What do all these PSU properties mean?

I have an NF7-S and was looking at the Winbond Hardware Doctor and my -12V line has a low limit of -13.01 and a high limit of -11.04 and the actual kept going above -13.01 so it kept beeping. I adjusted the limit to -13.09 so that it would stop beeping, but I'm not sure what these things do. Could anyone explain?

    ...convert your 120V (or 240V) to a 5V and a 12V feed. If you look at the molex connectors like you use to power a hard drive you'll notice two black wires, a red wire, and a yellow wire.
    The yellow wire is the 12V +, the black wire nearest it is the 12V -.
    The red wire is the 5V + and the black wire nearest it is the 5V - .

    Your Winbond Hardware Doctor just monitors those voltages to make sure that they are within the proper range. If your 12V dropped to 3V you could damage other hardware (like the hard drive, cdrom, etc). The alarm is to let you know if something is going whacko.

    When you raised it by .08V you were basically telling it not to worry if the voltage was a smidgen higher than the default setting thought was out of range. .08V is not enough to worry about - it's probably within the margin of error for the sensor.

    There might be an updated version of the Winbond monitor which is more accurate for your board, check with the MB vendor.
