11.584 on the 12V Rail, any improvements possible??

[nvfx]

Well guys....

Here is my sys spec..

AMD64 3000
ASUS K8V SE DLX
Mushkin 512 MB Ram
Gigabyte X800 Pro
Thermaltake WinGo Gaming Tower ( 5 fans + 2 PSU fans + AGP + CPU )

Well my 3.3 V and 5 V rails are very good but the 12 V rail is constant at 11.584 to 11.623.

I wonder if that is harmful or not, though it falls within 5 % error but i previously had a Bad Mobo expereince.

Any means to Mod my Thermaltake 420 Watts PSU to make it cleaner.

I wouldn't trust the readings from your bios too much.
I wound up unnecessarily buying a couple of power supplies going by bios readings.
Right now I am using a power supply in my main rig temporarily and it shows much improved readings on my Abit NF7-M. I pulled it from my son's computer that houses an Abit NF7-S cause the rails were too low and fluctuated. I had the same problem with a Biostar board.

The only thing I trust completely now is a multimeter. (Too bad I have yet to buy one 😱)

Try a voltmeter to verify that. Otherwise try another psu. My guess is the mobo is just reading low.

Definitely check with a voltmeter, though sometimes the tolerance on that line is allowed at +/- 10% (+/-1.2V). In which case that would be fine. The 5 and 3V lines have a +/- 5% tolerance which your measurement is within as well (+/- 0.6V). One would like to see it closer to 12V but...
.bh.

Yup...you're well within tolerance...3.5%. Chill!
