Black dual 8-pin to 12-pin GPU power adapter cable with moulded locking connectors

SMUGDESK

SMUGDESK Dual 8Pin to 12Pin GPU Power Splitter Cord for RTX 3060 3070 3080

SKU CH-QDHK-8QHYG

Converts two 8-pin PCIe outputs into a 12-pin connector for RTX 3060, 3070 and 3080 graphics cards

  • Converts dual 8-pin PSU outputs to RTX 30-series 12-pin GPU power
  • High-conductivity copper wire maintains stable current for RTX 3060, 3070, 3080
  • Locking molded connectors prevent loose contact under heavy GPU loads
  • Plug-and-play installation with no drivers or modifications required
  • Flat flexible cable body enables tidy routing inside PC chassis

Target Use

This dual 8-pin to 12-pin adapter connects a standard power supply to RTX 3060 Ti, 3070 and 3080 graphics cards that require the proprietary 12-pin connector. It enables GPU upgrades on PSUs lacking native 12-pin outputs.

Power Delivery

High-conductivity copper conductors minimise voltage drop during gaming and overclocking loads. Firm locking moulded connectors maintain tight contact to prevent power interruptions or system crashes under heavy draw.

Compatibility Limit

Built specifically for the RTX 30-series 12-pin interface, this cable does not fit the newer 16-pin 12VHPWR connector. Verify your graphics card power port before purchasing.

Questions about this item

How do I install the dual 8pin to 12pin adapter for my RTX 3080?

Plug each 8pin connector into separate PCIE power channels on the power supply, then attach the 12pin end to the graphics card.

Will the adapter connectors wear out and need replacing?

The precision-molded locking connectors are designed to maintain tight contact and prevent loose connections during high-load operation.

What power limit appears first when running the RTX 3070 under sustained load?

The cable supports high-current transmission with minimal voltage drop, so the limit will be the power supply's PCIE channel rating or the GPU's own power target.
