When I game with hardware monitor running I've noticed my 650 watt psu's 12 volt reading drops to 11.53 volts at times and the highest it reads is 11.97 volts. It has been like this almost since new which is 4 years ago. It's a LSP Ultra psu.The reason I'm asking about this now is sometimes when I oc only to 4.3 the pc goes into a no boot mode (fans start then stop but wont enter bios until I reset cmos ). Any opinions on this or could it be another problem ???
