2. Safety Information
- Ensure your computer is powered off and unplugged from the wall outlet before beginning installation.
- Discharge any static electricity from your body by touching a grounded metal object before handling components.
- Handle all components with care to prevent damage.
- Refer to your PC case and GPU manuals for additional safety guidelines.
- This kit is designed for PCI-E 3.0 compatibility only. Using it with PCI-E 4.0 graphics cards may result in instability or malfunction.
3. Setup and Installation
3.1 Preparation
- Power off your computer and disconnect all cables.
- Open your PC case to access the interior.
- Remove your existing graphics card if one is installed.
- Identify the PCI-E x16 slot on your motherboard where the riser cable will connect.
3.2 Installation Steps
- Remove PCI Slot Covers: Remove the necessary PCI slot covers from the rear of your PC case to accommodate the vertical GPU bracket. For the Lian Li O11 Dynamic series, this typically involves removing all horizontal PCI slot covers.

- Connect the Riser Cable: Attach the PCI-E x16 3.0 riser cable to the vertical GPU bracket. Ensure the cable is routed neatly and does not obstruct airflow or other components. Connect the other end of the riser cable to the primary PCI-E x16 slot on your motherboard.

- Final Checks: Double-check all connections. Close your PC case and reconnect all external cables.
4. Operating Instructions
Once the vertical GPU bracket and graphics card are installed, power on your computer. The system should recognize the graphics card as usual. No special software or drivers are required for the bracket itself, as it functions as a passive extension. Ensure your graphics card drivers are up to date for optimal performance.
5. Maintenance
- Periodically inspect the riser cable and bracket for any signs of wear or damage.
- Ensure all screws remain tight to prevent GPU sag.
- Keep the interior of your PC case clean from dust to maintain optimal airflow and component temperatures.
- Avoid bending the riser cable excessively, as this can damage the internal wiring.
6. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Graphics card not detected | Riser cable not fully seated; BIOS/UEFI settings; PCI-E 4.0 card with PCI-E 3.0 riser. | Ensure riser cable is firmly connected to both motherboard and GPU. Check motherboard BIOS/UEFI for PCI-E slot settings (set to Gen3 if applicable). Verify GPU is PCI-E 3.0 compatible. |
| System instability or crashes | Loose connections; incompatible PCI-E version; faulty riser cable. | Re-seat all connections. Confirm PCI-E 3.0 compatibility. Test the graphics card directly in the motherboard slot to rule out riser cable issues. |
| GPU sag | Insufficiently secured bracket or GPU. | Ensure all mounting screws for the bracket and GPU are tightened. Consider additional GPU support if necessary. |
