GPU bracket Lian Li O11DE-9X Full Tower Steel 1mm

The Lian Li O11DE-9X upright GPU bracket allows large 40-series graphics cards to be mounted in an upright position inside full-tower cases, improving cooling by creating a chimney-style airflow and enabling intake fans behind the GPU. Made of durable steel and designed for compatibility with side fan brackets, this bracket supports heavy and oversized cards while keeping installation straightforward.

Advantages

The bracket is optimized for direct cooling by positioning the GPU upright next to the motherboard, which encourages vertical airflow and lets users mount intake fans behind the card for better temperature control. It installs directly to the side fan bracket to simplify fitting and slightly shifts the GPU position to avoid interference with top or bottom fans and radiators. The adjustable steel construction supports a wide variety of GPU sizes up to 3 slots thick.

Suitable for

• Full-tower PC builds requiring upright GPU mounting
• Systems using 40-series or large, heavy graphics cards
• Builds where improved GPU airflow and intake fan placement are desired

Key specifications

• Compatible with GPUs up to 3 slots thick
• Maximum supported length: ≤ 348 mm
• Supported width range: 135–150 mm
• Maximum supported thickness: ≤ 75 mm
• Designed for installation on side fan bracket of compatible cases
• Manufacturer: Lian Li, MPN: O11DE-9X, EAN: 4718466013118

How to use

Install the upright GPU bracket by mounting it directly to the side fan bracket of a compatible full-tower case. Position the GPU in the bracket so it stands upright beside the motherboard, then secure the card according to the bracket’s adjustable fittings and the case’s mounting points. If needed, adjust the bracket to accommodate the card’s length, width and thickness and ensure there is no contact with top or bottom fans or radiators.

Recommendations

Verify that your case supports side fan bracket mounting and that the GPU dimensions fall within the specified limits (length ≤ 348 mm, width 135–150 mm, thickness ≤ 75 mm). For optimal thermal performance, pair the upright GPU bracket with intake fans behind the GPU and check clearances before finalizing installation.
