Alright back with more details. First I'm not over clocking anything everything is stalk. I'm also gaming @ 1440p.
Don't think the PSU is the issue and here is my reasoning. I have a UPS with a digital read out of the Wattage load. I ran 3d Mark again just now, this time the 4k extreme test.
NVIDIA GeForce RTX 3080 video card benchmark result - AMD Ryzen 9 5900X,ASUSTeK COMPUTER INC. ROG STRIX X570-I GAMING

AMD Ryzen 9 5900X, NVIDIA GeForce RTX 3080 x 1, 32768 MB, 64-bit Windows 10}
Peak wattage usage with both the monitor "HP OMEN - 27" IPS LED QHD FreeSync & G-Sync Compatible Gaming Monitor" & the PC was 489w for both graphical stress test. I have seen the wattage above 500w when playing Monster hunter world and I continue to play it with no crashing issues.
For the sake of numbers I booted WarZone again to see what the wattage was @ time of fault knowing the main menu is one of the failing locations and not too graphical heavy compared to actual game play the peek wattage was 280-287 idle.....and without fail within 10-15 seconds just sitting @ main menu PC crashed.
