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

SKU CH-M68P-BEMCF

Converts two PCIe 8‑pin outputs into a single 12‑pin connector for RTX 3060, 3070 and 3080 graphics cards using 18 AWG tinned copper wire with locking latches

  • Powers RTX 30-series GPUs from existing PSU via dual 8-pin PCIe connectors
  • 18AWG tinned copper wire maintains stable high-current delivery under heavy load
  • Latch-lock connectors click securely to prevent accidental power loss from vibration
  • Flexible flat cable enables tidy internal routing for improved airflow
  • Direct-fit adapter upgrades older power supplies lacking native 12-pin port

Dual 8Pin to 12Pin GPU Adapter

This adapter converts two standard PCIe 8-pin power outputs into a single 12-pin connector for NVIDIA RTX 3060, 3070 and 3080 graphics cards. It lets builders use an existing power supply that lacks a native 12-pin port. The cable targets anyone upgrading to an Ampere-generation GPU without replacing their PSU.

18AWG Tinned Copper With Latch Connectors

Each conductor uses 18AWG tinned copper to reduce voltage drop and heat under heavy gaming or rendering loads. Locking latches on both the 8-pin and 12-pin ends click securely to prevent accidental disconnection from vibration. The flexible flat cable body simplifies routing and keeps the interior tidy for better airflow.

Requires Two Independent PSU 8Pin Rails

The adapter must be fed by two separate PCIe 8-pin cables from the power supply; daisy-chaining from a single cable is unsafe. Your PSU must meet the GPU’s total power specification, which this cable does not define. Builders with only one PCIe output or insufficient PSU capacity cannot use this adapter.

Questions about this item

What does the 12-pin connector on this adapter support?

The mini 12-pin male end plugs directly into the power port on RTX 3060, 3070 and 3080 graphics cards, converting two standard PCIe 8-pin outputs from your PSU into the single 12-pin input those GPUs require.

What clearance does the flat cable body need inside the case?

The flexible flat cable body is designed for tidy internal routing and easy cable management inside a gaming PC chassis, allowing neat wiring arrangement that helps improve airflow and keep the internal build clean.

How do I connect the two 8-pin plugs to the PSU correctly?

Connect two separate PCIe 8-pin power cables from independent PSU rails to the adapter; do not daisy-chain both 8-pin plugs from a single PCIe cable, then insert the 12-pin male end into the graphics card power port until the latch clicks.
