How to test your computer's power supply

There are certain simple steps you need to adhere to test the power supply of your computer like turning off the power switch and removing the plug from the power supply. Then you need to remove the cable and dismantle the power-supply section. This is done to completely remove the power supply. Then, you locate the ATX connector, the black and green wires, and bond them together. Subsequently, you need to provide the power supply and switch on the system again and after ensuring the system ventilation is functioning well, you check if the connection is correct. The 12 volts of power supply should be displayed on the Molex.

To be able to test your computer's power supply, you can follow the instructions below:

1. Turn off your power switch and remove the plug 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 the main ATX connector and find the green wire.
4. Also locate 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. Switch back 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.

A computer's power supply can be calculated by using a power supply calculator. It is not considered as an easy task as it requires you to give importance to every single part of your computer from CPU to Graphics Card, from Primary Optical Drive to Third Optical Drive and from liquid cooling to Wireless card. One should enlist the details about all these and then using a calculator, you may find out the power supply.
