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 freely adjustable to accommodate various chassis specifications, offering effective rear support for the graphics card. Constructed from high-end aluminum alloy, the bracket delivers strong, lasting support and is both sturdy and durable. The surface undergoes sandblasting and anodizing for a refined texture and long-lasting finish. The top support point includes a silicone pad to prevent damage to the graphics card. The bottom of the bracket features a magnet combined with a silicone sheet, enabling secure attachment to ferromagnetic surfaces such as the power supply compartment or chassis base plate for stable support. Non-slip rubber pads on both ends ensure stability and prevent slipping during installation, helping to protect the graphics card from impact. To use the rotating screw, turn the telescopic screw counterclockwise to the desired height, then tighten the middle locking ring clockwise to secure the position.
