Re: Odd Hardware monitoring ?
Don't you have a digital multimeter? My BIOS and software all have different read out, it's safe to say your reading is good from the output as long as it doesn't fall or exceed 10%.
If you can borrow or at least get a multimeter, be it a digital one or an cheap analog and run some test on it. Jump start the PSU with the green and the black wire with a paper clip on the ATX connector, making sure you put some load on the PSU like connect a few CD/DVD ROM to it or else some PSU will shut off after a few second.
