A power supply test system for testing reliability of a power supply includes a test chamber, a temperature detecting unit, a control unit, a heating module, and a refrigerating module. The test chamber accommodates the power supply. The temperature detecting unit detects temperature signals in the test chamber. The control unit presets a predetermined temperature value and receives the temperature signals. The heating module receives a first control signal from the control unit when a value of the temperature signal is less than the predetermined temperature value. The heating module heats the test chamber. The refrigerating module receives a second control signal from the control unit when a value of the temperature signal is greater than the predetermined temperature value. The refrigerating module refrigerates the test chamber until the value of the temperature signal is equal to the predetermined temperature value.
