I created two very similar PC configurations in 2023 (the only variation lies with the GPU):
1)
ASUS ROG STRIX B760-F GAMING WIFI
2)
Intel Core i5-13400
3)
WD_BLACK SN770 NVMe SSD 2 TB High-Performance NVMe SSD, Gaming, PCIe Gen4, M.2 2280
4)
Corsair Vengeance RGB 32GB DDR5 RAM with 2 Modules (2x16GB) and Speed 5200 for Desktop (CMH32GX5M2B5200C40)
5)
Corsair RM850x Shift 850W Full Modular 80 Plus Gold PC PSU
6)
Noctua NH-U12S chromax.black
7) GPU Asus GeForce RTX 4070 12GB GDDR6X ProArt OC Edition Graphics Card
and Gigabyte GeForce RTX 4070 12GB GDDR6X Windforce OC
8) CORSAIR iCUE 4000X RGB Mid-Tower ATX
9) Windows 11 Pro; all updates applied.
10) ESET Smart Security Premium installed.
From December 2024 onward, both systems began shutting down intermittently under load or without load. Once shut down, they wouldn’t power back up. After some time, restarting was possible.

What actions have been taken so far:
Q-LED displayed issues with the graphics card and boot process on both units. Both BIOS updates and Intel ME updates were applied, yet the Q-LED problem persists.
Additionally, CPU tests via Intel Processor Diagnostic Tool showed no faults.

Despite these checks, the “auto power off and then can’t restart” issue remains unresolved.
Any suggestions on how to resolve this further?
Thank you ahead of time.

These are signs that PSU protections are activating. Lower the GPU power target and apply MSI afterburner. Scan your system for cryptomalware using Malwarebytes Antimalware.

Thank you for your quick response.
For the MSI afterburner, I attempted to launch without a GPU and encountered the same issue.
Re Malwarebytes Antimalware will try it.
The main challenge is that I can't start the system and have to wait several hours. Any suggestions on how to resolve this? My PSU seems quite capable.

The PSU is extremely reliable. That doesn't imply it's not broken, but having two identical units failing at the same time seems unusual and unlikely. Did you reset the CMOS after the BIOS update? This could be useful. Your GPU isn't a high-power device; it uses only 200w when operating at full capacity. It's quite efficient. You may want to inspect all internal wiring and think about swapping some components, as the PSU might activate its overprotection feature if just one cable is damaged.

Verify CPU and GPU temperatures.
Unplug the power cord from the PSU to the wall.
The PSU protection state should reset.
Inspect the PSU fan; it might be defective and the PSU is overheating.
This could lead to a PSU shutdown.

Thank you for your feedback!
CMOS has been verified.
I'll examine the cables. It could be the housing LED or extra fans that are the issue—I'll attempt to separate them.

Updates on the situation and actions taken:
1) I inspected the PSUs (Corsair RM850x Shift 850W Full Modular 80 Plus Gold PC PSU).
On 2 computers that had problems, they functioned correctly with both PSUs.
Checking methods:
a) I connected my third computer to the PSUs of those 2 problematic machines. The third computer worked without issues.
b) When connecting two problematic computers to a 3,000W PSU, none powered on—both failed to start.
Thus, the issue isn’t with the PSUs themselves, but possibly with other components in those 2 computers.
2) I tested 2 GPUs with my third computer: they operated normally, maintaining temperatures between 40–50°C.
Questions remain about troubleshooting steps—should I inspect wires, check the motherboard, or explore further?
