13V on 12?

[Beckinsale]

I installed MBM to check my temps but instead I found out that several voltage indicators don't look too healthy, particularly the 12V feed at 13V. Is this an indication that the PSU is getting overloaded? Or unclean power line? Etc etc?

I think that +/- 10% is OK on the +/-12V buses, so 13V is within spec. I would want to check it with a good DVM before taking MBM's word for it.
