1. A power supply device, comprising:
a conductive housing;
a circuit board, disposed inside the conductive housing;
a rectifying module, disposed on the circuit board and having a primary side for input power and a secondary side for a load;
a first surge protection module, wherein one terminal of the first surge protection module is electrically connected to the primary side;
a second surge protection module, wherein one terminal of the second surge protection module is electrically connected to the secondary side; and
a grounding module, comprising:
a first grounding element, electrically connected to the other terminal of the first surge protection module electrically connected to the primary side of the rectifying module;
a second grounding element, electrically connected to the other terminal of the second surge protection module electrically connected to the secondary side of the rectifying module, wherein the second grounding element and the first grounding element are not directly connected; and
a fastening element, passing through the conductive housing, the circuit board, the first grounding element, and the second grounding element so that the conductive housing, the first grounding element, and the second grounding element are electrically connected to one another.
