ABSTRACT:
A system for testing power supply performance is provided. The system includes a power supply having a plurality of outputs for outputting voltages, a plurality of display units corresponding to the plurality of outputs, for reflecting performance of the power supply, a plurality of resistance-matching selectors corresponding to the plurality of outputs, for supplying selective resistance, a voltage adjustable direct current source, and a selective switch. The display units are connected between first terminals of the outputs and the resistance-matching selectors, respectively. The resistance-matching selectors are in turn connected to ground. The voltage adjustable direct current source has a pole selectively connected to a second terminal of one of the outputs via the selective switch, and another pole grounded.
