[0002] With the development of electronic technology, graphics cards, as an important component of computers, are also constantly improving in performance and design. In the design of graphics cards, in order to improve performance and stability, it is often necessary to add additional power supply circuits. However, traditional graphics card designs usually place all power supply lines directly on the main PCB (printed circuit board), which not only increases the complexity of the PCB, but may also cause signal interference and unstable power supply.

[0003] To solve this problem, some new graphics card designs use a method of separating the main PCB from the power supply PCB. In this design, the power supply PCB is plugged into the motherboard through a specific interface to provide power to the main PCB. This design not only reduces the wiring on the main PCB, but also improves the installation flexibility and stability of the graphics card.

[0004] However, the existing connection method between the power supply PCB and the motherboard has certain limitations. Usually, this connection method uses bolts for fixed installation. During the assembly process, if errors occur, such as inaccurate bolt positions or inaccurate alignment between the power supply PCB and the motherboard, it may make it difficult to insert the power supply PCB into the PCIe card slot of the motherboard, thereby affecting the installation and use of the graphics card.
