I just upgraded my EVGA 500W White power supply to an EVGA 750B Bronze power supply in preparation of my RX Vega graphics card. After the upgrade, my computer keeps turning back on a few seconds after I shut it down.
None of the software solutions online worked, but when I swapped out 750B power supply back to my old 500W power supply, the problem was no longer there. Therefore the problem must have something to do with the new power supply.
Do I have a faulty unit or is there something I might have done wrong?
My computer is a Dell XPS 8910 Special Edition, with i7-6700 and no graphics card at the moment.
