a server

Abstract

The invention discloses a server, comprising: a plurality of power supplies, each of which is connected to a power adapter board; a GPU board, the GPU board includes a first power supply copper bar and a plurality of GPU board adapter boards, wherein each The GPU board adapter boards are all connected to one of the power adapter boards, so that the power supply supplies power to the GPU board through the power adapter board and the GPU board adapter board; The first power supply copper bar is connected so that the GPU board supplies power to the motherboard through the first power supply copper bar and the second power supply copper bar. The solution proposed by the present invention changes the system power supply current path from the PSU directly into the GPU board to supply power to the GPU, and then through the GPU board->power supply copper bar->main board to supply power. In this way, the PSU is used to directly supply power to the GPU board, and then the power is supplied to the main board through the power supply copper bar, which will greatly reduce the energy transmitted by the power supply copper bar. Even if the GPU power increases, the power consumption of the copper bar will not increase. Therefore, There is no need to increase the size and number of copper bars.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a server. Background technique [0002] In the existing situation, because the power supply goes directly to the motherboard through the PSU, and then enters the GPU board through the power supply copper bar. When the GPU type is being upgraded, the power consumption of the GPU will increase compared to the previous generation, and the current architecture can only support up to 8 300W GPUs. [0003] After the GPU upgrade, its power consumption will increase to 450W. If the current power supply architecture continues to be used, the power supply copper bars need to be further enlarged and occupy a larger area. At the same time, the current density is also very large, and there is a risk of burning the board. Or increase the interconnected 4 power supply copper bars to 6, but this will occupy more space for the motherboard and GPU board, and the motherboard space will be more tight,...

AI Technical Summary

Problems solved by technology

If you continue to use the current power supply structure, the power supply copper bar needs to be further enlarged to occupy a larger area

At the same time, the current density is also very high, there will be a risk of burning the board

Or increase the number of interconnected 4 power supply copper bars to 6, but this will occupy more space on the motherboard and GPU board, and the space on the motherboard will be more tight. The motherboard may not be able to complete the design under the current chassis size.

At the same time, as the number of power supply columns increases, the structural requirements will be higher. Smaller errors are required to ensure that there is no problem with the connection of the power supply copper bars. This problem will lead to a decrease in production yield.
