Embodiment Construction

[0013] see figure 1 A preferred embodiment of the present invention provides a memory power supply system 100 for supplying power to a plurality of memory 201 disposed on a motherboard 200 of electronic devices such as computers and servers (not shown in the figure). The plurality of memories 201 may be dual in-line memory modules (DIMMs). The memory power supply system 100 includes a power supply 11 and a number of power adapter boards 12 corresponding to the number of the memory 201 . The power adapter boards 12 are connected to the power supply 11 . Each memory 201 is respectively connected to the power supply 11 through a corresponding power adapter board 12 .

[0014] The power supply 11 is an external power supply for providing a first DC voltage to the power adapter boards 12 respectively. The power supply 11 includes a plurality of connection parts 111 , and the connection parts 111 are all universal serial bus (universal serial bus, USB) interfaces. In this embodi...

Abstract

The invention provides a power supply changeover panel which comprises matching portions, a buck regulator and memory inserting grooves, wherein the matching portions are used for being connected with a power supply which is used for providing a first direct voltage, the buck regulator is connected with the matching portions and used for converting the first direct voltage to a second direct voltage, and the memory inserting grooves which are connected with the buck regulator is used for enabling memories to being inserted and transmits the second direct voltage output by the buck regulator to the memories. Due to the fact that the power supply changeover panel is respectively corresponding to the memories, the buck regulator operates under the condition of full load, and thereby electric energy conversion efficiency of every buck regulator is improved, and consumption of energy is reduced. The invention further provides a memory power supply system with the power supply changeover panel.

Description

technical field [0001] The invention relates to a power adapter board and a memory power supply system with the power adapter board. Background technique [0002] The motherboard of electronic devices such as computers and servers usually includes a voltage regulator down (VRD) for converting voltage. After the external power supply is stepped down by the VRD, it supplies power to the memory respectively. When designing the motherboard of an electronic device, the output power of the VRD is generally designed to be equal to or slightly greater than the sum of the working power when the number of memories is the largest, so as to meet the power supply demand. Generally, if the load of VRD is smaller (that is, the number of loaded memory is less than or even much smaller than the maximum number set during design), the power conversion efficiency is lower; and when the load is larger (that is, the number of loaded memory is close to or equal to the design When setting the max...
