My system is 3 months old , Motherboard is a Asus ROG Strix x870e and PSU is a beQuite 13 Pro 1600W . When I hit power button on my Crosshair 5000 case it does nothing some times when I put it to sleep no Boot only happens every now an then . Power Supply is connected to a power strip . I unplug the power and wait till all lights are gone and plug it back and boots up just find the last Q code was 00 when it didn't boot . I unplug it from the power strip just now just in case the power strip was not strong enough for 1600w I plug direct to the outlet and see if that's what it was. Any other thing to look at .
I connected the power cord to the outlet {Before my system I switch my outlet to a 15a Commercial outlet} and today I hit my power button and no boot ??? Q code on my motherboard 00 . I unplug it , waited and re plug and started up normal ???
Check your switch. I just had to replace one but it's a 23 year old Aluminum Black Lian-Li. Your motherboard has a switch on it for START. You have to open the case. Consult your manual. Good Luck.
