1. An expansion apparatus, comprising:
a power supply device comprising a controller and an output terminal and providing a predetermined power through the output terminal;
an expansion module comprising an input port and a plurality of output ports, the input port coupled to the output terminal, and the output ports operable to be coupled to a plurality of electronic apparatuses; and
a control module having a full-power output mode and a disabled mode and receiving a device identifier provided by the controller through the input port to learn the predetermined power, so as to selectively adjust the output ports to operate in the full-power output mode or the disabled mode based on the predetermined power, thereby limiting a total power consumed by the electronic apparatuses and the expansion module to be less than or equal to the predetermined power.
