Problems solved by technology
[0002] In the current information age, there are generally multiple DC (Direct Current, DC) power supplies inside servers, computers, or industrial equipment, which are used to convert the DC voltage output by the Power Supply Unit (PSU) into a DC voltage of the target size , internal DC power supply and high-value components may appear during debugging, handling and long-term use, such as central processing unit (Central Processing Unit, CPU), integrated south bridge (Platform Controller Hub, PCH), dual in-line memory module ( Damage to Dual Inline Memory Modules (DIMM), power chip (Integrated Circuit, IC), etc., resulting in a short circuit of the output of the DC power supply
[0003] At present, there is no automatic detection scheme for the short-circuit detection of the output impedance of the DC power supply unit. If the power is turned on without detection, once the output of the DC power supply unit is short-circuited, it is very likely to burn out the main board and high-value components, resulting in unnecessary Necessary loss

The invention provides a power supply short circuit detection device and equipment. The device includes: a power supply unit PSU, a DC power supply unit, a short-circuit detection module and an information prompt module. The PSU is connected to the DC power supply unit. The standby power supply port of the PSU and the DC power supply unit are connected to the short-circuit detection module respectively. The output impedance of the unit, the output prompt signal, the short-circuit detection module is connected with the information prompt module, and the information prompt module prompts whether the output of the DC power supply unit is short-circuited according to the prompt signal, realizing automatic detection of whether there is a short circuit in the DC power supply unit, and improving Improve the detection efficiency and increase the stability of the circuit to avoid damage to other devices caused by blindly starting up in the case of a short circuit in the DC power supply unit.
