Black and white braided 16-pin to four 8-pin PCIe 5.0 extension cable with combs

FormulaMod

FormulaMod 16AWG 12VHPWR 16Pin to 4x8Pin PCIe 5.0 Extension Cable 17.7in Black+White

SKU CH-XV8E-Z7HBE

Extends a 12VHPWR GPU connection to four 8-pin PCIe 5.0 plugs using 16AWG tinned copper wire, 17.7 inches long with three cable combs for clean routing

Color Black+White

  • Extends GPU power reach with a 17.7 inch 16AWG cable
  • Connects 12VHPWR male to four 8-pin female for RTX 4090 4080 4070TI 3090Ti compatibility
  • Three cable combs included for clean routing and unified look
  • High-density tinned copper with nylon braid ensures durable daily use
  • Pre-bent ultra-soft design simplifies install and adds flexible length

Purpose and Audience

This 12VHPWR extension cable bridges a 16-pin PCIe 5.0 graphics card connector to four 8-pin female plugs, letting owners of RTX 4090, 4080 or 4070 Ti cards reuse existing modular PSU cables. It is built for builders who want a clean, black-and-white sleeved look without replacing their power supply. The 17.7-inch length and included combs suit mid-tower and larger cases where the stock GPU lead falls short.

Build Integration

The male 16-pin end plugs into the GPU while each 8-pin female accepts a standard PCIe modular cable from the power supply, so no new PSU is required. Three supplied combs align the four runs into a single tidy bundle, freeing routing space behind the motherboard tray. Because it is an extension only, the unit must not be connected directly to the PSU; follow the GPU maker’s power guidelines for safe operation.

Thermals Noise and Power

High-quality 16 AWG tinned copper conductors carry the 12 V load with minimal resistance, keeping voltage drop low under typical gaming loads. The ultra-soft nylon braid and pre-bent design reduce strain on the GPU socket, helping maintain stable contact over time. As a passive cable assembly it adds no fan noise or active heat, and its power draw is limited to the transmission losses inherent in the copper run.

Questions about this item

How does the 16AWG wire handle sustained load on a 12VHPWR connection?

The 16AWG tinned copper conductors are rated for the current a 12VHPWR plug delivers, so the cable stays within its thermal limits during continuous GPU operation.

Does the nylon braid trap heat or add noise when the system runs all day?

The high-density nylon braid is passive insulation; it does not generate noise and does not restrict airflow enough to raise temperatures under normal case ventilation.

What existing PSU cables are required to use this extension?

You need a modular power supply with four 8-pin (7+1) PCIe cables to plug into the female ends of this extension.
