SKU CH-A380-B0X54

Extends a 12VHPWR GPU connection using two 8-pin cables with 17.7-inch sleeved length and included combs for tidy routing

Color Blue

  • Extends GPU power reach by 17.7 inches for flexible routing
  • 16AWG tinned copper conductors deliver stable current to RTX 4070 cards
  • 12VHPWR 16-pin male splits to dual 8-pin female for PSU compatibility
  • Nylon-braided jacket with pre-bent design resists daily wear and tear
  • Three included cable combs enable clean, unified cable management

PCIe 5.0 12VHPWR Extension for RTX 4070

This extension cord adapts a 16-pin 12VHPWR male connector to two 8-pin female sockets, enabling RTX 4070 series graphics cards to draw power from existing dual 8-pin modular cables. It is intended for builders upgrading to a 12VHPWR GPU without replacing their current power supply. The 17.7-inch length provides additional routing flexibility inside the case.

Cable Combs and Braided Sleeving Aid Routing

Three included cable combs clamp the individually sleeved wires into a uniform ribbon, simplifying clean cable management and a consistent visual appearance. The pre-bent design and ultra-soft nylon braid reduce stiffness, making it easier to shape the extension around tight corners without kinking. High-density 16 AWG tinned copper conductors maintain stable power delivery across the extended run.

Verify PSU Modular Ports

Confirm your power supply offers two spare 8-pin PCIe modular outputs and that the cables reach the extension's intended mounting point. This product is an extension only; it must not be plugged directly into the PSU. Builders using a single 8-pin cable or a non-modular unit cannot use this adapter. Ensure the 17.7-inch length suits your chassis layout without excessive slack or tension.

Questions about this item

Will the 16AWG tinned copper wires or the nylon braided jacket need replacement after extended use?

The 16AWG tinned copper wire and high-density nylon braid are built for durability and daily wear, so no scheduled replacement is required under normal operation.

What is the first limit reached when the 12VHPWR 16-pin male connector runs at full load for long periods?

The cable is rated for PCIe 5.0 power delivery through its 12+4 pin male to dual 8-pin female design, so the connector specification itself sets the sustained-load ceiling.

Does the 17.7-inch extension add noticeable heat or electrical resistance during all-day gaming?

The high-quality 16AWG tinned copper keeps resistance low, and the ultra-soft pre-bent design with included combs maintains airflow, so added heat is minimal in typical builds.
