My PC unexpectedly power cycles (unsuccessfully) when I am gaming. My PC doesn't seem to be generating a crash report, I have checked my system minidump files and it's empty, I went through my PC properties and made my crash reporting was set up correctly and it was. I had my equipment overclocked, to troubleshoot I reverted back to factory settings and limited running background programs to only essentials. I even upgraded my power supply from 550w to 800w, provided more than enough power from what I have understood

PC SPECS
operating system: Windows 10 64-bit (build 18363)
processor: 9th Gen Intel i9-9900K - 3.6 GHz
Motherboard: ASUS Prime Z390-P (ver. X.0x)
memory: 4x8GB (3000MHz) - 32 GB RAM DDR4
GPU: NVIDIA GeForce RTX 2080 SUPER (8192 MB)
cooling: Liquid cooling; 6- Corsair LL120 fans; 3- CyberPowerPC stock fans
hard drive: 1TB SSD (PCIe) ; 599GB free space
power: 800w power supply


The game it happens most often with is Apex Legends, usually after gaming 10-20min. I have tried multiple video settings with no luck; auto-optimized Nvidia GeForce Experience setting, high settings, and medium settings. I use MSI AfterBurner/Riva Tuner to monitor my RAM usage, CPU temp & usage, GPU temp & usage, and nothing seems out of the ordinary.

MSI AFTERBURNER/RIVA TUNER:
Max I've seen for GPU is 79° C & 70% load.
Max I've seen for CPU is 60° C & 60% load.

I have even tried each of these independently and neither helped:
Underclocking my GPU by about 10%
Removing a panel from my PC case and pointing an external fan at my components
Increasing fan speeds manually at higher temps (>60° C)

Lastly, I did run a GPU stress test with ASUS GPU tweakll (Furmark ROG x64). My PC unsuccessfully power cycled after <5min (4K) test and <20min (1920x1080) test.
I am not too familiar with adequate GPU stress test benchmarks, but I am to understand that this is not a good result for a PC of my caliber?

Can someone please help? I can provide more info, thanks!

Your PSU is being overloaded.
The recommended PSU for RTX 2080 Super is 600-650W.

Get a quality 650W PSU:
Seasonic Focus/Prime and Corsair RM/TX/CX.
I swapped out my 550W PSU for an 800W PSU and I am still having the exact same problem. Is there anything else you recommend?
