Gray 16-pin to three 8-pin sleeved power extension cable with combs, 17.7 inches

FormulaMod

FormulaMod RTX 3090 4090 4080 16Pin to 3x8Pin PCIe 5.0 Sleeved Extension Cable 17.7 inch Gray

SKU CH-PZ4N-XE2YA

Extends a 16-pin PCIe 5.0 GPU connector to three 8-pin power plugs for RTX 3090, 4080 and 4090 cards, using 17.7-inch sleeved 16 AWG copper wire with cable combs for tidy routing

Color Gray

  • 16-pin 12VHPWR male connector links to three 8-pin female plugs for RTX 3090 4080 4090 GPUs
  • 7-inch extension lets existing dual 8-pin PSU cables reach the graphics card without a new power supply
  • PCIe 5.0 rated 16AWG tinned copper conductors carry the required current with low resistance
  • High-density nylon braided jacket and pre-bent ultra-soft design resist daily wear and simplify routing
  • Three included cable combs align the sleeved wires for tidy management and a unified look

PCIe 5.0 16-pin extension

This 16-pin male to three 8-pin female extension cable connects RTX 3090 4080 4090 graphics cards to existing power supplies. The 17.7 inch length adds reach without replacing the PSU. High-density 16AWG tinned copper conductors carry the load through a durable nylon braided jacket.

Thermals noise and power

The cable is a passive conductor so it generates no noise and adds no measurable heat to the system. Power delivery depends entirely on the host power supply and the GPU demand; the extension itself does not alter draw. The pre-bent ultra-soft design reduces strain on connectors during routing.

Cable combs and routing

Three included combs align the individual wires for a uniform appearance inside the case. They snap on after the cable is positioned and can be slid to any point along the braid. This lets builders achieve clean parallel runs without zip ties or tape.

Questions about this item

How do I install the 16-pin to 3x8-pin extension cable without damaging the 12VHPWR connector?

Connect the existing dual 8-pin modular cables from the power supply to the three 8-pin female ends first, then plug the 16-pin male end into the GPU; never insert the extension directly into the PSU.

What maintenance will the 16AWG tinned copper wire and nylon braided jacket need over time?

Inspect the braid and connectors periodically for fraying or discoloration, reseat the 16-pin and 8-pin plugs if they feel loose, and keep the included cable combs tight to prevent stress on the wires.

At what point does the 17.7-inch length become a limitation under sustained load?

The fixed 17.7-inch reach can restrict routing in large cases or behind vertical GPU mounts, forcing sharp bends that increase resistance and heat on the 16AWG conductors during prolonged heavy draw.
