The default power limit is 253 watts on the 14900K/KF. Since I have good temperatures, I wanted to raise this value, but even 270watts causes instability. I know a lot of people seem to hate XTU but when running it, it recommends 450watts. Since I’m no where near the XTU recommended value, I don’t understand why this would create instability.

- BeQuiet Dark Power 1kw
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.
So this sounds more like unstable voltages, as I would experience this when trying to undervolt or overclock without adjusting voltages accordingly. I would advise to not only set bios to defaults, but also ensure you have things like multi core enhancement disabled which might be turned on be default. Also enable turbo limits as intel por/default 253w. If you see improvements with this, it might at least rule out you having a faulty cpu/pins
