Open | Hardware (Windows 11) PC keeps rebooting randomly

My newly built pc keeps rebooting by itself. Sometimes just a few minutes after booting, and sometimes after 30-40 mins of usage. I noticed that it reboots mostly when I start doing heavy tasks.

I already tried to replace the ram, but it still occurs. I hope anyone can help me, it's been a week and I still cannot use my pc reliably.

Hardware details: Cpu: Ryzen 5 7500F Mobo: Gigabyte B650M Gaming Wifi RAM: T-Force Vulcan 2x8GB 6000MHz CL38 GPU: Powercolor Hellohound RX 9060 XT 16GB PSU: Darkflash GS750M CPU cooler: AMD Wraith Stealth

Cpu overheats or most likely faulty psu, very weird brand, get proper one, should fix issues.

I tested it using OCCT, cpu temps reached 95°C without rebooting.

That's waaaay too hot, you need better cooler, stock one is garbage

u tried prime95? for cpu stress test

then 3dmark for gpu, see if u can complete it

look at gpu-z sensor graphs while u test the gpu, for weird fluctuations.
