2. Setup and Installation
2.1 Compatibility Check
- Ensure your GPU uses three 8-pin PCIe power connectors. This cable is designed for GPUs requiring 3x8-pin power.
- This cable is compatible with NVIDIA GeForce RTX 50 and 40 Series graphics cards that utilize 12V-2X6 connectors, provided they are adapted to 3x8-pin.
- An L-Wireless Controller is required for RGB lighting and fan control. This controller is not included with the PW12-1W model.
2.2 Physical Installation
- Connect to GPU: Carefully connect the three 8-pin connectors of the Strimer Wireless cable to the corresponding 8-pin power inputs on your graphics card. Ensure a secure fit.
- Connect to Power Supply: Connect the other end of the Strimer Wireless cable to your power supply's PCIe power outputs.
- Connect L-Wireless Controller (Sold Separately): If you have an L-Wireless Controller, connect it to an available USB Type-A port on your motherboard or PC case. The controller communicates wirelessly with the Strimer cable for RGB effects.
- Cable Management: Utilize the provided clips to manage the cable and light guides for a clean aesthetic. The light strips extend to the sides, offering enhanced visual appeal.
