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

SKU CH-GZN8-25GD3

Extends a 16-pin PCIe 5.0 GPU connector to three 8-pin cables, 17.7 inches long with braided sleeving and cable combs

Color Green+White

  • Extends GPU power reach with 17.7-inch 16-pin to triple 8-pin layout
  • Supports RTX 3090, 4080 and 4090 cards through PCIe 5.0 12VHPWR male connector
  • High-density 16AWG tinned copper cores deliver stable current over the full length
  • Pre-bent ultra-soft nylon braid resists kinks and daily wear inside the case
  • Three included cable combs keep the three branches aligned for tidy routing

Extension Cable for 16-Pin GPUs

This FormulaMod extension cable converts a 16-pin 12VHPWR male connector into three 8-pin female PCIe connectors. It measures 17.7 inches and uses 16AWG tinned copper wire wrapped in a durable nylon braided jacket. The cable is rated for PCIe 5.0 and includes three cable combs for tidy routing. It is designed to extend the reach of existing modular PSU cables without replacing the power supply.

Suited for RTX 3090 Ti and RTX 4090 builds

This cable suits builders installing an RTX 3090 Ti, RTX 4090 or RTX 4080 who need to connect the card to a power supply that only provides 8-pin PCIe modular cables. It is not for users whose PSU already has a native 12VHPWR or 12+4 pin output. Buyers who want a direct PSU-to-GPU cable without an extension should look at a different product type.

Check PSU modular cables

Verify that your power supply includes enough 8-pin PCIe modular cables to occupy all three female connectors on this extension. Confirm the 17.7-inch length fits your case routing path and that the pre-bent, braided cable can bend to your required radius. Remember this is an extension only; it must plug into the PSU’s own modular cables, not directly into the PSU.

Questions about this item

What existing PSU cables do I need to connect this 16-pin extension to my power supply?

You need three 8-pin PCIe modular cables from your PSU to plug into the female ends of this extension.

Will this extension work if I keep my current dual 8-pin GPU power cables?

Yes, it is designed to connect your existing dual 8-pin modular cables to a 16-pin graphics card.

How can I verify the extension is seated correctly after installation?

Ensure each 8-pin connector clicks firmly into the PSU cables and the 16-pin plug locks securely into the graphics card.
