What is a PCI-E power cable and what are the types and functions of PCI-E power cables?

A PCI-E power cable is a connection cable used to provide power to the interface between a power supply and a PCI Express (PCI-E) device. PCI-E (Peripheral Component Interconnect Express) is a high-speed data bus interface used to connect expansion cards to motherboards, and PCI The PCI-E power cable is a component necessary to provide power to PCI-E devices.
PCI-E power cables usually consist of one or more pairs of wires with different plugs and connectors to adapt to different devices and power interfaces. Their function is to provide a stable power supply to PCI-E devices to meet their power requirements for proper operation. The following are some common types of PCI-E power cables and their functions:
6-pin PCI-E power cable: This power cable is usually used to supply PCI-E devices with lower power consumption, such as some older graphics cards or other expansion cards. It contains 6 wires and can provide a maximum power output of 75 watts.
8-pin PCI-E power cable (also known as 6+2-pin PCI-E power cable): This power cable is designed to be flexible and can be inserted into 6 or 8-pin slots to accommodate different devices. It provides higher power output capability and is typically used to supply high power graphics cards and other PCI-E devices.
8-pin PCI-E power cable (also known as 6+2-pin PCI-E power cable) to dual 8-pin PCI-E power cable: This power cable is an extended PCI-E power cable used to supply extremely high power graphics cards, such as some high performance graphics cards or dual graphics card configurations. It can provide higher power output through two separate 8-pin plugs to meet the needs of these devices.
PCI-E Power Splitter: This is a special type of PCI-E power cable that divides a single PCI-E power connection into multiple power output connectors. It is typically used in situations where multiple PCI-E devices are being supplied at the same time, such as multiple graphics card configurations or other expansion cards that require additional power.
The function of PCI-E power cables is to ensure that PCI-E devices receive sufficient power supply to maintain their proper operation and performance. They transmit power to the device through DC power supplied by the power supply to meet its various voltage and power specifications required. PCI-E power cords are designed and specified to be compatible with the device's power consumption and power interface, and to provide stable, efficient power transmission to ensure device reliability and performance.
A PCI-E power cable is a power connection cable used to connect a power supply to a PCI-E device, providing the required power supply. Different PCI-E power cable types and specifications are suitable for devices with different power consumption and ensure that the devices can work properly and perform at their best.
