Might sound like a stupid question but I wonder if anything in a modern computer uses the -5v leg of the power supply and if so, what? Thanks!

Hey Albert,

Sorry for the late reply. Lots of things run on - 5 volts or less. Hell most video cards the military use -15 volts constantly. Lets say you have a video card that shows different figures on a CRT. In order to get the lower half of the CRT negetive voltages are necessary. Hence the X and Y axis like you learned in Math classes.

So to answer your question, the -5 volt line could be for a mouse to travel around your screen. Or for your video card but these days video cards run from .8 vdc to 1.5 vdc.

Hope that helps,

junkdk :thumbsup:

Dear Albert,

No Problem.

If you want to throw around electrons, I'll be your catcher! Helping to stomp out arounous voltage errors since 1993.
