Shortly after receiving this EVGA 650W PSU, I have been having issues with the computer turning off and not being able to turn back on unless I flip the switch on the back of the power supply. The power button on the PC continues to illuminate, but does not turn off the computer. I have updated to windows 11 and thought that was the problem so I downgraded with a fresh install of windows 10 pro. This did not fix the issue. I reinstalled all the drivers of my graphics card, my chipset, etc. And none of this helped either. Looking in the event viewer for when the shut down happens, the only event is there was an unplanned shut down with an event code of 41. This leads me to believe that due to a loss of power or fluctuation of voltage that the power supply is the culprit. Especially because this was the only hardware change made since these issues have started. It seems that the shut downs only have happened on steam games so far, but I assume that is just because of the higher stress that video games put on the PSU and other components.
I have all my speeds at stock speed for RAM, CPU, and GPU, so nothing is overclocked at the moment. I have ran a stress test on OCCT for approximately 20 minutes straight and no shutdown occurred. I have checked voltage rails in the BIOS and it all appears normal with minimum fluctuation. I am at a loss, but the PSU is the only hardware change that was made recently and I had no problems prior to this.
