Voltage readings worrying me
well I've recently been noticing when my cpu is under full load...and doing other things...smart gaurdian shows my +12V readings sometimes drops as much as .25V on the rail. and it usually stays at 11.96 to .89 so I'm a bit worried....so is this a problem or and I just freaking out to easily herE?

A 3% varation is normal and up to 5% is acceptable.

You are well within ATX specs,+/- 5% with 11.4V being the minimum.

Not to highjack his thread but i have the same issue with my Antec tpII 550w and using Smart Guardian on my DFI board.. All voltages are rock solid but the +12v rail. It jumps from 11.7 to 11.96 to 11.83 constantly and every so often causes my pc to shut down.. Those power supplies are known for weak +12v rails so im dumping it and picking up an OCZ 700w GameXtreme wednesday! Even though the voltages fluctuations are within spec they still cause issues with a picky board like the DFI Expert..

Software sucks for measuring voltages through the PSU. (12v, 5v, etc.)
Pull out your multimeter and read yourself.

FYI, having a battery back up helps to provide clean stable power to the PS

yeah, if you want to be sure, get a multi meter.
