FormulaMod 16Pin to 3x8Pin PCI-E 5.0 Extension Cable Blue 17.7 inch

SKU CH-4DJ7-ZWANT

Extends a 12VHPWR GPU connection using three 8-pin PSU cables, 17.7 inches long with braided sleeving and cable combs for tidy routing

Color Blue

  • Extends 16-pin GPU power from three 8-pin PSU connectors
  • 7-inch length adds routing flexibility inside the case
  • High-density 16AWG tinned copper ensures reliable current delivery
  • Durable nylon braided jacket resists daily wear and tear
  • Includes three cable combs for clean, organised cable management

16Pin PCIe 5.0 Extension for RTX 3090/4080/4090

This cable extends the 12VHPWR connection on RTX 3090 Ti, RTX 4080 and RTX 4090 graphics cards using three 8-pin PCIe sources. It is built for builders who need extra reach between the power supply and the GPU without replacing the existing PSU cables.

Pre-bent 16AWG tinned copper

The ultra-soft, pre-bent design and included cable combs make routing straightforward and keep the three 8-pin branches tidy. Installers must remember this is an extension only; it connects to existing modular PSU cables and must not be plugged directly into the power supply.

Check PSU modular 8-pin outputs and case clearance

Verify that your power supply provides enough 8-pin PCIe connectors for the three female ends and that the 17.7 inch length fits your chassis routing path. The cable uses 16AWG tinned copper under a durable nylon braided jacket for reliable power delivery.

Questions about this item

How can I confirm the 16-pin 12VHPWR extension is seated correctly after routing the 17.7 inch cable?

Verify the 12+4 male connector clicks fully into the GPU socket and each 8-pin female end locks onto the PSU cables; the pre-bent design and included combs keep the 16AWG tinned copper wires aligned for stable PCIe 5.0 power delivery.

What ships with the FormulaMod extension and what must I already own?

The box contains one 16-pin male to three 8-pin female sleeved extension cable plus three cable combs; you must supply a modular PSU with three native 8-pin PCIe outputs — do not plug the extension directly into the PSU.

Which GPU models does the blue 17.7 inch 16-pin to triple 8-pin extension support?

The cable is built for RTX 3090 Ti, RTX 4090 and RTX 4080 series cards that use the 12VHPWR 12+4 connector, extending the existing PSU cables by 17.7 inches.
