300w Power Supply question

[Hamish]

I just got a new case for my computer at a computer show, and I get a warning message now when booting up about the -5v lead. it's running at -6.02 volts. As i upgraded from a 235w to a 300w P.S. i don' know if this is unusual for the Power Supply or not. Any one got any advice? I've been running it for a week now with no unusual lock-ups or anything burning up, so it seems fine. Am i going to burn up the MB and CPU this way?

thanks

Hamish!

A little too much power wont hurt ya as long as it is going to a place that can handel it,
Im running an 800 Athalon and I am SUPPOSED to have a 300w power supply but I use a 250 and i have never had any problems, my point is that these things are tougher than they let on, im sure your well within operating peramiters.

That negative 5 volt lead *may* not even be used for anything in your system.  I have a monitoring utility on my system and I have -5 and -12 monitoring disabled for that very reason.  Most powersupplies will show a higher voltage (higher in magnitude would be a better term) with no load applied.  This reading doesn't seem too far beyond normal regardless.  The *CRITICAL* voltages are the Vcore (between 1.5 and 3V depending on cpu type and speed), +3v, +5v, and also to a lesser extent +12v.  You do not want any fluctuations (<+-.05 v or so) on the vcore and I'd only allow minor changes on the others as well.
