The multi-channel power supply comprises a first channel, a second channel, a current sensing module, a current average control circuit, and a modulator. The first channel and the second channel respectively transform an input voltage into an output voltage according to a first pulse width modulation (PWM) signal and a second PWM signal. The current sensing module respectively sense a first channel current and a second channel current to output a first sensing current and a second sensing current. The current average control circuit generates a first error current and a second error current according to the first sensing current and the second sensing current and an average current thereof. The modulator generates the first PWM signal and the second PWM signal according to the first error current, the second error current and the output voltage.
