Put a resistive load (resistor, fan, HDD, etc.) on the supply, turn the thing on, and measure the voltages. You might want to put a load on every rail, as some PSUs appear to require this.
Depends on the meter, really. Something like a good Fluke (i own a Fluke 179) is very accurate and you can trust the numbers you see on them, while a cheap Mastercraft meter might have 5% or more error on its measurements.oqvist said:how much do a multimeter cost and how do I use it to test it?

For a good PSU load, get an old computer you don't care about or throw one together with spare parts. Fans and HD's alone won't put a good enough load on a PSU to "properly" test one.
To use the meter, ground the black wire on the meter to the case, or to a black wire on a molex. Then probe (with the red probe) through the back of the molex connector where it meets your motherboard, and measure there.
