PS voltage too low?

[Blue4Life]

I purchased an Antec Sonata with 380W TruePower power supply. My computer has only locked up once since I put it together in late november, however I've noticed something that alarms me. My 5V rail seems to measure a constant 5.04V, 12V measures a seemingly constant 11.98V, however the 3.3V has been holding steady at 3.19V. Is this 0.1V discrepency worth worrying about? I'm running MBM5 right now. When I was running the "Intel Active Monitor" software that came with my motherboard, it had alarmed a few times because of lower than usual voltages being detected. Is it possible that I'm overloading my powersupply?

Have you checked your voltage's with a multimeter, mbm reports my 12v rail at 11.9 on my tru480 mult reads 12.0.

No, I haven't. From what location would I measure the voltage?

you can check 5v and 12v on a molex. 5v is red 12v is yellow

Thanks for the info, that sounds easy enough. How would I check the 3.3V?

You can check it at the motherboard connector. I think it was the orange wire.
