Abstract

A control circuit for a power supply includes a first switch, a second switch, a third switch, and an output terminal. The first switch is connected to a super input/output (SIO) chip to receive a control signal. The third switch is connected to the first switch via the second switch, and is connected to a power supply and the output terminal. When the control signal is at a high level, the first switch is turned on, the second switch and the third switch are turned off, and the output terminal does not output the power supply. When the control signal is at a low level, the first switch is turned off, the second switch and the third switch are turned on, and the output terminal outputs the power supply.
