PSU-based power supply system

Abstract

The embodiment of the invention discloses a PSU-based power supply system, and a first output port of the PSU is connected with a main control component of a mainboard through a voltage converter, andis used for supplying power to the main control component in a standby state of the system. A second output port of the PSU can be connected with a load variable component of the mainboard, or the first output port and the second output port of the PSU can be connected with the load variable component through a power supply switching device, and the enabling end of the PSU is grounded, so that the first output port and the second output port are ensured to have voltage output when the PSU is inserted into the mainboard; the current value output by the second output port is relatively large, so that the power supply requirement of the load variable component is met. The second output port of the PSU is connected with each startup operation component of the mainboard through a switch component, and the switch component is in an off state when the system is in a standby state; after the system is started, the switch component is in a conducting state, and it is guaranteed that all starting operation components do not additionally consume electric energy when the system is in a standby state.

Description

technical field [0001] The present invention relates to the technical field of server power supply, in particular to a PSU-based power supply system. Background technique [0002] With the development of cloud computing applications, the usual server structures are mainly deployed in 2U chassis on racks in computer rooms. Among them, U is a unit representing the external size of the server, which is an abbreviation of unit. In order to enhance the functional scalability of the server in 2U space, a high-speed serial computer expansion bus (Peripheral Component InterconnectExpress, PCIE) adapter card is often used to transfer multiple external daughter cards with different functions and performances through the motherboard PCIE, such as: Gigabit network card, 10 Gigabit network card, SAS card, RAID card, etc. By matching different external sub-cards, the 2U general-purpose server can meet the application requirements of different users. [0003] A general 2U general-purpos...

AI Technical Summary

Problems solved by technology

When the number of external sub-cards matched with the server system increases to a certain number or the power consumption of the external sub-cards is high, the current required for power supply will exceed 3A, resulting in insufficient standby power supply of the PSU.

[0005] It can be seen that how to solve the problem of insufficient standby power supply of the PSU is a problem to be solved by those skilled in the art
