Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide a support height range of 74–120mm. Height is adjustable to accommodate various chassis specifications, offering effective support for the rear of the graphics card. Constructed from high-end aluminum-magnesium alloy, the bracket delivers strong, durable, and long-lasting stability. The surface undergoes sandblasting and anodization for a refined texture and enhanced durability. The top support point includes a silicone pad to prevent damage to the graphics card. The bottom features a magnet combined with a silicone sheet, enabling secure attachment to ferromagnetic surfaces such as power supply compartments and chassis base plates. Magnetic adhesion is strong and stable, ensuring reliable support. Non-slip rubber pads on both ends aid in easy installation and help prevent movement inside the chassis, reducing the risk of damage. To use the rotating screw: Turn the telescopic screw counterclockwise to reach the desired height, then tighten the middle locking ring clockwise to secure the position.
