The utility model provides a main board USB interface testing device, comprising at least one testing unit which comprises a first connecting point and a second connecting point which are used for respectively connecting with two power connecting points of the main board USB interface in series and a resistance load connected with the first connecting point and the second connecting point in series, and the load can adopt the resistance of more than or equal to 10 ohm. The USB interface testing device is mainly used for testing the power supplying capacity of each USB interface of the main board and measuring the voltage of two power connecting points disconnected with the USB interface testing device on the both ends of the main board USB interface and the voltage of the two power connecting points falling on the resistance load after connecting with the USB interface testing device on the both ends of the USB interface and counts and obtains the voltage consumption of the USB interface so as to judge the power supplying capacity of the USB interface, and the USB interface testing device makes use of the Standby voltage of the main board to test so that the USB interface testing device doesn't need to electrify the main board when tesing. The main board USB interface testing device has simple structure, convenient use and good testing effect.
