ABSTRACT:
A voltage test circuit for testing a computer power supply includes a voltage input unit configured for receiving voltages from the computer power supply, a voltage output unit configured for outputting the voltages to a plurality of electrical loads, a test unit, a switch control unit, and a capacitive load module. The test unit is connected between the voltage input unit and the voltage output unit for testing output ripple and noise of the voltages. The capacitive load module includes a plurality of capacitive loads. The switch control unit is connected between the voltage input unit and the capacitive module for selecting a suitable capacitive load according to the computer power supply.
