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

Upright GPU Bracket for 40 Series GPU — an add-on bracket designed to mount large 40-series graphics cards in an upright position inside compatible full-tower cases. Made to work as an upgrade kit for owners of earlier upright brackets (models O11DE-2 / O11DE-6) and to fit GPUs up to three slots thick, this steel bracket improves direct airflow around the card and accommodates longer, thicker 40-series cards without obstructing other cooling components.

Advantages

The bracket is optimized for direct cooling by positioning the GPU upright next to the motherboard, creating a chimney-style airflow and enabling intake fans to be mounted behind the GPU for better temperature control. Installation is simplified by mounting the kit directly to the side fan bracket, which slightly shifts the GPU position to avoid interference with top or bottom fans and radiators. The adjustable design supports a wide range of GPU sizes within defined length, width and thickness limits.

Suitable for

• Upgrading an existing Lian Li upright GPU bracket (O11DE-2 / O11DE-6) to support 40-series GPUs
• Full tower systems where upright GPU mounting is desired for improved airflow
• Builds with large, heavy GPUs that require additional structural support

Key specifications

• Compatibility: designed for 40-series GPUs and owners of original upright bracket models O11DE-2 / O11DE-6
• Maximum supported length: ≤ 348 mm
• Supported width: 135 mm – 150 mm
• Maximum supported thickness: ≤ 75 mm (up to 3 slots)
• Material context: intended as an upgrade kit compatible with Lian Li full tower configurations (see product family O11DE-9X / O11DE-9W)

How to use

Install the upright GPU kit by attaching it to the case side fan bracket according to the case’s mounting points. Position the GPU in the upright bracket, adjust the bracket to match the GPU length, width and thickness, and secure the card. If replacing or upgrading from O11DE-2 / O11DE-6, follow the supplemental kit instructions to ensure correct alignment and clearance relative to top and bottom-mounted fans or radiators.

Recommendations

Verify your GPU dimensions against the supported limits (length ≤ 348 mm, width 135–150 mm, thickness ≤ 75 mm) before purchase. Ensure adequate case airflow and confirm compatibility with your specific Lian Li case model when using the bracket as an upgrade.
