Green 12VHPWR 16-pin male to dual 8-pin female sleeved extension cable with combs, 17.7 inch length

FormulaMod

FormulaMod 12VHPWR 16Pin to 2x8Pin Extension Cable 17.7 Inch Green

SKU CH-SKWY-RTTP0

A 17.7-inch PCIe 5.0 extension cable converts a 12VHPWR 16-pin male connector to two 8-pin female plugs using 16AWG tinned copper wire and includes three cable combs for tidy routing

Color Green

  • Extends GPU power reach with 17.7 inch PCIe 5.0 cable
  • 16-pin 12VHPWR male connects to dual 8-pin female for RTX 4070 Ti compatibility
  • High-density 16AWG tinned copper wire ensures stable current delivery
  • Pre-bent nylon-braided jacket with three combs enables tidy cable routing
  • Extension design works with existing PSU cables for simple installation

RTX 4070Ti 12VHPWR Extension

This FormulaMod extension cable connects a dual 8-pin modular PSU lead to the 16-pin 12VHPWR connector on an RTX 4070Ti graphics card. It adds 17.7 inches of reach so the factory cable can route cleanly behind the motherboard tray. The 16AWG tinned copper conductors are wrapped in a durable nylon braid for long service life. Three included cable combs keep the wires aligned for a tidy interior.

Thermals and Power Delivery

The 16AWG copper wire handles the current required by the PCIe 5.0 12VHPWR specification without adding measurable resistance. Nylon braiding insulates the conductors and resists abrasion during routine case maintenance. Because the cable is passive, it introduces no active cooling requirements or audible noise. The pre-bent design reduces strain on the GPU connector during normal operation.

Build Integration

This extender is designed for builders who already own a modular power supply with dual 8-pin PCIe outputs and want to avoid a PSU replacement. It plugs between the existing PSU cables and the graphics card, freeing the short factory leads from tight bends. The green sleeving and combs support a unified colour scheme. It is not suited for non-modular PSUs or systems lacking dual 8-pin PCIe connectors.

Questions about this item

How do I install the 12VHPWR 16-pin male connector onto the RTX 4070 GPU without bending the pins?

Align the 16-pin male connector squarely with the GPU socket and press straight in until the latch clicks; the pre-bent cable route and included combs keep the 16AWG wires from pulling the plug sideways during routing.

Will the nylon braided jacket or 16AWG tinned copper wires need replacement after repeated case openings?

The high-density nylon braid resists abrasion from panel edges and the tinned copper cores resist oxidation, so neither the jacket nor the conductors require scheduled replacement under normal desktop use.

At what point does the 17.7-inch extension length become the limiting factor for stable PCIe 5.0 power delivery?

The 17.7-inch 16AWG run adds minimal resistance; the first limit under sustained load is usually the PSU’s native 8-pin cable gauge or connector contact resistance, not this extender.
