Overview

Does your high-performance build require additional CPU power? Are you building with a Corsair modular power supply and need a dedicated CPU cable? This 8-pin male to 4+4 pin male EPS-12V adapter cable is the perfect solution for providing clean, dedicated power to your motherboard's CPU socket .

Designed exclusively for Corsair modular power supplies, this cable bridges the gap between your PSU's CPU output port and your motherboard's EPS-12V power connector, ensuring your processor receives stable, reliable power for overclocking and demanding workloads .

Why You Need This Cable

Many modern motherboardsespecially those designed for overclockingoften require more CPU power than a single 4-pin connector can provide. High-end boards frequently feature 8-pin or even 8+4-pin CPU power configurations . This cable allows you to:

Add a second CPU power cable for motherboards with dual EPS-12V connectors

Replace a lost or damaged cable from your Corsair PSU kit

Extend your existing CPU power reach for better cable management in larger cases

Ensure stable power delivery during overclocking sessions or under heavy CPU loads

Versatile 4+4 Detachable Design

The motherboard end of this cable features an innovative detachable 4+4 pin design. This means :

Slide together for use as a standard 8-pin EPS-12V connector (compatible with most modern motherboards)

Separate into two 4-pin sections for use as a 4-pin ATX connector (compatible with older or entry-level boards)

No adapters neededsimply configure the connector to match your motherboard's requirements

Premium Build Quality

Conductor: High-purity 18AWG tinned copper wire ensures maximum conductivity and minimal power loss, supporting high-current CPU loads

Insulation: Durable PVC insulation with UL1007 rating provides excellent protection against heat and abrasion

Connectors: Precision-molded 8-pin male (PSU end) and 4+4 detachable male (motherboard end) connectors ensure secure, tight fit with no wobbling or loose connections

Length: 25 inches (63cm) including connectorsoptimized for comfortable routing in most PC cases

3. VERIFY YOUR PSU MODEL

Before purchasing, please locate the model number on your power supply's label and confirm it appears in the compatibility list . Connecting this cable to an incompatible PSU will result in:

Short circuits

Motherboard damage

Component failure

Voided warranties

4. INSTALLATION PRECAUTIONS

Always power down your system and unplug from wall outlet before installation

Ensure proper alignmentconnectors should slide in easily without forcing

Double-check that you're plugging into the correct PSU port (CPU/ATX, not PCI-E)

The 8-pin end and 4+4 pin end cannot be used interchangeably

If you are unsure whether this cable supports your specific power supply model, please contact us through Amazon with your PSU model number before ordering. We're happy to verify compatibility for you .
