Pink 12VHPWR 16-pin male to dual 8-pin female sleeved extension cord with cable combs

FormulaMod

FormulaMod 12VHPWR 16‑Pin Male to 2×8‑Pin Female Extension Cord 17.7″ Pink

SKU CH-H8T3-H56KJ

A PCIe 5.0 extension cable with a 12VHPWR 16-pin male connector and dual 8-pin female ends, 17.7 inches long, includes three cable combs for tidy routing

Color Pink

  • Extends GPU power reach with 17.7 inch 12VHPWR male to dual 8-pin female connectors
  • 16AWG tinned copper conductors deliver reliable current for RTX 4070 and 3090 class cards
  • PCIe 5.0 rated 12+4 pin interface supports modern GPU power requirements
  • Three included cable combs enable tidy routing and consistent cable alignment
  • Pre-bent ultra-soft nylon braid resists wear while simplifying installation in tight spaces

12VHPWR Extension for RTX 4070 Ti

This 17.7 inch extension cord connects a 12VHPWR 16-pin male plug to two 8-pin female sockets. It lets builders use existing dual 8-pin modular cables to power compatible RTX 4070 Ti, 4070 or 3090 Ti graphics cards without replacing the power supply. The pink nylon braid adds a distinctive look inside the case. Three cable combs are included for tidy routing.

Sustained Load Behaviour

High quality 16AWG tinned copper conductors carry the load continuously without overheating. The pre-bent design and ultra-soft braided jacket reduce stress on connectors during long gaming or rendering sessions. As an extension, it relies on the host PSU cables for actual power delivery, so stability matches the source cables. Do not plug this directly into the PSU; it must sit between the PSU cables and the GPU.

Compatibility Check

Verify your power supply provides two separate 8-pin PCIe modular cables, not a single daisy-chained run. Confirm the graphics card uses a 12VHPWR 16-pin (12+4) connector. Ensure 17.7 inches of extra length fits your routing path and that the case has room for the combs. This cord is not for GPUs with native 8-pin or 12-pin inputs, nor for direct PSU connection.

Questions about this item

Does the 16‑pin 12VHPWR extension add noticeable heat or power loss when the RTX 4070 runs all day?

The 16AWG tinned copper conductors and short 17.7‑inch length keep resistance low, so the extension adds negligible heat or voltage drop during continuous load.

What existing cables must my power supply already provide for this extender to work?

Your PSU needs two modular 8‑pin (7+1) PCIe cables; the extender plugs into those and presents a single 16‑pin connector to the graphics card.

Will the 12VHPWR extension work reliably with an older RTX 3090 that still uses dual 8‑pin power?

This extender converts dual 8‑pin output to a 16‑pin input, so it is intended for 12VHPWR‑equipped cards such as the RTX 4070; it does not adapt a 3090’s native 8‑pin connectors.
