A power supply device includes a mini projecting module, a power converting module and a signal transmission element. The power converting module includes a power input part, a power converting circuit and a power output part. The power converting circuit is used for converting the input voltage into a first output voltage and a second output voltage. The first output voltage and the second output voltage are respectively transmitted to an electronic device and the mini projecting module. The first output voltage is transmitted to the electronic device through the power output part. The signal transmission element is used for connecting the electronic device or an image signal source with the mini projecting module so that an image signal provided by the electronic device or the image signal source is transmitted to the mini projecting module through the signal transmission element.
