Abstract

An automatic power supply testing system records a preset test order of first and second power supplies with a recording module. The automatic power supply testing system controls a first control unit to connect a first connector connected to the first power supply to a simulation load to test the first power supply according to the preset test order by a determination control module and obtains a first test result. The automatic power supply testing system controls a second control unit to connect a second connector connected to the second power supply to the simulation load to test the second power supply after determining that the first test result is displayed and obtain a second test result. A display module displays the electrical stability of the first and second power supplies.
