1. Power Supply (PSU) – Even 850W can be faulty. Make sure all cables (24-pin, 8-pin CPU, GPU) are properly connected. If possible, test with a different high-quality PSU.
2. RAM – Faulty RAM can cause sudden shutdowns without a blue screen. Test with one stick at a time and run MemTest86 to check stability.
3. BIOS / CPU Settings – Reset BIOS to default and disable PBO/overclocking temporarily. Ensure VRMs aren’t overheating.
4. GPU – Check that PCIe power connectors are fully seated. GPU temps are fine, but power spikes can still trigger shutdowns.
5. Event Viewer – Look for Kernel-Power Event ID 41 in Windows logs to confirm sudden power loss.
6. Other possibilities – Faulty case power/reset buttons, unstable mains power, or defective motherboard VRMs.

Priority to check: PSU → RAM → BIOS/CPU → GPU → Motherboard.

Now It died in cs2, gpu max usage 100-200W and good temps.
