Problems solved by technology
However, once multiple graphics cards are installed in the computer system, the current design is to supply power to all the graphics cards. Since there is no proper switching mechanism to turn off the power supply of the graphics cards, it will cause waste of power and is not environmentally friendly.

The invention provides a host device and a computer system which can save electricity for graphics cards. The host device is equipped with at least two graphics cards and comprises a first connecting interface, a second connecting interface, a power source and a switch element, wherein the first connecting interface is electrically connected with one of the graphics cards, the second connecting interface is electrically connected with the other graphics card, the power source provides electricity to the graphics cards through the first and second connecting interfaces, the switch element is coupled between the power source and the second connecting interface, besides, the switch element is used to switch between an enable mode and a disable mode, switches on the power source to provide electricity to the graphics card connected with the second connecting interface in the enable mode, and switches off the power source to avoid providing electricity to the graphics card of the second connecting interface in the disable mode. The host device and the computer system are provided with the switch element capable of switching off the power source of the graphics cards to avoid electricity waste, thereby having functions of saving energy.
Description
technical field [0001] The invention relates to a host device and a computer system, in particular to a host device and a computer system which are equipped with multiple graphic cards and can save power consumption of the graphic cards. Background technique [0002] Currently, computer systems support multi-GPU (multi-GPU) processing technology. For example, the nVIDIA company in the United States has proposed a dual-graphics card that can be installed in two groups of PCIe slots. When the computer system enters the dual-card processing mode, the single The screen is divided into two parts horizontally, and the dual cards are used for calculations, thereby improving the overall computing efficiency, but the relative dual card processing mode consumes more power than a single graphics card. [0003] Under normal circumstances, the dual-card processing mode is mostly used to make the graphics of game software, such as 3D geometric operations faster, so that the game has bette...
