12V Rail Tolerances

[Guest]

I bought a new 500W power supply to replace the 350W i had previously.
The voltage reading using ASUS Probe is 13.312V. I know the tolerances
are supposed to be +/- 10% which should take to at most 13.2V.

Should i have reason to worry? Should i take the supply back to the
vendor?

Forget about any built-in hardware or software monitoring solution for
obtaining accurate voltage readings. If you are really concerned, find a
multimeter somewhere and measure the voltage. I suspect you will find that
the voltage has been over-stated by Asus probe. But if that voltage is
accurate, I'd replace the power supply. -Dave

You're right! Checked with a DMM and the voltages were all within a
+5% range. Why would ASUS Probe give such incorrect figures?
