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.

More watts = more amps = more voltage drop from LLC AND higher voltage requirement from increased temperature.
You need to increase the AC load line configuration to counter the increased voltage drop, but first consider whether an additional 2-3% all-core performance is worth the 20-30% higher power required.
