I've had a reoccurring problem where my Pc's PSU will Click off like pm pc has been unplugged or how your pc will turn its self off during a Bios update.

It will do this either after a month since the last time or just before Win 11 lock screen or only a few seconds after bushing the power button.

 

Reseating My CPU seems to delay the power crashing by a random amount.

 

I have now changed to an MSI B450 Gaming Pro Carbon. Yet. Mobo this morning. it has not lost power. Yet.

I'm now looking to do a Warranty claim on my mobo. anyone have some help would be nice.

Overheating CPU would do that. A bad motherboard would also. This is also common with underpowered GPUs but I hardly think a 700-750W would struggle with a GTX1080.

 

ADDED: I'm amazed you got Win11 to run on a 2600. Are they even supported for Win11?
