Abstract: A power supply which supplies power to a circuit board includes a support unit, an electricity output unit and a voltage converting module. The circuit board, the electricity output unit and the voltage converting module are electrically connected to the support unit. The voltage converting module can convert an output voltage of the electricity output unit to a working voltage of the circuit board. The power supply has a low manufacturing cost and can support an electricity output unit with different voltage.
