Recently I purchased a 2070Super, and after a day my computer quite working. Ethernet light was still on, and peripherals still had lights, but when I tried to press power, light on the GPU and the fans would spin for a half second before they quite. I even tried leaving it unplugged and switched off for 10-15 minutes with no success. I chalked it up to the power supply, or at least I am hoping that is the case. The one I have coming on the way is a Corsair 750M 80+ Bronze. The one I had previously was an EVGA 600W B. Will the Corsair be a good supply to go with? I know it offers enough power, when I checked the amount for an i5-9600k and a 2070Super it clocked at around 430W, so that isn't my issue, I just want to know if my performance will get hit with this power supply?
edit: I guess I should mention, I didn't have light on my mouse, but I did on my USB hub when I talk about peripherals.
