The pin 9 of the ATX power supply is connected to one end of the power-on key through a current limiting resistor Ra. One end of the current-limiting resistor Rb is connected with the trigger circuit, and the other end of the current-limiting resistor Rb is connected with the b pole of the triode. The c pole of the triode is connected to the 14 pin of the ATX power supply, and the e pole of the triode is grounded. The other end of the power-on key and the trigger circuit are also grounded.
