A device for centrally installing pcie cards

Abstract

A device for centrally installing PCIE cards, comprising a backplane, a PCIE card slot and a PCIE connector arranged on the backplane, an independent power supply connected to the backplane and a PCIE adapter card, the PCIE card slot is connected to the PCIE card slot through the PCIE bus The PCIE connector is connected, and the PCIE connector is connected to the PCIE adapter card through the PCIE cable. This device realizes the separate power supply of the computer system and the PCIE card, and can arbitrarily support the PCIE card with high power consumption, and is no longer limited by the computer. The limitation of the system power supply, and the design of multiple power supplies can be used, which solves the problem of power supply.

Description

[0001] Technical field: [0002] The invention relates to a device for installing a PCIE card. [0003] Background technique: [0004] PCIE bus technology has now been widely used in computer systems. Recently, Intel has introduced the latest generation of Xeon CPUs. One of its very important features is the integration of PCIE bus into the CPU, instead of bridges as before. The group leads PCIE bus, which shows the importance of PCIE bus technology and the long-term life cycle of PCIE bus. At present, the most common method of using PCIE bus is to insert PCIE cards into the PCIE slots of PCs, servers and other computer systems, or use LOM (Locate On Motherboard) to place the relevant circuits on the PCIE cards on the motherboard. This method has the following shortcomings: 1. The power consumption is large and the power design is difficult; the PCIE card and the PC, server and other computer systems where it is located share a power supply, which increases the burden of power suppl...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: 1. The power consumption is large, and the power supply design is difficult; the PCIE card and its PC, server and other computer systems share a power supply, which increases the burden of power supply design

And for such a system, only one power supply is often allowed to be plugged in, so designing a power supply that can support 700W power consumption is still very challenging, and the price is relatively expensive

If more than 2 GPU accelerator cards are supported, the design of the power supply will be more difficult

2. The problem of heat dissipation is difficult to solve; in a computer system, CPU, memory and chipsets are the main heat generating devices. If a high-power PCIE card is inserted, the PCIE card is also a main heat source

For most of the current systems, the PCIE card is located at the air outlet of the entire system, the surrounding temperature is relatively high, and the heat dissipation environment is harsh, which increases the difficulty of heat dissipation design.

3. The size of the PCIE card is limited; PCIE card standards are divided into half-height half-length, full-height half-length, full-height Most computer systems are limited by cost and industry standards, so it is difficult to reserve such a wide space for PCIE cards

In this way, there is a problem that the high performance and space of the PCIE card are mutually restricted.

4. The number of PCIE cards is limited; in order to pursue higher performance of the computer system, people hope to insert more and more PCIE cards. It is possible to insert 1 PCIE card, and in a few cases, 2 PCIE cards can be inserted, and it is rare to insert more PCIE cards
