Whats broken

Hi started having warning on Asus suite of over voltage on 3.3 volts

Tried removing Asus suite as its known to be glitchy and received a total PC shutdown on reboot was given explanation PC shutdown due to overvoltage

Question is it Power supply or Motherboard related Aida software reports my 3.3v is running steady at 3.5v

Motherboard Asus Z77 Sabertooth (year old)
Power Supply Corsair AX860 (2 months old)

Thanks for any advice

3.5v is out of spec. Max is 3.465v. The only way to properly test it is with a multimeter though.

Thanks for the reply but which would be at fault Mobo or PSU

Going by your readings the psu is delivering voltages that are out of spec. The only way to be sure is to test with a multimeter. If you haven't got one they are around a tenner on the bay.

Ignore it's fine, some motherboards report slightly high or slightly low sometimes. Also the PSU is new so still breaking in and in time will slowly show slightly lower voltages as it ages.

What is the rest of your system spec ?

Thanks guys for peace of mind have ordered a multi meter to check it out.

Good move. It's all very well to be told to ignore it but if it is putting out unstable voltages it could damage your components. A multimeter is the only way to be sure. Admiral Huddy did a excellent guide on how to do it here. It's a good idea to do the tests with the psu idling and then at load. My old one was fine at idle but out of spec once loaded.
