White PCIe 5.0 12VHPWR 16-pin male to dual 8-pin female splitter cord, 13-inch length

SMUGDESK

SMUGDESK PCIe 5.0 12VHPWR 16Pin to 2x8Pin Power Splitter Cord 13Inch White

SKU CH-T69B-97VJV

White PCIe 5.0 12VHPWR 16-pin to dual 8-pin splitter powers RTX 4070 series cards from legacy PSUs

Option Black

  • White jacket matches white-themed builds for clean internal aesthetics
  • PCIe 5.0 12VHPWR 16Pin male plugs directly into RTX 4070 series GPU power port
  • 1-to-2 splitter converts new 16Pin interface to two 8Pin PCIe female ports for older PSU compatibility
  • Thick high-gauge wire core lowers voltage drop and heat under full-load GPU operation
  • 13-inch length allows neat routing without obstructing case fans, CPU coolers and airflow

White PCIe 5.0 12VHPWR Splitter for RTX 4070 Series

This white PCIe 5.0 12VHPWR power splitter cord adapts the 16Pin (12+4) male connector on RTX 4070 series graphics cards to two 8Pin PCIe female ports from an existing modular power supply. It is intended for builders upgrading to Ada Lovelace generation GPUs who want to keep their current PSU. The 13-inch length supports clean routing inside standard chassis layouts. The pure white jacket matches white-themed builds for a unified internal aesthetic.

Solves PSU Compatibility Without Full Upgrade

The 1-to-2 splitter design lets you power a new 12VHPWR graphics card using two standard 8Pin PCIe cables from your legacy modular PSU, avoiding the cost and effort of a complete power supply replacement. Heavy-gauge wire cores reduce voltage drop and heat during sustained high-power draw from gaming or rendering workloads. The all-white exterior replaces standard black cables for a cleaner look in tempered glass cases or RGB-themed systems. It tidies visible wiring while maintaining stable delivery.

Verify PSU 8Pin Ports and Cable Reach Before Buying

Confirm your modular power supply provides two independent 8Pin PCIe GPU rails and that the corresponding cables are long enough to reach the graphics card with 13 inches of additional splitter length. This adapter only works with PSUs that use standard 8Pin PCIe outputs on the unit side; it cannot connect to 6Pin or proprietary ports. Ensure the 16Pin male plug seats fully into the GPU power socket to prevent overheating. Buyers needing native 12VHPWR PSU cables or a different cable length should look elsewhere.

Questions about this item

Will the 16Pin 12VHPWR male plug on this cable need periodic reseating or replacement after extended use?

The 16Pin 12VHPWR male plug is a solid connector rated for PCIe 5.0 power delivery; it does not require scheduled reseating or replacement unless physical damage or connector melting occurs from incorrect insertion.

What is the first limit reached when the RTX 4070 series card draws sustained full load through the 13‑inch splitter?

The cable’s heavy‑gauge wire core is designed to minimise voltage drop and heat, so the practical limit is the 8Pin PCIe rails on your power supply rather than the splitter itself.

How much extra heat or noise does the white 12VHPWR extension add when the GPU runs all day?

The thick high‑gauge conductors keep resistance low, so the cable adds negligible heat and produces no audible noise during continuous operation.
