hello,
does anyone know what this rail does?
is this fatal to any one of my components?

btw i am using a generic 350w running a 2400 35w mobile (IQYHA) @ 2.4ghz with 1.7vcore and running 2.85vdimm into my ram. i have a cd-rw, a DVD-ROM, a 60gb 7200 HDD, a radeon 9800pro and an nf7-s.

thx

It supplies the voltage to the CPU and IDE devices (CD, DVD, HD)

Yes. anything over 13 is excessive and will eventually cause one or all
of the above to fail.

How are you measuring the VOLTAGE (Motherboard monitor, multimeter, etc..)?

I see that kind of variance all the time.

Also I'm 90% sure that the -12v rail is defunct and is not used by anything.

The -12V rail was used for old serial ports. Modern RS232 chips can internally generate positive and negative voltages from a 5V supply. Don't worry about it.
