What is a computer power harness? What are the types of computer power harnesses?

A computer power harness is a collection of wires and cables used to connect a power supply unit (PSU) to a computer's motherboard, graphics card, hard disk, and other components. They serve to supply and transmit power and signals to provide the computer with the required power and data connections. There are many types of computer power harnesses, the following are some common types of computer power harnesses: 1. Main Power Harness (Main Power Cable): The main power harness is an important harness that connects the power supply and the motherboard, usually using ATX or EPS standards. It includes the main power connector, such as 24-pin or 20+4-pin main power connector, which is used to provide the main power required by the motherboard.2. CPU Power Cable: The CPU power cable harness is the harness that connects the power supply to the CPU socket, usually with a 4+4-pin or 8-pin connector. It provides a stable power supply for the CPU to ensure that the CPU operates normally.3. Graphics Card Power Cable: The Graphics Card Power Cable is used to provide power for the discrete graphics card. Common connectors include 6-pin, 8-pin, or 6+2-pin PCI-E connectors. High-power graphics cards may require more than one power harness to supply power.4. Storage Device Power Cable: Storage device power harnesses are used to provide power to storage devices such as hard disk drives (HDDs) and solid state drives (SSDs). Common connectors include SATA power connectors and Molex power connectors.5. Fan Power Cable: The fan power cable is used to provide power to the fan inside the computer. Usually use 3-pin or 4-pin connector, can be connected to the motherboard or power supply. 6. Front Panel Power Cable: Front Panel Power Cable is used to connect the front panel of the computer's power button, reset button, LEDs and other components to the motherboard. 7. Data Cables: In addition to power supply harnesses, computer Data Cables: In addition to the power supply harness, the computer power harness also includes a data harness, which is used to transmit data signals. Common data harnesses include SATA data harnesses, USB harnesses, audio harnesses, etc. 8. Other Auxiliary Harnesses: There are some other auxiliary harnesses, such as expansion card power harnesses, harnesses between the power supply and the fan controller, and LED light strip harnesses. The selection and combination of these computer power harness types depends on the computer configuration and requirements. Different computer builds and usage scenarios may require different types of power harnesses for power supply and data connection requirements. Therefore, depending on individual needs, computer users can choose the appropriate power harness configuration to ensure proper operation and stability of their computers.
