EPS 8-Pin and PCIe 8-Pin Extension Kit

This kit provides one 18AWG EPS 8-pin extension and one PCIe 8-pin extension, each three feet long. It is intended for builders who need extra reach between the power supply and the motherboard or graphics card. The female-to-female connectors attach directly to existing PSU cables without tools.

Heat-Shrink-Less Sleeved Cables with Combs

Thick 18AWG wires run inside a high-density flexible sleeve that holds shape while remaining adaptable. A heat-shrink-less design avoids bulky ends, and the included cable combs keep individual wires aligned for a clean internal layout. Connectors use a Male 5557 to Female 5559 interface.

Rated for 12 V DC Power Delivery

The extensions carry 12-volt direct current through 16- and 30-amp rated conductors suited to typical CPU and GPU loads. The premium sleeving adds minimal electrical resistance and does not trap heat under normal operation. No active cooling or additional power overhead is introduced by the cables.
