Hello,
My power supply has been working fine for a year plus. I've been using a 1080 with no problems but when I upgraded to the 2080ti all I get is the light on the motherboard to turn on. I thought I was my cables as one vga power cable was new so I tried switching back to my old 1080 but all that turns on is the motherboard. Is there something I am missing? I am completely lost.
