PCIe power adapter INTER-TECH GPU-02 12‑pin to 3×8‑pin (34 cm cable)

INTER-TECH GPU-02 is a PCIe power adapter that converts a single 12‑pin GPU connector into three 8‑pin (6+2) PCIe power plugs via a 34 cm cable. The adapter enables flexible cable routing inside a PC chassis and provides additional PCIe connectors when the power supply unit (PSU) lacks the required number of native 8‑pin outputs. It is designed for use with modern high-power graphics cards and multiple PCIe devices that accept standard 8‑pin (6+2) PCIe power inputs.

Advantages

The adapter provides a compact and straightforward solution for expanding PCIe power connectivity without modifying the PSU. A 34 cm cable offers reach for tidy cable management and improved airflow. Each of the three 8‑pin outputs is in 6+2 configuration, preserving compatibility with both 6‑pin and 8‑pin GPU power inlets. The straightforward single 12‑pin to triple 8‑pin layout minimizes additional connectors inside the case and keeps connections consolidated.

Suitable for

• Adding extra PCIe power connectors for one or more graphics cards
• Systems where the PSU has a limited number of 8‑pin PCIe outputs
• Compact builds that require flexible cable routing for cable management and airflow
• Upgrading or testing GPUs that use standard 8‑pin (6+2) power plugs

Key specifications

• Cable length: 34 cm for flexible internal routing
• Input connector: single 12‑pin GPU-style power plug
• Output connectors: three 8‑pin (6+2) PCIe-compatible plugs
• Connector configuration: 6+2 pins on each PCIe output for 6‑pin or 8‑pin compatibility
• Intended use: powering PCIe devices and GPUs requiring 8‑pin power input

How to use

Connect the single 12‑pin input plug to the corresponding 12‑pin GPU power lead from the power supply or GPU power source, ensuring correct orientation and a secure fit. Route the 34 cm cable inside the case to reach the target devices, then attach the required 8‑pin (6+2) PCIe plugs to the graphics card(s) or PCIe devices. Verify all connections are fully seated and that cable routing does not interfere with fans or moving parts. Power on the system and monitor for stable operation and normal GPU power behavior.

Recommendations

Use the adapter only with compatible PSUs and GPUs that accept standard PCIe 8‑pin (6+2) connectors. Do not exceed the power delivery specifications of the source connector or the PSU. Maintain clear airflow and avoid placing undue strain on connectors; secure loose cables to prevent disconnection or interference with cooling components.
