Using a GA 7VT600 1394 MOBO. Thermaltake PSU. (480W Butterfly). Using
sisoftware plus other monitoring software to watch voltage & temps. (New
computer-temps are fine). The -12V & -5V are low. -4V to -6V for
the -12. -.03V to -3.0V for the -5V. Can these low voltages cause problems
such as a reboot or lose of video? I checked my other machines and these
voltages are almost right on the money? Bad PSU?? Also have a query into
thermaltake asking if it's normal. (I'm sure it's not????)

TIA
Rudy

Do not concern yourself with the -12V and the -5V lines, as they are not
being used.

The +12V, +5V, +3.3V and Vcore should all be within 10% of nominal. A decent
PSU can keep them within 5%, under load.
