3 months ago I upgraded my motherboard, CPU and ram. Ran stable with my old GPU still installed. A week ago I upgraded my GPU to a new Sapphire Nitro+ 5700 XT and now experience sudden power loss while under heavy loads. After playing a round of PUBG, returning to the lobby, then starting a new game my whole system looses power. The PC runs fine and idle and under low loads.
I was able to replicate this using OCCT stress testing. Ran a power stress test for 20 mins, all voltages seemed okay, temps peaked at 78 degrees for CPU and 71 degrees GPU. Stopped the test, waited 2 minutes then started another stress test and the whole system powered down again.
I am running stock clocks and have updated all drivers as well as my BIOS. Can I get some confirmation this is most likely PSU issue? It's now my oldest component (5+ years old at this point)
Specs;
Ryzen 7 3700x
Stock Wraith Prism cooler
Gigabyte Aorus Ultra X570
2 x 16GB 3200 MHz Corsair Vengence LPX
Sapphire 5700 XT Nitro+
EVGA 750W G2
1TB Samsung EVO 860 SSD
