Splitting an 8-pin CPU connector into two 4-pin connectors involves locating the clip or tab that holds the sections together and gently pulling them apart. This is often necessary for compatibility with motherboards that only have a 4-pin power header.
How to Split an 8-Pin CPU Connector?
When assembling or upgrading a PC, proper power supply connections are crucial for the smooth operation of your system. Modern power supply units (PSUs) typically come equipped with an 8-pin CPU power connector, but not all motherboards require or can accommodate all 8 pins.
Some only need a 4-pin connector, making it necessary to split the 8-pin CPU connector.This guide will explain the process of safely splitting an 8-pin CPU connector into two 4-pin connectors, why this is sometimes necessary, and provide essential tips to avoid common mistakes.
Why You Might Need to Split an 8-Pin CPU Connector?
Splitting the 8-pin CPU connector is often necessary when the motherboard only has a 4-pin power header. This connector supplies power directly to the CPU, so it’s important to make sure the correct connection is made. Here are a few scenarios in which you might need to split your 8-pin CPU connector:
- Motherboard Compatibility: Some older or budget motherboards come with only a 4-pin CPU power input. The extra 4 pins on an 8-pin connector are unnecessary and won’t fit, requiring you to split the connector.
- Power Supply Flexibility: Modern PSUs are often built to accommodate multiple configurations, including both 4-pin and 8-pin CPU power setups. Splitting the connector lets you adapt to different motherboard requirements.
- Power Efficiency: Not all CPUs require the full power provided by an 8-pin connector. In some cases, using just 4 pins will suffice and splitting the connector allows you to adjust to the CPU’s needs without overpowering it.
- Easier Cable Management: Splitting the connector can also help with cable management, especially in smaller or more compact PC cases where there’s limited space for cables.
Understanding the 8-Pin CPU Connector:
Before diving into the process of splitting the 8-pin CPU connector, it’s important to understand its basic components and how it works. The 8-pin EPS connector is specifically designed to provide additional power to the CPU, typically consisting of two sections, each with 4 pins.
These sections are often labeled as 4+4, indicating that they can be separated. The pin configuration includes both positive and ground pins, making correct alignment crucial when connecting it to the motherboard. Properly separating these pins helps prevent incorrect connections. Additionally, the motherboard CPU power socket may be a 4-pin, 8-pin, or a 4+4 pin socket, so it’s essential to consult your motherboard manual to determine the correct type before splitting the connector.

Do You Need to Plug in Both 8-Pin CPU Connectors?
Whether you need to plug in both 8-pin CPU connectors depends on your motherboard’s design and power requirements. High-performance motherboards or those designed for overclocking often require both connectors to ensure stable power delivery to the CPU.
- Single 8-Pin Connector: Many motherboards only require a single 8-pin CPU power connector, especially those designed for mainstream CPUs. Plugging in one 8-pin connector should suffice.
- Dual 8-Pin Connectors: High-performance or overclocked systems, particularly those with multiple CPUs or advanced motherboards, may require both 8-pin connectors for stable power delivery. Always check your motherboard’s manual or specifications to determine the exact power requirements.
How Much Power Can Two 8-Pin Connectors Provide?
Two 8-pin CPU connectors can provide a substantial amount of power. Each 8-pin connector can deliver up to 150 watts of power, so with two connectors, the total power capacity can reach up to 300 watts. This is typically sufficient for high-performance CPUs or motherboards with multiple power phases, ensuring stable operation even under heavy loads or overclocking conditions.
It’s important to note that while the connectors themselves can deliver this amount of power, the actual power draw will depend on the specific requirements of your CPU and motherboard. Always ensure that your PSU can provide enough power for your entire system, including all connectors.
How to Remove a Wire from an 8-Pin Connector?
Removing a wire from an 8-pin connector requires careful handling to avoid damaging the connector or wires. Start by identifying the locking mechanism for each pin and gently release it before pulling out the wire.
- Prepare Tools: You may need small tools like needle-nose pliers or a specialized pin extraction tool, depending on the type of connector.
- Identify the Locking Mechanism: Most connectors have a locking tab or clip that secures the wire. Locate this locking mechanism for each pin you want to remove.
- Release the Pin: Gently press or lift the locking tab while carefully pulling the wire out of the connector. Avoid using excessive force to prevent damage to the pins or connector.
- Inspect the Connector: After removal, check the connector and wires for any damage. Ensure that the pin holes are clean and that no debris or bent pins are present.
How to Separate an 8-Pin Connector into 4 Pins?
To separate an 8-pin connector into two 4-pin connectors, first locate the clip or tab that holds the sections together. Gently pull apart the two halves, making sure not to damage the pins or wires during the process.
- Inspect the Connector: Check the 8-pin connector for a clip or hinge mechanism that holds the two sections together. Many modern connectors are designed to split into two 4-pin halves easily.
- Locate the Clip: Find the small clip or tab that keeps the two sections of the connector joined. This is usually a small plastic piece that can be gently pressed or slid to release the halves.
- Separate the Sections: With the clip located, carefully pull apart the two 4-pin sections. Apply gentle pressure to avoid damaging the pins or wires. If the connector is resistant, double-check that you are not forcing it and that you are pressing the clip correctly.
- Check the Pins: After separating, inspect the pins to ensure none are bent or damaged and that both sections are clean and intact.

Can You Plug an 8-Pin CPU Connector into a 4-Pin Socket?
No, you cannot directly plug an 8-pin CPU connector into a 4-pin CPU power socket. The 8-pin connector typically provides additional power and is designed for motherboards that support higher power delivery or multiple CPUs.
While the 8-pin and 4-pin connectors are similar, they are not interchangeable due to differences in power requirements and pin configurations. However, if you have an 8-pin connector and your motherboard only requires a 4-pin connector, you can use only the 4-pin part of the 8-pin connector. Ensure that the unused 4-pin portion is secured and does not interfere with other components or airflow.
Common Mistakes to Avoid When Splitting an 8-Pin CPU Connector:
- Using the Wrong Connector: Don’t confuse the 8-pin CPU power connector with an 8-pin PCIe connector, which is used to power graphics cards. These connectors look similar but have different pin arrangements and functions.
- Forgetting Power Requirements: If your motherboard supports both 4-pin and 8-pin configurations and you’re running a powerful CPU, it’s often better to use the full 8-pin connector for more reliable power delivery under load.
- Poor Cable Management: Leaving unused connectors loose inside the case can obstruct airflow and cause clutter. Always ensure proper cable management for a clean build
Safety Tips for Splitting an 8-Pin CPU Connector:
When splitting an 8-pin CPU connector, never force the connection as it could damage the pins or wires. Always check your motherboard’s manual to confirm whether a 4-pin or 8-pin power input is required. Handle the connectors gently to avoid bending or breaking the pins. Lastly, ensure the unused half is properly secured to prevent it from interfering with airflow or other components.
- Don’t Force It: If the connector doesn’t split easily, stop and double-check to ensure it’s meant to be separated. Forcing it could damage the connector or the motherboard socket.
- Check Power Requirements: Always consult your motherboard’s manual to confirm whether it requires a 4-pin or 8-pin power connection. Some high-performance motherboards need the full 8-pin power for stable operation, especially when overclocking.
- Handle with Care: The pins in your CPU power connectors are delicate. Always handle them gently to prevent bending or damaging the pins or the socket on your motherboard..
