Optionally, the inter-board connection can be, but is not limited to, implemented via various flexible cables or various rigid cables.

[0034] Optionally, in the embodiments of the present application, a rigid cable, also known as a hard wire, generally refers to a relatively rigid, non-bending wire or cable that provides a stable, direct power and signal transmission path for connections within the server.

Power converters play an important role in a variety of situations, particularly in accelerator card power supply systems. Power converters may be used to convert a target voltage received from a server motherboard into the voltage required by the server accelerator card. Power converters may not only regulate voltage but also provide additional functions such as current limiting, overheating protection, and short-circuit protection to ensure the safe and stable operation of the entire power supply system. There are various types of power converters, which can be primarily categorized into the following based on their operating principles and technical characteristics: Linear Voltage Regulators (Linear Voltage Regulators): These converters continuously adjust the output voltage to provide a stable power supply. They have a simple structure but relatively low efficiency and are typically used in applications requiring high-precision voltage regulation. Switching Power Supply Converters (Switching Power Supply Converters): Switching power supply converters utilize switching technology to convert the input voltage into the desired output voltage. These converters are highly efficient and suitable for applications requiring high-efficiency conversion. Switching power converters can be further subdivided into PWM (pulse width modulation) controllers, DC-DC converters (direct current to direct current converters), and AC-DC converters (alternating current to direct current converters). DC-DC converters are used to convert DC voltage to another DC voltage, for example, converting a 12V input to a 5V (volt) or 3.3V output. AC-DC converters are used to convert AC voltage to DC voltage. In the power supply design of the accelerator card, DC-DC converters, a type of switching power converter, can be used, but are not limited to, because DC-DC converters provide high-efficiency, high-density power conversion, good thermal management, and flexible configuration capabilities.

Specifically, the first power pin can be used, but is not limited to, to directly obtain the target voltage from the power connector on the accelerator card adapter board. The target voltage is typically a higher DC voltage (such as 12V) to directly power the core components of the server accelerator card or for initial power distribution. The presence of the first power pin ensures that the server accelerator card can directly access the raw power provided by the system, reducing energy loss in the intermediate links.

[0062] Optionally, in an embodiment of the present application, the second power supply pin in the accelerator card slot can be used, but is not limited to, to obtain a reference voltage. Unlike the first power supply pin, the second power supply pin can be used, but is not limited to, to receive a reference voltage. The reference voltage is a lower voltage converted from the target voltage by a power converter, and is more suitable for specific components within the server accelerator card, such as the GPU's computing unit, cache, and control circuits. This voltage conversion and distribution mechanism ensures that the server accelerator card receives an appropriate and stable power supply in different operating modes, thereby improving the operational stability and performance of the server accelerator card.

[0063] Through the above content, by distinguishing the first power supply pin and the second power supply pin, accurate power supply to different components of the server accelerator card can be achieved, avoiding voltage overload or insufficient, thereby improving power supply efficiency and system stability.

The second power pin is different from the first power pin and may be used, but is not limited to, to receive a reference voltage. The reference voltage is a lower voltage converted from the target voltage by a power converter, and is more suitable for specific components within the server accelerator card, such as the GPU's computing unit, cache, and control circuit.

[0110] Optionally, in the embodiment of the present application, Figure 8 is with Figure 7 Schematic diagram of the corresponding power supply system. Figure 8 As shown, the expansion connector can be, but is not limited to being connected to the motherboard connector, the expansion connector can be, but is not limited to being connected to the first power pin, the expansion connector can also be connected to a power converter, and the power converter can be connected to the second power pin.

A transient voltage suppressor diode is a fast-response protection device that can quickly clamp the voltage within a safe range when transient voltages (such as voltage spikes caused by lightning strikes or power switching) occur in the power system, protecting the back-end circuits from damage. An E-Fuse is a programmable power management component that can detect overcurrent or short-circuit events and disconnect the circuit when necessary to prevent further damage.

[0131] Alternatively, a direct connection path involves connecting the power connector directly to the power protector, which performs preliminary safety checks and protection on the directly input power. The power protector connects to the first power pin on the accelerator card expansion board via an expansion connector, providing initial power to the accelerator card. The power protector also connects to a power converter, which converts the input power into a form suitable for the server accelerator card. The converter then connects to the second power pin via an expansion connector to provide the converted power.
