[0096] Optionally, in the embodiments of the present application, the motherboard connector on the server motherboard may or may not be too far or too close to the server power connector. If the distance between the motherboard connector and the server power connector is too far, a relatively large current flow, i.e., the in-board current, will be generated between the motherboard connector and the server power connector, and there will be too many copper foil connections on the server motherboard. If the distance between the motherboard connector and the server power connector is too close, various interferences are likely to occur between the motherboard connector and the server power connector, such as interference in position and interference in assembly operations, etc. In order to reduce copper foil connections and in-board current, and to reduce interference and interference, the distance between the motherboard connector and the server power connector needs to be limited within a certain range.

The upper limit value of the target distance range may or may not be used to control the current flow generated between the motherboard connector and the server power connector to be less than or equal to a current flow threshold, and the upper limit value may or may not be 100 mm. The lower limit value of the target distance range may or may not be used to control the interference generated by the motherboard connector on the server power connector to be less than an interference threshold, and the lower limit value may or may not be 2 mm.

The target distance range may or may not be 3 mm - 100 mm. The target distance range may also or may not be 2 mm - 50 mm, or 2 mm - 70 mm, or 3 mm - 50 mm.

[0099] Through the above content, the distance between the server power connector and the motherboard connector is limited within a certain distance range. The setting of this distance range achieves the improvement of power transmission efficiency and reduction of signal interference while ensuring electrical safety.

[0103] Optionally, in the embodiments of the present application, the power supply converter can be, but is not limited to, arranged on the accelerator card extension board.

[0104] Optionally, in the embodiments of the present application, Figure 7 is a schematic diagram of a power supply system according to an embodiment of the present application. Figure 4 As Figure 7 shown, the accelerator card can include, but is not limited to, only the accelerator card extension board (i.e., the Riser board), on which an accelerator card slot and an extension connector can be, but are not limited to, provided. The extension connector is a power connector, and the accelerator card slot is an accelerator card connector. The motherboard connector on the server motherboard is connected to the extension connector board-to-board, the extension connector is connected to the accelerator card connector board-in-board, and the extension connector is also connected to the power supply converter board-in-board.

[0105] Through the above content, the accelerator card only includes the accelerator card extension board, and the accelerator card adapter board is no longer needed, simplifying the complexity of the power supply system.

[0106] As an alternative implementation, a first power supply pin and a second power supply pin are provided on the accelerator card slot; the extension connector is connected to the motherboard connector and the first power supply pin; the extension connector is also connected to the power supply converter, and the power supply converter is connected to the second power supply pin; the first power supply pin is used to obtain the target voltage; the second power supply pin is used to obtain the reference voltage.

[0108] Optionally, in the embodiments of the present application, the first power supply pin in the acceleration card slot can be used for obtaining a target voltage, but is not limited thereto. Specifically, the first power supply pin can be responsible for directly obtaining the target voltage from the expansion connector on the acceleration card expansion board. The target voltage is usually a relatively high DC voltage (such as 12V), which is directly supplied to the core components of the server acceleration card or used for preliminary power distribution. The existence of the first power supply pin ensures that the server acceleration card can directly access the original power provided by the system, reducing energy loss in the intermediate links.

[0109] Optionally, in the embodiments of the present application, the second power supply pin in the acceleration card slot can be used for obtaining a reference voltage, but is not limited thereto. Different from the first power supply pin, the second power supply pin can be responsible for receiving the reference voltage. The reference voltage is a lower voltage obtained by converting the target voltage by a power supply converter, which is more suitable for specific components inside the server acceleration card, such as the computing unit, cache, control circuit, etc. of the GPU.

[0110] Optionally, in the embodiments of the present application, Figure 8 is a schematic diagram of the Figure 7 corresponding power supply system. As Figure 8 shown, the expansion connector can be connected to the motherboard connector, but is not limited thereto. The expansion connector can be connected to the first power supply pin, but is not limited thereto. The expansion connector is also connected to the power supply converter, and the power supply converter is connected to the second power supply pin. The expansion connector can provide the 12V target voltage to the first power supply pin through the 12V_GPU1 / 12V_GPU2 / 12V_GPU3 / 12V_GPU4 power supply link. The power supply converter can obtain the 12V target voltage from the expansion connector, convert the 12V target voltage into a 3.3V reference voltage, and provide the 3.3V reference voltage to the second power supply pin through the 3V3_GPU1 / 3V3_GPU2 / 3V3_GPU3 / 3V3_GPU4 power supply link.

More specifically, the power supply protector may but is not limited to be disposed between the server power connector and the motherboard connector. The power supply protector being disposed on the path between the server power connector and the motherboard connector means that the power supply protector is located in the direct path from the server power input to the acceleration card board output, in a key position where it can effectively monitor and control the power quality.

[0116] Optionally, in the embodiments of the present application, as Figure 3 shown, it may but is not limited to be provided with four power supply protectors on the server motherboard: electronic fuse 1, electronic fuse 2, electronic fuse 3, and electronic fuse 4.

[0133] Through the above content, the power supply protector detects and protects the input power supply on the direct path after the power connector or through the indirect path of the expansion connector, effectively preventing the damage of power abnormal events to the server acceleration card and ensuring the stable operation of the server acceleration card.
