Abstract
A power source device coupled to a power device includes an output port and a controller. When the output port is coupled to a connection cable, the controller is activated to generate a handshake signal, so as to communicate with the power device. When it is determined that the power device is able to be powered according to the handshake signal, the controller controls the power supply device to power the power device through the connection cable. When the connection cable is not coupled to the output port, the controller is deactivated and thus the handshake signal is not generated.
