power supply

[Brian G]

How could I test a power supply?
With out any kind of tester?
And if thats the only way, What kind of tester would be recomended? (without spending a millio$)
I got a pc that does nothing, Imean zip. Guessing its the Power Supply.
But since this is not the first one, I should learn more.
Thanks for any help

You can buy a cheap multimeter at ant hardware store, but if are going to stay in computers buy a good one.

WarningThis test is for those who have extensive electronics training. Do not try this if you do not have extensive electronics training. Make sure there is enough load connected to the power supply before testing ( at least motherboard and one hard drive)!

ATX power connector is layout like above. 5VSB constantly provides 5V power to the connector through pin 9. If you have a voltmeter, while the power supply fan does not turn on, you could identify which pin is pin 9. Normally there is a clip on the connector between pin 15 and 16. If you can identify pin 14, which is power-on pin, you can using a piece of wire short the pin 14 and 15. If you power supply has power connected to it and power switch on the power supply is on, you will see the fan is turnning by now. Otherwise, your power supply may have problem.

or get one of these
