Sky-blue and white braided 16-pin to three 8-pin PCIe 5.0 extension cable 17.7in with combs

FormulaMod

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

SKU CH-1WD4-W0GVR

Extends a 16-pin 12VHPWR GPU connector to three 8-pin PCIe 5.0 plugs with 17.7-inch sleeved cables and combs for tidy routing

Color Sky-blue+White

  • 16-pin male to three 8-pin female connectors for RTX 3090/4080/4090
  • 7 inch extension adds routing space without replacing the PSU
  • 16 AWG tinned copper wire delivers stable PCIe 5.0 power
  • Nylon-braided jacket with pre-bent design resists daily wear
  • Three included cable combs keep wires aligned for clean management

FormulaMod 16-Pin PCIe 5.0 Extension Cable

This FormulaMod extension cable bridges a 16-pin (12+4) GPU connector to three 8-pin (7+1) PSU cables. It is built for RTX 3090 Ti, 4080 and 4090 graphics cards that require the 12VHPWR interface. The 17.7-inch length adds reach inside larger cases while the pre-bent design and included combs keep routing tidy. High-density 16AWG tinned copper under a nylon braid handles sustained loads.

Replaces short stock 12VHPWR cables

Use this when your power supply lacks a native 16-pin output or when the factory cable is too short for a clean run behind the motherboard tray. The jump is worth it if you want to keep an existing modular PSU and avoid an adapter that plugs directly into the unit. The three 8-pin female ends connect to standard PCIe modular cables for a secure, extension-only link.

Check PSU modular ports

Verify your power supply provides three independent 8-pin (7+1) PCIe outputs on modular headers. Confirm the 17.7-inch length reaches from those headers to the GPU socket without tension or sharp bends. Ensure the case has enough clearance behind the motherboard tray for the combs and braided sleeves. This is an extension only; do not plug it directly into the PSU.

Questions about this item

What connector spacing do the three included cable combs accommodate?

The three combs are designed to align the three 8-pin (7+1) female branches and the single 16-pin (12+4) male plug on the 17.7-inch sleeved extension.

Which side of the 16-pin (12+4) male plug faces the GPU when routing the cable behind the motherboard tray?

The pre-bent orientation positions the latch toward the graphics card so the 12VHPWR connector seats fully without twisting the nylon braid.

When should the 16AWG tinned copper conductors be inspected for discoloration or stiffness?

Check the conductors during any GPU swap or after 12 months of continuous use; replace the extension if the braid shows heat-related darkening or the wires feel brittle.
