Technical Field

In the related art, power supply of the board card is often limited, for example, the maximum value of power supply for the board card is limited, for example, taking the board card as a PCIe card as an example, the maximum power supply of PCIe Slot of power supply for the PCIe card is 75W, most of power consumption of the board card can be controlled in the range, and only PCIe Slot power supply is used to meet the requirement, but as power consumption of the board card increases, the 75W scene cannot meet the use requirement.
One way in the related art is to use PINs such as JTAG1, JTAG2, JTAG3, etc. on PCIe Slot as P12V to additionally power the board, but this sacrifices the effect of the JTAG PINs, which must be used in some scenarios; at the same time, this approach also changes the hardware design on PCIe Slot. Another way in the related art is to add an additional power connector, and then manually divide the power consumption of the board card, with a part being powered by PCIe Slot and a part being powered by the additional power connector. The power connector in this way is usually packaged larger, occupies a very large area of the board PCB (Printed Circuit Board ), and is particularly limited in layout because the general network card is generally fixed in length and width; in addition, in this way, the power connector is necessary, and if not used, the board card cannot work normally.

Detailed Description
Embodiments of the present application will be described in detail below with reference to the accompanying drawings in conjunction with the embodiments.
It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.
First, terms and nouns referred to in the various embodiments of the present application are explained as follows:
PCIe card, peripheral Component Interconnect Express Card; PCIe (Peripheral Component Interconnect Express) Slot is an interface for connecting to an expansion card, and is generally used for inserting hardware devices such as a video card, a sound card, a network card, etc. into a server motherboard. PCIe has higher bandwidth and better stability than PCI interfaces, can support higher performance devices, and can transmit multiple data streams simultaneously. The PCIe interface has different versions and speed classes, such as PCIe 1.0, PCIe 2.0, PCIe 3.0, PCIe 4.0, and PCIe 5.0, each with slightly different bandwidths and transmission speeds, and the user needs to select the appropriate version according to his own needs. When installing PCIe expansion cards, it is necessary to ensure that the interface versions and speeds of the server motherboard and expansion card are compatible.
PCIe card (Peripheral Component Interconnect Express Card) is an expansion card for insertion into a server motherboard that provides high-speed data transfer and the ability to connect to external devices. The power supply of PCIe cards is an important factor in ensuring their proper operation. The power supply is typically provided by PCIe slots on the server motherboard, which are connected to the power supply unit by circuitry. The power supply process comprises two key parameters: voltage and current. The PCIe specification defines different versions of slots and their corresponding power consumption and standardized power supply specifications. According to the PCIe specification, the standard power supply capability of a single PCIe slot is 75 watts, meaning that the power supply provided through the slot cannot exceed 75 watts. This provision is intended to ensure the stability and safety of the system.
When a PCIe card is inserted, the motherboard may provide the required power to the PCIe card through pins of the slot. Typically, PCIe slots provide voltages of 3.3V, 12V, or both. Different types of PCIe cards may require different voltages, and therefore manufacturers may design PCIe cards to different specifications.
Furthermore, the power supply of PCIe cards also involves current. PCIe slots can provide some current to meet the power consumption required for normal board operation. The specific current limit depends on the specification of the PCIe slot and is also limited by the server motherboard design and power supply unit capabilities.
It should be noted that different types of PCIe cards may differ in power requirements. Devices such as high performance AI accelerator cards may require a higher power supply and thus may require additional power connections such as a power interface or power harness connection alongside the PCIe slot.
