FormulaMod 16AWG 12VHPWR to 4×8Pin PCIe 5.0 Extension Cable 17.7in Red

SKU CH-ND51-HHQ0R

Extends a 12VHPWR GPU connector to four 8‑pin PCIe 5.0 plugs using 16AWG copper and includes three cable combs for tidy routing

Color Red

  • 16AWG tinned copper wire delivers reliable power to RTX 4090, 4080, 4070 and 3090
  • 12VHPWR male to four 8-pin female connectors adapts modern GPUs to existing PSU cables
  • 7 inch extension adds routing length without replacing the power supply
  • three included cable combs enable tidy, aligned cable runs
  • nylon braided jacket protects conductors from daily wear and tear

Extension for 12VHPWR GPUs

This 12VHPWR male to four 8-pin female extension cable connects an existing dual 8-pin modular PSU cable to a 12VHPWR graphics card. It suits builders upgrading to an RTX 4090, 4080 or 4070 Ti without replacing the power supply. The 16 AWG tinned copper conductors handle the required current for these high-wattage GPUs.

Thermals and power delivery

The 16 AWG tinned copper wire is rated for the power draw of 12VHPWR cards such as the RTX 3090 Ti, 4070 Ti, 4080 and 4090. A durable nylon braided jacket protects the conductors from heat and abrasion during normal operation. The pre-bent, ultra-soft design reduces strain on the connector, helping maintain stable contact and consistent power delivery.

Cable management accessories

Three included cable combs let you align and secure the four 8-pin branches for a clean, uniform look inside the case. The combs simplify routing alongside other sleeved cables and keep the extension tidy without additional ties. This accessory set supports a professional finish for custom-loop or air-cooled builds alike.

Questions about this item

How do I install the 16-pin 12VHPWR extension cable with the four 8-pin connectors?

Connect the four 8-pin male cables from your power supply into the female ends of the extension, then plug the 16-pin male end into the GPU; the three included cable combs align the sleeved wires for a clean route.

What maintenance will the 16AWG tinned copper wire and nylon braid need over time?

The high-density nylon braid resists abrasion, so only occasional dust removal with compressed air is required; check that the pre-bent connectors stay firmly seated after any case moves.

What thermal or current limit appears first when the 17.7-inch extension runs a 4090 under sustained load?

The 16AWG conductors set the ampacity ceiling; monitor connector temperatures during prolonged full-power operation to ensure the crimps and pins stay within safe limits.
