I recently had a PSU failure ( EVGA 750w fully modular). Replaced with EVGA 750w none modular PSU. Before putting all the panels back on I did a test boot to make sure everything was plugged up. As soon as I hit the power button my GPU (EVGA GTX 1060) started arching and smoke. Computer shut itself off. I then noticed that I did not plug the GPu into the new PSU. So I am not sure how it was getting power without being hooked up to the new PSU. Any and all tips/testing is welcome. Thank you in advance
