If the power supply needs to be used off the ground, the four groups of legs 19 can be flipped out of the grooves 18, so that it can be vertically rotated 90° and supported on a plane to ensure the heat dissipation of the heat dissipation groove 17, thereby reducing the impact of the power supply being directly placed on the plane. The fixing seat 7 can also provide a suspended installation of the power supply. Two groups of heat dissipation components are arranged inside the power supply base box 1. The internal hot air is drawn by the negative pressure fan 15 to flow toward the through groove 16 for dissipation, thereby leading the hot air to the outside through the multiple groups of guide fins 11 installed at the power supply casing 8, thereby improving the heat exchange efficiency.
