PSU Voltages

[Squirrely]

As I was sneaking around in Everest a bit ago, I noticed the sensor buttons under the Computer drop down. Turns out it has a display of all my PSU's voltages. The thing is that the voltage values seem to not be that close to their intended values:

+3.3v : 3.23v
+5v : 5.13v-5.16v
+12v : 12.37v

I know that the voltages can fluctuate a bit, no psu is perfect, but by this much?

I currently have a Thermaltake 420w TR2. (http://thermaltakeusa.com/product/Power/TR2power/w006162/w006162.asp) (Its a bit loud too :shadedshu )

My system specs are in my profile. I have recently overclocked my 8600gts, so that's a bit more power draw there also.

The eXtreme PSU Calculator says I need 284w (20% capacitor aging) (http://www.extreme.outervision.com/PSUEngine)

I got my PSU about 1.5-2 years ago.

Do you think I need to get a new PSU? Also is it normal to see the voltages fluctuate this much? I also heard Everest can be a bit inaccurate in places, so is this maybe the problem also?

Thanks.

There is also +/- 5% to figure in as well.

Those all seem like they could be actual voltages. Also it can be double checked in the voltages section of your BIOS.

I'll check in my BIOS, let me get the numbers from there.

Edit:

Just checked, they are:

+3.3v : 3.43v
+5v : 5.13v
+12v : 12.37v

So, about the same as Everest.

Yeah I say they are all in spec.....PSU should be enough.

the only way to get true PSU volts is with a digital multi meter software is inaccurate. if using software the BIOS is most accurate.

as sneeky pointed out PSU's have an allowable tolerance generally 5%-10% (either + or -) you seem to be in that range and above the MIN required so you should have no worries

Alrighty, thanks. Didn't know the tolerance could be that much, (+-5%)
