1. A motherboard, comprising:
a connector, configured to be electrically connected to an expansion card, and comprising a first pin, a second pin, and a third pin;
a controller, comprising:
an analog-to-digital converter, coupled to the first pin, wherein the controller identifies a digital voltage value of the first pin by the analog-to-digital converter, and generates a power supply requirement and a signal transmission requirement corresponding to the expansion card based on the digital voltage value;
a platform controller hub, having a plurality of platform signal pins; and
a switch block, receiving a plurality of power supply voltages, and coupled to the second pin, the third pin, the controller, and the platform controller hub, wherein the switch block provides one of the power supply voltages to the expansion card through the second pin based on the power supply requirement, and the switch block controls the third pin to be coupled to one of the platform signal pins based on the signal transmission requirement.
