White sleeved 16-pin to triple 8-pin PCIe 5.0 extension cable with combs

FormulaMod

FormulaMod 16Pin (12+4) to 3x8Pin PCIe 5.0 Extension Cable 17.7in White

SKU CH-6ZXQ-Q3J92

Extends a 16-pin PCIe 5.0 GPU connector to three 8-pin cables with 17.7-inch length and included cable combs for tidy routing

Color White

  • Extends reach by 17.7 inches for flexible GPU placement
  • 16-pin 12VHPWR male to three 8-pin female connectors
  • High-density 16AWG tinned copper ensures reliable power delivery
  • Durable nylon braided jacket resists daily wear and tear
  • Includes three cable combs for clean, organised routing

Connector layout

This extension cable carries a 16-pin 12VHPWR male connector on one end and three 8-pin PCIe female connectors on the other. It is built for RTX 3090 Ti, 4080 and 4090 graphics cards that require the 12+4 pin power interface. The 17.7 inch length adds reach between the power supply and the GPU.

Installation check

Verify that your modular power supply provides three native 8-pin PCIe outputs on separate cables before ordering. This adapter must not be plugged directly into the PSU; it extends existing modular leads only. Ensure the 16-pin socket on the graphics card matches the 12+4 pin male connector supplied here.

Thermals and draw

High-density 16AWG tinned copper conductors and a nylon braided jacket are used to handle the current required by 12VHPWR graphics cards. Three included cable combs keep the bundle organised for consistent airflow. The pre-bent, ultra-soft construction reduces strain on both connectors during normal operation.

Questions about this item

Does the 17.7 inch cable ship with the three cable combs shown in the photos?

Yes, the extension includes three cable combs so you can align and secure the sleeved wires for a tidy build.

My PSU has two 8-pin PCIe ports — can I still use this 3x8-pin extension for an RTX 4090?

The extension presents three 8-pin female sockets; you would need three 8-pin male leads from the PSU, so a two-port PSU cannot fill all three connectors.

What does the 16-pin (12+4) male end actually mate with on the graphics card?

It plugs directly into the native 12VHPWR socket on RTX 3090 Ti, 4080 or 4090 cards, extending the existing PSU cables by 17.7 inches.
