I have just bought a IS7 mobo and an Antec case with 300W power supply. Everything in PC Health says my voltages are right on, but it only displays the positive voltages. I loaded Sisoft Sandra and it lists my -5V as -3.69V and the -12V as 7-.8V. My question is: Should this be a big deal? I am not sure exactly what uses the negative voltages and the system seems to run perfectly. I am just concerned that this undervoltage may cause long-term damage.

Any help would be appreciated.
