Two black 12-inch CPU power extension cables with 8-pin female to 4+4-pin male connectors

SMUGDESK

SMUGDESK CPU 8 Pin EPS Extension Cable 12 Inches 2 Pack

SKU CH-4JPY-9DNCB

Two 12-inch EPS cables extend the motherboard CPU power connector with detachable 4+4-pin plugs for flexible routing

  • Extends motherboard CPU power with standard ATX EPS pinout
  • 12‑inch length per cable for flexible routing in custom builds
  • Two‑pack covers multi‑cable wiring needs in one purchase
  • High‑purity copper conductors minimise voltage drop under heavy CPU load
  • Detachable 4+4‑pin male connector fits both 8‑pin and split 4‑pin PSU ports

CPU EPS Extension for Motherboard Power

This 12-inch cable extends the ATX 12 V EPS connection from the power supply to the motherboard CPU socket. It is built for system builders who need extra reach when routing power behind large coolers or in spacious chassis. The pack contains two cables so both primary and secondary CPU connectors can be extended simultaneously.

Female 8 Pin to Detachable 4+4 Pin Male

The connector splits into two 4-pin halves, matching power supplies that provide separate 4-pin CPU plugs. Align the yellow and black wires with the motherboard keying before pressing the locking tabs until they click. Forcing the wrong orientation or confusing this EPS cable with a PCIe GPU cable will prevent the system from starting and can damage components.

High-Purity Copper Conductors Under Load

Oxygen-free copper cores keep resistance low so voltage remains stable when the processor draws sustained current during rendering, compilation or stress tests. The flexible jacket allows tight bends without kinking, maintaining consistent contact through thermal cycles. The cable is not intended for graphics-card power delivery.

Questions about this item

How can I verify the extension cable is delivering stable power to the CPU after installation?

The system should POST and run stress tests without unexpected shutdowns or voltage warnings in BIOS monitoring, confirming the high-purity copper conductors are maintaining steady delivery under load.

What connectors are included in the two-pack and is a separate power supply adapter needed?

Each pack contains two cables with an 8-pin female end and a detachable 4+4-pin male end that plugs directly into standard EPS ports on the power supply; no extra adapter is required.

Which version should I choose if my power supply uses separate 4-pin CPU ports instead of a single 8-pin?

The detachable 4+4-pin male connector splits to fit both unified 8-pin and dual 4-pin EPS headers, so this single version covers either layout.
