Sky-blue and white braided 16AWG extension cable with 12VHPWR male to four 8-pin female connectors and three cable combs

FormulaMod

FormulaMod 16AWG 12VHPWR to 4x8Pin PCIe 5.0 Extension Cable 17.7in Sky-blue+White

SKU CH-V2GB-8VC2R

16AWG extension adapts a 12VHPWR 12+4 pin male to four 8-pin female connectors for RTX 4090 4080 4070 3090 GPUs with 17.7 inch sleeved length and three cable combs

Color Sky-blue+White

  • 12VHPWR male to four 8-pin female connectors
  • 16AWG tinned copper wire for stable power delivery
  • 7 inch length extends reach inside the case
  • Three cable combs included for tidy routing
  • Nylon braided jacket protects against daily wear

12VHPWR Extension for RTX 40 Series

This 16AWG extension cable connects a 12VHPWR male plug to four 8-pin female connectors. It lets builders use existing dual 8-pin modular cables from a power supply to run RTX 4090, 4080 or 4070 graphics cards. The 17.7 inch length adds reach without replacing the PSU. Three included combs keep the sleeved wires aligned for a tidy look.

PCIe 5.0 Power Delivery Limits

The cable follows the PCIe 5.0 12VHPWR specification with 12 power pins and 4 sense pins. It is rated for 16AWG tinned copper conductors inside a nylon braided jacket. The design is an extension only; it must not be plugged directly into the PSU. Total current capacity is defined by the source cables and the GPU’s own power target.

17.7 Inch Reach and Four Connector Headroom

At 17.7 inches the cable bridges the gap between a PSU’s modular panel and a top-mounted GPU. Four 8-pin females give flexibility for PSUs with multiple PCIe outputs. Builders needing longer runs or a single 12VHPWR source cable will find the length fixed and the connector count fixed.

Questions about this item

Should I pick the 17.7 in length or a different size for my build?

The cable is supplied at 17.7 in, so choose it if that reach fits the gap between your PSU’s 8‑pin outputs and the GPU’s 12VHPWR socket.

What does the 16 AWG rating mean once the cable is installed?

16 AWG tinned copper conductors keep resistance low, so the extension delivers stable current to the graphics card without noticeable voltage drop.

How does the PCIe 5.0 12VHPWR connector limit power in practice?

The 12 + 4 pin male plug follows the PCIe 5.0 12VHPWR specification, letting a compatible GPU draw its rated power through the four 8‑pin female sockets.
