Black sleeved 12VHPWR 16-pin male to dual 8-pin female extension cord with cable combs, 17.7 inches

FormulaMod

FormulaMod RTX 4070 12VHPWR 16 Pin Male to 2x8 Pin Female 17.7in Power Extension Cord

SKU CH-4YF8-G96H5

Extends a dual 8-pin PSU cable to a 16-pin GPU connector with 17.7 inches of 16AWG sleeved wiring and three cable combs

Color Black

  • PCIe 5.0 ready 12VHPWR connector powers RTX 4070 cards
  • 16-pin male to dual 8-pin female extends existing PSU cables
  • 16AWG tinned copper with nylon braid delivers reliable current flow
  • Three included cable combs keep routing tidy and organised
  • 7-inch pre-bent length adds slack without excess bulk

Compatibility

This extension cable connects a 12VHPWR 16-pin male connector to two 8-pin female connectors. It supports RTX 4070 series graphics cards that require the 12VHPWR interface. The 17.7-inch length adds reach between the power supply cables and the GPU. Builders adapting an existing dual 8-pin modular cable for a newer card will use this adapter.

Sustained delivery

High-quality 16AWG tinned copper wire carries the load under continuous operation. The durable nylon braided jacket protects the conductors from abrasion and heat over time. Three included cable combs keep the wires aligned, reducing stress on the connectors during long gaming or compute sessions. The pre-bent design maintains stable contact without sharp bends that can degrade performance.

Pre-install checks

Verify your power supply provides two separate 8-pin PCIe modular cables, not a single daisy-chained cable. Confirm the GPU side uses a 12VHPWR 16-pin (12+4) receptacle. This is an extension only; do not plug the male end directly into the PSU. Ensure the 17.7-inch length fits your routing path without tension on either connector.

Questions about this item

Does the 16-pin 12VHPWR connector on this extension cable get warm during sustained RTX 4070 loads?

The cable uses 16AWG tinned copper wire and a high-density nylon braid, materials chosen to handle continuous current with minimal heat buildup.

My PSU only has dual 8-pin PCIe outputs — will this FormulaMod extender connect directly to them?

Yes, the male 16-pin (12+4) end plugs into the graphics card while the two female 8-pin (7+1) ends accept your existing modular PSU cables.

Will the 17.7-inch length and included combs let me route this cleanly alongside an older 8-pin GPU power cable in the same case?

The 17.7-inch reach plus three cable combs give enough slack and organisation to run the extension neatly next to legacy power leads.
