A power supply device for a server device includes a power supply circuit, a control microchip, and a compensation element. The compensation element is a resistor having a negative temperature coefficient. The control microchip controls the power supply circuit to generate an output voltage to power the server device in response to receiving a voltage of an external power supply. When the power supply device generates excessive heat in use, a resistance of the compensation element decreases to maintain a total resistance of the power supply device at substantially an original value.
