What is a Power Supply Cable for CPU?

The power supply cable for CPU, also known as the CPU power cable or CPU power connector, is an essential component in a computer system that provides the necessary power to the central processing unit (CPU).

This cable connects the power supply unit (PSU) to the motherboard, ensuring that the CPU receives a steady and reliable power supply. It is responsible for supplying the processor with the necessary voltage and current to operate efficiently.

The power supply cables for CPU come in different forms, including the 4-pin CPU power cable, 8-pin CPU power cable, and 24-pin ATX power cable. These cables vary in terms of their design, connector type, and power delivery capabilities.

In this article, we will explore the different types of power supply cables for the CPU, their functions, compatibility, and the importance of choosing the right cable for your system.

Types of Power Supply Cables for CPU

The power supply cables for CPU can differ based on the connector type, pin configuration, and power delivery. The most commonly used power supply cables for CPU are:

• 4-pin CPU Power Cable
• 8-pin CPU Power Cable
• 24-pin ATX Power Cable

4-pin CPU Power Cable

The 4-pin CPU power cable, also known as the P4 connector, is a power cable designed specifically for older motherboards and processors. It provides supplemental power to the CPU and ensures stable operation.

This cable consists of a 4-pin female connector and a 4-pin male connector. The female connector attaches to the motherboard's 4-pin ATX12V connector, while the male connector plugs into the PSU's 4-pin peripheral connector.

The 4-pin CPU power cable delivers +12V power to the CPU, supplying the necessary voltage for the processor to function properly. This cable is commonly used in systems with lower power requirements and can be found in many older computers.

It is important to note that some modern motherboards may not have a 4-pin ATX12V connector and instead rely on an 8-pin CPU power cable. In such cases, an adapter can be used to convert the 4-pin connector to an 8-pin connector for compatibility.

8-pin CPU Power Cable

The 8-pin CPU power cable, also known as the EPS connector, is a power cable designed for modern motherboards and high-performance CPUs. It provides a higher power delivery compared to the 4-pin CPU power cable.

This cable consists of an 8-pin male connector that attaches directly to the motherboard's 8-pin EPS connector and plugs into the PSU's 8-pin peripheral connector or EPS connector.

The 8-pin CPU power cable supplies both +12V and +5V power to the CPU, ensuring stable and efficient operation, especially for power-hungry processors. It delivers a higher current compared to the 4-pin CPU power cable, making it suitable for high-performance systems.

24-pin ATX Power Cable

The 24-pin ATX power cable, also known as the main power connector, is responsible for supplying power to various components on the motherboard, including the CPU. It is a crucial cable that ensures the entire system receives the necessary power.

This cable consists of a 24-pin male connector that attaches directly to the motherboard's 24-pin ATX power connector and plugs into the PSU's 24-pin ATX connector.

The 24-pin ATX power cable provides +3.3V, +5V, and +12V power to the CPU and other components, ensuring stable voltage regulation and efficient operation. It is a standard cable found in most modern computer systems.

Other Power Supply Cables for CPU

In addition to the 4-pin CPU power cable, 8-pin CPU power cable, and 24-pin ATX power cable, there are other power supply cables that are less common but may be necessary depending on the specific system requirements. Some of these cables include:

• 6-pin CPU power cable: This cable is designed for specific motherboards and CPUs that require additional power beyond the traditional 4-pin or 8-pin connections.
• 8-pin CPU power extension cable: This cable is used when the standard 8-pin CPU power cable is not long enough to reach the PSU or requires additional flexibility for cable management.
• Splitter cables: These cables allow you to split a single 4-pin or 8-pin CPU power connector into multiple connectors, providing power to multiple components.

Importance of Choosing the Right Power Supply Cable for CPU

Choosing the right power supply cable for the CPU is crucial for the overall stability, performance, and longevity of your computer system. Here are a few reasons why:
