I opened the Motherboard Monitor dashboard the other day and was shocked to see that the +12 V is listed at about 16.3 V!
I have an Asus P4P800 motherboard. I hope that MBM has the wrong sensor and I don't have a messed up PSU. What is the correct sensor for the +12 V rail for this motherboard? Also, what problems can I expect if my PSU is actually running at the voltage listed by MBM?
I'd suggest just installing Asus PC Probe to compare the readings. Pretty sure PC Probe will know which sensor is which. Actually, know it does. It's on cd that came with your board. Pop it in and let it auto run, should be a tab on top called utilities or some such.
