I just built this system and I'm having an issue.
CPU and the GPU works fine under load for a good amount of time (game or stress test does not matter) and then suddenly power usage drops dramatically, even while temps are being stable until then
Ive run two tests, one with MS Flight Simulator, ultra settings all maxed out and second with furmark burn-in test to load the GPU + CPU-Z stress test to load the CPU. After 1.5 to 2 hour while CPU is being around 95celsius(junction) and the GPU being around 65celsius - 91(junction) suddenly system starts to stutter, with no sign of classic thermal throttle effects. Also system reboots it self if it does not recover in about 2 to 3 minutes and for some reason when it does reboot while booting (first 2 second) green artifacts occurs. Yes artifacts mostly mean overheating component - as far as i know - but sensors are saying ok
On msfim ive captured those images right after stuttering, suddenly fps drops to one digit numbers;

Same story on GPU furmark+CPU cpu-z synthetic load, first two hour is fine then dramatic fps/point drop, numbers are on the floor. System reboots if it does not recover after some period of time (around 2 min)

Specs
- Gigabyte b650m ds3h - latest bios version f4
- Ryzen 7 7700x CPU
- Rx 6800xt GPU
- 32gb 5200mhz dd5 16x2 kit RAM
- 1tb corsair np600 SSD
- Corsair cx750f 80+ bronze PSU
- Deepcool gammax l240 aio cooler
- Windows 10 22h2
- Mobo might be refurbished, package was not sealed and i got 'new CPU installed' error on first boot
- tried same tests with no peripheral connected
- clean installion of windows is used on each test
- unplugged all case fans and their rgb headers, removed side panels
- 7700x has igpu, so did the same tests and same results except green artifacts as system just shutdowns
- PSU and GPU has coil whine issue
- I've never built PC before but idk if was straight forward. Aio pump is connected to cpufan header, radiator fans are connected to 1/2 sysfan headers, USB, drive activity, power and audio front cables are connected to their respective headers
