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.

When you say instability what does that entail? Clock speeds, temps, power fluctuations, software being unresponsive could all fall under that. Asking as I’ve been running the 14900k with a z690 aorus pro for weeks now with massively varied setups, with xtu ai limits at 450w, bios limits at 253w. With undervolting the even pushing all core to 6.2ghz. Ive put it through 400w load benches and undervolted till it crashed and it keeps chugging along
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.
