The power input terminal and the first signal terminal are connected to a power supply. The power output terminal and the second signal terminal are connected to a computer motherboard. If the first and second terminals are disconnected from each other when the computer motherboard works, the power supply stops working. The testing circuit includes a fixed resistor and a control chip parallel connected between the power input and output terminal. The control chip stores a predetermined voltage threshold, and detects voltage between the two terminals of the fixed resistor, and compares the measured voltage with the predetermined voltage threshold.
