Abstract
A power supply device includes a transformer and a heat-dissipating mechanism. The heat-dissipating mechanism includes a heat-dissipating fan unit and an activating unit. The heat-dissipating fan unit is connected pivotally to the transformer, and is pivotable relative to the transformer to lie on a top surface of the transformer. An inclination angle of the heat-dissipating fan unit relative to the top surface of the transformer is adjustable. The activating unit includes a control switch for controlling activation of the heat-dissipating fan unit.
