Abstract
An exemplary electronic device includes a mother board, a power source, and a power extending board detachably connected between the power source and the motherboard. The power source includes a golden finger interface. The power extending board includes a receiving socket, a first conversion circuit, and a first connector. The golden finger interface is plugged into the receiving socket. The first conversion circuit is connected to the receiving socket, converts first and second voltages from the power source into third and fourth voltages, and outputs the first, third, and fourth voltages to the motherboard.
