Atest circuit includes a test unit and a converting unit. The test unit includes a first connector connected to a power supply unit, a second connector connected to a motherboard, a sensing resistor, a controller, and an electronic switch. Two input pins of the controller are connected to two ends of the sensing resistor. A first terminal of the electronic switch is connected to the first connector through the sensing resistor. A second terminal of the electronic switch is connected to a control pin of the controller. A third terminal of the electronic switch is connected to the second connector. The converting unit includes a third connector connected to a monitoring device and a converter. Two input pins of the converter are connected to two output pins of the controller. Two data pins of the converter are connected to the third connector. |
