Abstract

The invention relates to a power testing device which comprises a first adapter, a first testing board, a second adapter and a second testing board, wherein the first testing board is connected with the first adapter, and the second testing board is connected with the second adapter. In the power testing device, signal terminals in a power supply unit are respectively connected to the first testing board and the second testing board through the first adapter and the second adapter, and the voltage of all terminals of the power supply unit can be tested through testing the pin voltage of both the first testing board and the second testing board.

Description

technical field [0001] The invention relates to a power testing device. Background technique [0002] Existing computers are powered by a Power Supply Unit (PSU). The power supply unit outputs power to the main board, optical drive, hard disk, etc. of the computer. Testing the output of the power supply unit is usually achieved by testing the corresponding power signal pins on the motherboard of the computer with a probe. However, due to the dense distribution of signal pins on the motherboard, it is easy to touch other signal pins when using a probe to test the power signal pins on the motherboard, causing a short circuit, causing interference to the test or even burning the motherboard. Contents of the invention [0003] In view of the above, it is necessary to provide a power testing device that does not need to test the signal pins on the main board and is not prone to short circuit. [0004] A power testing device for testing the voltage of a power supply unit, the...
