Abstract
A power system is disclosure. The power system includes a processor, a power supply device, and a power-managing module. The power supply device includes a converter and a controller, the converter has a main power output for outputting a main voltage and a standby power output for outputting a standby voltage, and the controller is electrically connected to the converter. The power-managing module is communicating with the electronic device and the power supply device and includes a switch and a power manager, the switch is electrically connected to the main power output and the electronic device, and the power manager is electrically connected to the electronic device, the switch, and the controller. When the electronic device is in a standby operation mode, the power manager makes the switch turn off to prevent to main voltage from conducting to the electronic device.
