Slightly low on the 12 volts

[Lemon law]

While I am more disturbed about my CPU temperatures, various monitoring applications showed my 12 volt rail voltages at 11.8 to 11.9 volts. And I certainly am not pulling any heavy loads, one HDD, one Optical drive, one floppy drive, no case lights, so I should not be browning out under load. ( all other rail voltages show north of nominal voltages )

Well yesterday I stuck a VOM into a molex connector, and got a reading of 11.9 volts on the 12 volts that could fluctuate back and forth between 11.8 to 11.9 volts with the VOM reading about .1 volts higher than the monitoring software. But I see no evidence of dropping voltage under conditions of PC load so I do not think my power supply is suffering from brown out from too much load.

I also note another PC I have with a better power supply always shows 12 volt voltage a few tenths of a volts above 12 volts.

So -----

A. Is the slightly sub 12 volt rail voltage something I should worry about?

B. Could the slightly sub 12 volts cause the CPU temperature monitoring to show incorrect readings?

Most people would kill for a 11.9V rail.

ATX12V specification allows for 5% +/-. So even 11.6V is acceptable. Be happy you're at 11.9V.

Thank you for the prompt response jonnyGURU, so as long as it does not in any way for fox my CPU temperature monitoring either, its nothing to worry about.
