SMUGDESK

SMUGDESK 2 x 8Pin to 12Pin GPU Power Adapter Cable for RTX 3060 3070 3080

SKU CH-1SS6-3D16A

Converts two PCIe 8-pin PSU connectors into the 12-pin power port required by RTX 3060, 3070 and 3080 graphics cards

  • Converts two PCIE 8-pin connectors to 12-pin GPU power for RTX 3060, 3070, 3080 cards
  • Thick-gauge wire cores deliver stable current under heavy gaming and rendering loads
  • Flexible cable body simplifies internal routing and keeps case wiring tidy
  • Direct plug-and-play design needs no drivers or modifications for quick installation
  • Replaces lost or missing original 12-pin adapter for PC builds and GPU upgrades

Adapts dual 8-pin PSU leads to 12-pin GPU

This SMUGDESK adapter converts two standard PCIE 8-pin power connectors from a power supply into the 12-pin proprietary port found on RTX 3060, 3070 and 3080 graphics cards. It is a direct plug-and-play solution for builders replacing a lost original adapter or upgrading a PSU that lacks the native 12-pin cable. High-conductivity wire cores are designed to deliver stable current under heavy gaming or rendering loads.

Requires two genuine 8-pin PCIE cables from the PSU

The adapter only works when each 8-pin end is plugged into a dedicated PCIE output on the power supply; using splitter cables or daisy-chained connectors can cause insufficient power delivery and instability. Cable length is suited for routing inside typical chassis, aiding neat internal wiring. No drivers or software configuration are needed for operation.

Compatibility limited to RTX 3060 3070 3080 series

This adapter is specifically made for the 12-pin power interface used on those RTX models and will not fit graphics cards with different power connectors. Buyers whose GPU uses standard 8-pin or 16-pin sockets cannot use this cable. It serves as a targeted replacement for the original adapter supplied with compatible cards.

Questions about this item

Which adapter version matches my RTX 3070?

This cable converts two PCIE 8‑pin outputs to the single 12‑pin port used by RTX 3060 Ti, 3070 and 3080 cards.

What does the 12‑pin connection deliver in my build?

It supplies the full GPU power draw through one proprietary 12‑pin socket, fed by two separate PSU 8‑pin rails for stable current.

What interface standard does the 12‑pin end follow?

The 12‑pin terminal is the proprietary RTX 30‑series power interface; it caps at the combined rating of the two 8‑pin PSU connectors.
