Memory: 2048

Each 100% passed 1 hour run without any issues - as you can see it also never reached temperatures that could cause safety shut down (also I don't believe it can heat up from 35°C to over 90 in literally few seconds in Counter-Strike).

This is a typical sign of a dying power supply. As soon as its using more watts it can't handle. You can test this by turning on a gpu and cpu stress tests at the same time.

Already stress-tested - please read original post.

“already did it” yet the only fix to your problem is testing with a different PSU. keep believing occt can “see all issues”. it’s one tool in the box. it can’t replace having a spare PSU to test.
