Biggest issue is that a 500w PSU is barely enough for your hardware and that assumes perfect effeciency. Though I’m not sure it would be pulling that much power during post.

 

if the mouse and keeb don’t respond, there’s likely something wrong with your USB ports. Though two failing at once is unlikely.

 

 

other causes could be bad boot device. Damage to usb ports or controller.

 

first this? Reset the bios. Try different usb ports (if wireless, plug them in).
