My computer decided to celebrate Christmas early by dying. It was working a few days ago.

I built myself about a year and a half years ago.

  • GIGABYTE X570 AORUS Ultra
  • AMD Ryzen 9 5900X
  • EVGA RTX 3080 Ti XC3
  • G.SKILL Ripjaws V Series 32GB (2 x 16GB) 288-Pin PC RAM DDR4 3200

Here are the symptoms:

When I turn on power supply, lights come on, fans spin up, USB is powered, eject button on the drives works. Everything seems to be powered except my front panel add-on with more USB.

When I push the power button, nothing happens. No beeps. Nothing on the monitor. No light on the motherboard changes & nothing powers on or off as far as I can tell.

My guess is failed power supply because I don’t think any of this other stuff is supposed to be powered unless the computer is on. My power supply is still the one from the original build back in 2012 & it’s 750W, which I think is borderline for this configuration. Wish I knew for sure before I bought one a new, though. Any ideas?
