Question I need help fixing the PC powering-off due to the GPU ?

[SoraKyo]

last year I got an upgrade for my pc from a GTX 1650 to an RTX 2070 Super, with that I also upgraded my PSU from a 250-watt to a 600-watt PSU (be quiet! T380697 System Power 9 600W, 80 PLUS Bronze, power supply, Black). It was fine for the first few months of heavy and light gaming but out of nowhere, my pc turned off and then after around 5 minutes it automatically turns back on, this issue will repeat itself around 10 times in a row I checked Event View and I had multiple kernel-power events 41. This problem stopped for a year and came back last week when at random my pc will power off even if it was idle in windows with the same kernel-power event 41 problem and didn't stop, I checked everything online but nothing fixed it so I changed my GPU for the 2070 super to the 1650 with the same PSU and the problem went away. So right now I do not know if its a problem with my 2070 Super or my PSU

My thought is that the 600 W PSU is not able to (or no longer able to) fulfill the system's power demands.

Especially at some peak requirements.

PSU ay be defective in some manner and/or degraded much faster than normal. Now at or nearing its' designed in EOL (End of Life). All the more so if frequently required to provide upper end and peak wattages while gaming.

Not with the immediate intent to purchase a new PSU.

Simply work through a few of the calculators to determine the appropriate wattage PSU for the PC.

Also do your own manual calculations. If a compent provides a wattage range then use the high end wattage value in the total.

Do comparisons between the GPUs in question.

Yup, replace the PSU. This is not a PSU that was ever equipped to run high-end GPUs. Now, the RTX 2070 is no longer a high-end GPU, but it still has the needs of one and needs to be powered appropriately.

It's no different than if you buy a cheap 20-year-old Bentley. The car may be cheap, but you'll still have the extremely high repair costs.

While it's uncertain that the PSU is at fault, the PSU needs to be ruled out and since you're using an inappropriate PSU for an RTX 2070, replacing it is the obvious next step. You needed a new PSU whether or not the PSU is causing this specific problem.
