Stop scaring the person...
When you connect the multimeter to ground and a live wire, is that is series or parallel :?:
That is outright wrong advice in this case.You need to get yourself a multilmeter and measure the current (measured in amps) on the wires to ensure they are within the sticker specs.
hey man
i came across this power supply tester which i think it's better than the one suggested previously
Link: Tester produced by Frozen CPU
Features:
Tests 20-pin and 24-pin power supplies
Tests SATA power
Tests Pentium 4 power connector
Tests PCI-Express power connectors
Tests Xeon power connectors
Tests Floppy drive connectors
Tests standard 4-pin power supply connectors
Tests for +3.3V, -12V, PG, +5VSB, +12V, -5V, +5V outputs
cheers!!!
You need to get yourself a multilmeter and measure the current (measured in amps) on the wires to ensure they are within the sticker specs. Black wires on the power supply are ground. Red are +5V DC and yellow are +12V DC. As for the other colors.. you'll need to look that up or go by the diagram on the link below.
Make sure the multimeter is set to measure current (I) and set to DC power (direct current). The black lead connects to ground and the red lead connects to a voltage rail (red or yellow wire)
The very same green wire is whats shorted on the motherboard by your START or your ON button.
All the switch does is short the green to ground.
You can leave off the switch connector & short the 2 pins on the mother board to power up the pc as well which is how many people power up boards outside a pc case.
Can someone give me some info on how to test a Power Supply to see if it is good before I try to install it. Thanks
You could use what a real psu company does:

That testing unit runs all the tests and while the psu is in a 50C state rather than the 22-25C all other psu makers use to inflate the real "clean" output of thier products.
a power supply normally is good no matter what the watts are.
But if you want a really good one (dont know why you are wanting to test the PSU, the really only way to test it is to test it under a load). What i would recoomend is looking at what the specs are for the power supply and there are power supplies that have dual rails. Those are the better ones, they distrubute voltage and power to devices better becuase instead of using one rail for all your devices, you have two. Testing it for current and the volts is a good idea, only when you suspect your PSU unit is going bad. Otherwise, why fool with that?...
