Zusammenfassung:	A power supply device and a power supply method are provided. The power supply device is configured to generate a first feedback signal according to an output power source, and operate in a skip mode (or called burst mode) according to the first feedback signal. The power supply device is configured to obtain an overall efficiency according to an input power and an output power, and obtain a difference between the overall efficiency and a preset efficiency. When an output current value of the output power source is within a predetermined range and the difference is greater than a first value, the power supply device generates a second feedback signal and stops operating in the skip mode according to the second feedback signal.
