How do You Check if the PSU is Working Properly?
If you have applied the resetting methods mentioned above but your PC is still not switching on, you can test if the PSU is functioning properly by following the paper clip test. We recommend performing this test by removing the power supply unit from the PC to avoid any hardware damage.
- Take a simple paperclip and turn it into a U-shaped two-faced pin. You can also use an insulated wire.
- Locate the 24-pin connector from the power supply into the motherboard and make sure the PSU is off.
- Take the 24-pin connector and locate the ground and PSU ON connections. Usually, the PSU ON will be attached with a green wire, while any black wires will be on the ground. You can check the chart mentioned below for further reference.
- Take one end of the U-shaped pin and put it in the ground port of the 24-pin connector.
- Put the other end of the U-shaped pin in the PSU ON port of the 24-pin connector.
- Turn ON the power supply to check for the power light on the power supply and see if the PSU fan works properly.
The working of fans or flashing lights will indicate that the power supply is working fine and the fan is running; it means there is nothing wrong with it, and you should proceed to check the rest of the PC components after the power outage.
