VERY low 12V reading on Antec Neopower 480W

Ive just installed speedfan and this is the reading for the 12v rail:

5.65V

and the -12V rail is -9.07v!

Can this be right? I have a Leadtek K7NCR18D Pro motherboard and the psu happily ran 2 hard drives, 2 optical drives, 3 case fans, a silent boost hsf and a 6800gt agp and an Athlon Xp 2800+ overclocked to 2275Mhz.

When I look in bios or use Leadteks own speedgear utility they do not display the 12v reading *they do show the 3.3v and 5v)

Ive had no system instability, is it just a bad reading or my motherboard doesnt show 12v readings properly?

I find it hard to believe the pc would boot properly, never mind run stably as it has done.

Use a multimeter to verify the voltages.

It may be reading it wrong - have you checked it in the BIOS?

If these readings were correct, your PC wouldn't boot.

Try another program, such as SiSoft Sandra

However, if the in-bios readings are the same as those for Speedfan, then it's the mobo sensors at fault.

Reading is wrong. I have used Antec Neo about 4 months with my FX55@3.2G with no problem. Update your bios maybe solve the problem.

Your comp must be dead by now if those reading are true. Get a multimeter, you'll get right reading.
