How to Test Power Supply
From en.kioskea.net site I found step by step to test power supply manually. But remember you should be an advance user to test these steps and do it with your own risk.

You can follow the instructions below, To be able to test your computer's power supply:
1. Turn off your power switch and plug it out from the power supply.
2. Remove the cable from the CPU and start unscrewing the power supply section in order to remove the whole power supply (square metal box) from the CPU.
3. Once done, locate for the main ATX connector and find the green wire.
4. Also locate for the black wire near the green wire and with the use of a paper clip, connect and safely bond the two together with a piece of isolating tape.
5. Put back all the power supply and switch the system on again and ensure that your system ventilation is working.
6. To check whether the connection is correct, the Molex in between the yellow and black wire should display at least 12 volts.
