Black dual 6/8-pin PCIe to mini 12-pin GPU power adapter cable with flexible sleeved wires and compact connectors

SMUGDESK

SMUGDESK Dual PCIe 6/8Pin to Mini 12Pin Power Splitter Cord for RTX 3080 3090

SKU CH-D13Z-HQDDS

Converts two standard PCIe 6/8-pin PSU cables into the mini 12-pin connector required by RTX 3080 and RTX 3090 graphics cards

  • Dual 6/8-pin PSU inputs power RTX 30-series 12-pin GPU
  • High-conductivity copper core maintains stable current under full GPU load
  • Flexible cable body simplifies routing inside compact PC cases
  • Plug-and-play adapter replaces lost or damaged original 12-pin cord
  • Each port accepts 6-pin or 8-pin plug for broad PSU compatibility

Dual 6/8-Pin to Mini 12-Pin Adapter

This SMUGDESK power splitter converts two standard PCIe 6-pin or 8-pin connectors from a modular power supply into the proprietary mini 12-pin male plug required by GeForce RTX 3080 and RTX 3090 graphics cards. It provides a direct replacement when the original GPU power cable is missing or damaged. High-conductivity copper cores maintain stable current delivery under full GPU load.

Build Integration and Cable Routing

The adapter requires two independent PCIe cables from the power supply; daisy-chained connectors must not be used. Its flexible cable body simplifies routing inside compact chassis and reduces clutter compared to stiff factory cables. Each input port accepts either 6-pin or 8-pin plugs, ensuring compatibility with most full-modular and semi-modular PSU designs without additional adapters.

Suitability and Limitations

This cord suits builders installing an RTX 3080 or RTX 3090 into a system whose PSU lacks a native mini 12-pin output but offers two spare PCIe power leads. It is not for users whose power supply provides only a single PCIe cable or who need to power graphics cards using standard 8-pin or 12VHPWR connectors instead of the mini 12-pin interface.

Highlights

  • Dual 6/8-pin PSU inputs power RTX 30-series 12-pin GPU
  • High-conductivity copper core maintains stable current under full GPU load
  • Flexible cable body simplifies routing inside compact PC cases
  • Plug-and-play adapter replaces lost or damaged original 12-pin cord
  • Each port accepts 6-pin or 8-pin plug for broad PSU compatibility

Questions about this item

What happens if I run the adapter on a single PSU cable instead of two independent ones?

Using a daisy-chain cable can cause voltage drop, connector overheating and unstable power delivery to the RTX 3080 or RTX 3090 under full load.

Does the cable itself generate noticeable heat during all-day gaming or rendering?

The high-conductivity copper core is designed to minimise resistance, so the adapter stays cool while delivering stable current to the mini 12-pin port.

Which power-supply cables must I already have to use this adapter?

You need two separate PCIe 6-pin or 8-pin leads from a modular or semi-modular PSU; a single daisy-chain lead will not work.
