Abstract

Motherboard voltage testing device includes a power supply module for supplying a DC voltage, an illuminating module, and a switching module for detecting a DC voltage of a motherboard. A first terminal of the switching module is coupled to the power supply module, and a second opposite terminal of the switching module is coupled to the illuminating module. When the switching module detects the DC voltage of the motherboard is in the motherboard, the illuminating module is configured to receive the DC voltage of the power supply module to emit light, and when the switching module detects there is no remaining DC voltage on the motherboard, the illuminating module cannot receive the DC voltage from the motherboard and the illuminating module is power off and does not emit light.
