    Depending on which pins you're readin this.
    There are 4 different voltages to a motherboard:
    +5V
    +12V
    -5V
    -12V
    If the voltage you refer to falls under the +12V category, then you're PSU is under delivering.
    If it however falls under the +5V category, then it is clearly over supplying and is most likely to cause some damage.

    Where are you reading your rail voltages from? DMM, BIOS, software? If you're reading off the 20 (and 24) pin ATX connector, green is PS_ON# which is the active low power supply "on" signal. Yellow is typically the +12VDC rail.

    Typically though, the voltage tolerance is about +/- 0.5V assuming you're reading from BIOS or a reliable DMM.

    It's pretty surprising that a system wouldn't shut down, have issues, or flat out result in damaged parts with an undervoltage that great, but *shrug*.

    In any case, 10V is way below where you'd want to be on the +12V line.
