PROBLEM TO BE SOLVED: To provide a multi-output power supply capable of simply performing stable voltage value control. SOLUTION: The multi-output power supply, having a transformer 4 with a plurality of secondary coils 41a, 41b, 41c and outputting the power guided to the secondary coils 41a, 41b, 41c to a plurality of load circuits 19, 20, 21 respectively, is provided with an acquisition means for acquiring power consumption information displaying the magnitude of the power consumed by the first to third load circuits 19, 20, 21 respectively connected to the secondary coils 41a, 41b, 41c; a selecting means for selecting one of the secondary coils 41a, 41b, 41c, based on the power consumption information acquired by the acquisition means; a first to a third voltage detecting circuits 13, 14, 15 for detecting the voltage values of the secondary coils 41a, 41b, 41c selected by the selecting means; and a feedback controlling means for performing feedback controlling of the voltage values of the secondary coils 41a, 41b, 41c, based on the voltage values detected by the first to the third voltage detecting circuits 13, 14, 15.
