12VHPWR 16-pin female to dual PCIe 8-pin male power splitter cord, 6.8in length

SMUGDESK

SMUGDESK 12VHPWR 16Pin Female to Dual PCIe 8Pin Male Power Splitter Cord 6.8IN 17CM

SKU CH-X9EA-ZCJM2

Converts a 12VHPWR GPU port to dual PCIe 8-pin PSU connectors, 17 cm length for tidy internal routing

  • 12VHPWR 16-pin female powers RTX 40 GPUs from dual 8-pin PSU cables
  • 8 in length keeps chassis wiring tidy and airflow clear
  • Dual PCIe 8-pin (6+2) male ends fit standard PSU power ports
  • Precision-molded connectors maintain tight contact under heavy GPU load
  • Quality conductors reduce resistance for stable delivery during gaming and rendering

GPU Power Adapter

This SMUGDESK splitter converts a single 12VHPWR 16-pin female socket into two PCIe 8-pin (6+2) male plugs so a compatible graphics card can draw power from a standard power supply. The 6.8 inch (17 cm) length keeps internal wiring short and tidy for clean cable management.

Gaming and Workstation Builders

Builders installing an RTX 40 series card on a PSU that only has PCIe 8-pin outputs will find this cord fits the requirement. Systems already equipped with a native 12VHPWR connector or units lacking dual PCIe 8-pin cables should use a different connection method.

Connector Specification

The cable provides a 16-pin (12+4) female end for the GPU and splits to dual 8-pin (6+2) male ends for the PSU, matching the 12VHPWR interface used by RTX 40 series graphics cards.

Highlights

  • 12VHPWR 16-pin female powers RTX 40 GPUs from dual 8-pin PSU cables
  • 8 in length keeps chassis wiring tidy and airflow clear
  • Dual PCIe 8-pin (6+2) male ends fit standard PSU power ports
  • Precision-molded connectors maintain tight contact under heavy GPU load
  • Quality conductors reduce resistance for stable delivery during gaming and rendering

Questions about this item

Should I use one or both 8-pin plugs for my RTX 40 card?

Use both PCIe 8-pin connectors from the power supply; the splitter is built to combine them into the single 12VHPWR 16-pin GPU socket.

What does the 16-pin connector actually do for an RTX 40 GPU?

It delivers the 12 V power rails and the four sense pins that the graphics card expects, replacing the older 8-pin arrangement.

Will the 12VHPWR interface work with my existing PSU’s 8-pin ports?

Yes, the dual 8-pin (6+2) male ends plug into any standard PCIe power ports on the supply, while the 16-pin female end mates with the GPU.
