Sky-blue braided 12VHPWR male to four 8-pin female extension cable 17.7in with three combs

FormulaMod

FormulaMod 16AWG 12VHPWR to 4x8Pin PCIe 5.0 Extension Cable 17.7in Sky-blue

SKU CH-3PDA-CXBVC

Extends 12VHPWR power to four 8-pin PCIe 5.0 connectors using 16AWG copper and includes three cable combs for tidy routing

Color Sky-blue

  • 12VHPWR male to four 8-pin female connectors for RTX 4090 4080 4070 compatibility
  • 16AWG tinned copper wire delivers stable power through 17.7-inch extension length
  • Three included cable combs enable clean routing and unified cable management
  • Pre-bent ultra-soft design with nylon braid resists daily wear and tear
  • Extends existing dual 8-pin modular cables so no PSU replacement is needed

Connection Layout

This 12VHPWR male to four 8-pin female extension cable connects an RTX 4090, 4080 or 4070 graphics card to an existing dual 8-pin modular power supply output. It is built for PCIe 5.0 power delivery and adds 17.7 inches of reach without replacing the PSU. The 16AWG tinned copper conductors handle the current required by 3090 and 40-series cards.

Sustained Load Behaviour

High-quality 16AWG tinned copper wire maintains stable voltage delivery during extended gaming or compute sessions. The extension design simply lengthens the existing power path, so the PSU’s own regulation and protection circuits remain in full control. No active components are added, meaning the cable does not introduce additional points of failure under continuous draw.

Thermals Noise and Power

Passive construction produces no fan noise and adds negligible resistance, so waste heat stays minimal inside the case. The ultra-soft pre-bent nylon braid routes cleanly around tight corners, improving airflow compared to stiff stock cables. Three included cable combs keep the four 8-pin branches aligned, reducing clutter that can trap warm air near the GPU.

Questions about this item

Does the 16AWG cable run hot or draw extra power when the GPU is under load all day?

The 16AWG tinned copper conductors are rated for the 12VHPWR specification and add no measurable heat or power draw during sustained operation.

What existing cables must my power supply already provide for this extension to work?

Your modular PSU must supply four 8-pin (7+1) PCIe cables that plug into the female ends of this extension.

Will this 12VHPWR extension work with my older RTX 3090 that uses standard 8-pin connectors?

No — the male 16-pin (12+4) connector only fits RTX 4090, 4080 or 4070 class cards with a native 12VHPWR socket.
