A power supply module test jig, which belongs to the field of power supply testing. The power supply module test jig comprises a power supply input module, an ammeter, a switch K1, an oscilloscope, a plurality of voltmeters, and loads connected to the voltmeters in series. Switches K2 are provided between the voltmeters and the loads. The power supply input module is connected to an input end of a power supply module to be tested via the ammeter; the switch K1 is arranged between the ammeter and the power supply module to be tested; the oscilloscope is connected in parallel between two ends of the power supply module to be tested; and the plurality of voltmeters are connected in parallel to an output end of the power supply module to be tested. The beneficial effects of the power supply module test jig are: a high test efficiency, being capable of optionally switching when at a zero load and a 4/5 full load, and testing a self-adaptive adjustment rate of a power supply module to be tested when same is at a zero load and 4/5 full load according to the monitoring display of an output voltage of a voltmeter, thereby improving the stability thereof in an actual working circuit.
