Hi there! Long time lurker.
I have an EVGA 2080ti XC Ultra that I am trying to overclock in MSI Afterburner beyond what the "autoOC" determines. The issue is my system shuts down when I overclock beyond autoOC, which I suspect is a PSU issue, BUT I can't figure out why a Corsair 850HX (80 Platinum Rating) is insufficient for this.
The "autoOC" gave me a +120 core and I found +750 on Memory Clock to be stable over 4+ hours of 4k gaming in Red Dead Redemption 2. In MSI Afterburner, power limit is 100% on this setup, no stability issues whatsoever.
When I bump the Power limit to 130% and crank the core to +131 and mem to 765, system shuts down. Need to cycle the PSU to bring it back to life.
Relevant system specs:
Ryzen 9 3900X set to "autoOC" in Ryzen Master
32GB DDR4-3200 RAM (16x2) XMP2.0 stock profile
EVGA 2080ti XC Ultra
Corsair 850HX Platinum
The PSU is a holdover from my old build which powered an i7-4770K / R9 290 OC combo and never encountered any such issues. is the 2080ti / 3900X combo more power hungry than my previous build? Both GPUs are rated for 250W TDP so even with an overclock I can't imagine why the 2080ti would be worse in that aspect.
Any help would be appreciated. Thanks!

For beginners, using Evga Pasco software is the best choice when overclocking the GPU directly. My preferred option is GPU-Z. You can also check the discussion on evga forums and create a thread for assistance.
