Power supply troubleshooting?

Not an expert on power supply troubleshooting, so I'm seeking advice.


How you use the p/s readings and such to tell if you don't have a sufficient power supply and/or a bad one? I know they should be close, but how close and which readings are important? Should it be checked during cpu/hdd activity?


Any links are appreciated cause I couldn't find any good resource. Willing to learn the basics.

And before you say it....I know the basic rule of thumbs is a quality (antec) 400-600 (or even higher) wattage is good, but then again, I don't o/c and have crazy devices connected.


thx
 
The definitive baseline answer, from the official ATX spec: link Tighter tolerances won't hurt, of course. Use a multimeter to test, not software or BIOS readings, if you want to be certain of accurate readings.

is 11.673V reading ok for +12V?

Take a look at the chart linked to by mechBgon. The answer is yes, as 11.673 is within the specified 5% margin of tolerance.
