FormulaMod RTX 4070 12VHPWR 16Pin Male to 2x8Pin Female 17.7in White Power Extension Cord

SKU CH-JNK2-099AF

Extends a dual 8-pin cable to a 12VHPWR 16-pin GPU connector for RTX 4070 series cards using 16AWG tinned copper wire in a 17.7-inch white sleeved length

Color White

  • PCIe 5.0 ready 12VHPWR male to dual 8-pin female
  • 16AWG tinned copper core for reliable power delivery
  • 7 inch length adds reach without replacing PSU cables
  • Three included cable combs keep routing tidy
  • Pre-bent nylon-braided jacket resists daily wear

Compatibility and connectors

This extension cable carries a 12VHPWR 16-pin male connector on one end and two 8-pin female connectors on the other. It lets an RTX 4070 or similar graphics card draw power from a supply that only provides dual 8-pin modular leads. The cord is not a PSU replacement and must attach to the existing power cables.

Practical limits of the PCIe 5.0 power interface

The cable follows the PCIe 5.0 power specification with 16AWG tinned copper conductors inside a nylon-braided jacket. Length is fixed at 17.7 inches, so the reach is limited to that distance between the PSU cables and the graphics card. No additional voltage or current ratings are provided beyond the standard.

What to verify before ordering

Confirm that your power supply includes two spare 8-pin PCIe modular cables and that the graphics card uses a 12VHPWR 16-pin socket. The extension adds length but does not change the power delivery capability of the original PSU cables. Ensure the 17.7 inch span suits your case layout and cable routing plans.

Questions about this item

Should I pick the black or the white 17.7‑inch extension for my RTX 4070 build?

Both colours are 17.7 inches long and use the same 16‑pin male to dual 8‑pin female layout, so choose the shade that matches your case interior.

What does the 12+4 pin male connector actually deliver once it is plugged into the graphics card?

The 12+4 pin male end carries up to 16 AWG tinned copper conductors rated for PCIe 5.0 power levels, feeding the GPU through the two 8‑pin female sockets.

Is the PCIe 5.0 label on this cord a hard limit on how much power can pass through?

The cable is built to the PCIe 5.0 12VHPWR specification, so its 16‑pin male and dual 8‑pin female connectors handle the current that standard defines.
