Description
Technical Field
The field relates to the field of computers, and more particularly to a system and server for extending server power down.
Background
The conventional server power supply has two standards of ATX and SSI, but with the more standardization of the SSI standard, the SSI standard can be more suitable for the development of the server, and the later server power supply also must adopt the SSI standard. The SSI specification is beneficial to promoting the development of servers, CPU (central processing unit) dominant frequencies which can be supported in the future are higher and higher, power consumption is higher and higher, the capacity, the rotating speed and the like of a hard disk are higher and higher, and more high-speed devices can be hung outside. In order to reduce heat generation and save energy, in the future, SSI server power supplies will be developed towards low voltage, high power, high density, high efficiency, distributed type, and the like. The server adopts a great number of accessories, the number of supported CPUs can reach 4 or more, the number of mounted hard disks can reach 4-10 blocks, the memory capacity can also be expanded to 10GB, the accessories are large households consuming energy, for example, the power consumption of the accessories is already 80 watt (W) when a Xeon (to strong) processor is adopted by a middle-high-end industrial standard server, and the power consumed by each SCSI hard disk is more than 10 watt (W), so the power required by the server system is far higher than that of a PC (personal computer), the power required by the PC is enough as long as 200 watt power supply, and the server needs a high-power supply of more than 300 watt and up to kilowatt.
A server power supply module (PSU) is an important component of a server, and mainly provides a stable and reliable voltage and current input for the server.
