my shuttle psu i bought last month has been serving my shuttle well.. the 300 watt one... its powering a p4 3.2 northwood, evga 7800gs superclocked 1 IDE hd, 1 DVD R/RW and a floppy and a keyboard mouse and what not... ive notived today that the +12 rail however in PCwizard shows 11.19 or 11.25... is that a problem, is my psu dying?
 
Is your system acting flakey?

Is that voltage the +12 or the -12?

Measured with a meter or software?

If the answere to 1 is NO, and you ARE reading the +12, but not with a METER, then measure it with a meter and get back to us. I'd definitely get it replaced if that reading IS of the +12 rail with a METER - that is well under the +/- 5% spec.

system seems fine, reading +12 but not with a meeter, i need help on measuring it with a meeter.. how would i go about doing it and stuff... and thats about it
 
Any yellow wire coming from the PSU is a +12 lead - any black wire is ground. Set meter to read voltage (10V scale should be fine - some may need to be set at 100V scale - whichever is nearest or higher than 12V) black lead from meter goes to ground, red goes to +12 source. simple.

Voltages on boards are considered to be within tolerance if within 5% of the wanted voltage. So, anything below 11.4 volts is out of spec.

I doubt your power supply is dying so much as it is overtaxed.
 
ya, what they all said. software voltage readers suck. In my experience they are totally unreliable. Unless things start acting up then there is no need to worry a bit.
