How 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.
