After usually around 5 minutes, the computer just shuts off. I thought it was the PSU, so I got a new Dark power 13 1kw PSU and the problem remains. I’m not convinced yet that it’s the hardware but rather something I’m doing wrong in the bios.
After ~12 hours of stress testing, a bios reflash, and OS reinstall, it’s working great now. I don’t know exactly what the problem was, but I can now recreate it if I raise the Turbo Power Limit. Even numbers as low as 270watts (with good temperatures) will cause it to crash exactly like i described in my original post.
Ek nucleus 360. Temps are fine.when underclocked, I had it down to 60c under load and it still crashes.
Other people have said they are having no problem pulling 400 watts from the mobo I have. It’s still possible that my mobo is the issue. I ran hardware info to record a couple times and didn’t see any voltage drops before the crash. Should I expect to?
