Get a 20/24 Pin connector that usually attaches to your computer’s motherboard. It is usually the main connector for the power supply.

Find the green pin and the black pin (15 and 16 pins). You will be placing the paperclip ends on the green pin and the neighboring black pin. Before doing so, double-check to ensure that it disconnects the power supply.

  • The green pin is usually the 15th on the pin chart.

Enter a paperclip

  • Once you have inserted the paperclip on each pin, place the cable somewhere not to be disturbed.
  • Connect the power supply again to the store, then install the back switch.
