Lian Li USB Module O11DE-3XV2 is an internal USB expansion module designed specifically for compatible Lian Li O11DEX and O11DERGB-X chassis. It restores or extends USB connectivity inside the case and connects with the chassis wiring to provide functional front-panel or internal USB ports as designed by Lian Li. The module is intended as a direct replacement or upgrade for the original internal USB board supplied with these chassis models.

Advantages

This internal USB expansion module supports native chassis integration and follows the original layout and connections, ensuring compatibility with the O11DEX and O11DERGB-X series. It provides a compact, factory-style solution without requiring case modification, and allows users to regain or expand USB access for front-panel connectors or internal devices. The module is suitable for straightforward installation and aligns with the chassis’ cable routing and mounting points.

Suitable for

• Replacing a damaged or lost internal USB module in Lian Li O11DEX and O11DERGB-X chassis
• Restoring front-panel USB functionality after internal upgrades or maintenance
• Adding or re-enabling internal USB ports for accessories such as RGB controllers, fan hubs, or internal card readers

Key specifications

• Form factor: internal expansion module tailored to Lian Li O11DEX / O11DERGB-X chassis
• Connectivity type: USB ports compatible with chassis front-panel wiring and motherboard headers
• Mounting: designed to fit existing mounting points inside the compatible chassis
• Cable interface: internal ribbon or header cables as used by the chassis wiring harness
• Compatibility: electrically and mechanically matched to the O11DEX and O11DERGB-X models

How to use

Power down the system and disconnect it from mains before installation. Open the chassis side panel and locate the internal mounting area where the original USB module is installed. Remove any screws or fasteners holding the old module and disconnect its internal cable from the motherboard header. Install the Lian Li USB Module O11DE-3XV2 into the same mounting position, secure it with the original screws or provided fasteners, and reconnect the cable to the appropriate USB header on the motherboard. Close the chassis, reconnect power, and verify that front-panel or internal USB ports are recognized by the operating system.

Recommendations

Handle internal cables and PCB contacts with care to avoid electrostatic discharge. Use the original chassis mounting hardware when possible to ensure correct alignment. If ports are not detected after installation, confirm header orientation and seating, and consult the chassis manual for header pinouts and troubleshooting steps.
