What is the motherboard power cable? What are the types and functions of motherboard power cords?

A motherboard power cable is a cable used to connect a power supply unit (PSU) to a computer's motherboard to provide the required power supply to the motherboard. It is one of the key power components in a computer system and is responsible for transferring electrical power from the PSU to various circuits and components on the motherboard to ensure proper operation of the computer.
The main types and functions of the motherboard power cord include the following:
1. Main power cable (ATX Power Connector): The main power cable is the primary power connection interface on the motherboard, usually a 20+4 pin or 24 pin connector. It provides the main power supply to the motherboard, including +3.3V, +5V, +12V and other voltages. The main power connector is responsible for providing power to various components on the motherboard, such as the processor, memory, expansion cards, etc.
2. CPU Power Connector: The CPU Power Connector is a connection cable used to supply power to the processor, usually a 4-pin or 8-pin connector. The processor has a high demand for power, and the CPU power connector transfers power to the processor through a special connection interface to meet the processor's power requirements.
3. PCI-E power connector (PCI-E Power Connector): The PCI-E power connector is used to supply power to PCI-E expansion cards, such as graphics cards. This cable is usually a 6-pin, 8-pin or 8+6-pin connector that provides additional power supply to expansion cards such as high-performance graphics cards to meet their power needs.
4. SATA power cable (SATA Power Connector): SATA power cable is used to connect storage devices such as hard drives, CD-ROM drives, etc.. It is usually a 15-pin connector that provides +3.3V, +5V and +12V voltages to storage devices to ensure their proper operation.
5. MOLEX power cable (Molex Power Connector): MOLEX power cable is a universal power connection cable, often used to connect auxiliary devices such as fans, LED lights, etc.. It is usually a 4-pin or 4+4-pin connector that provides voltages such as +5V and +12V to these devices.
The function of these motherboard power cords is to provide a stable and reliable power supply to the motherboard and other devices to ensure the proper functioning of the computer. They transfer power from the power supply to the individual components and devices through the appropriate connection connectors to meet their power consumption requirements. At the same time, these power cords must also have good electrical performance and safety to ensure the quality and safety of the power delivery.
Choosing the right motherboard power cord requires consideration of the power needs of the motherboard and other devices, as well as the requirements for power transfer performance, reliability and security. In addition, attention needs to be paid to the type and specifications of the power connector to ensure that it matches the connection interface of the motherboard and other devices.
