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 rear support for the graphics card. Constructed from high-quality aluminum-magnesium alloy, the bracket delivers strong, durable, and long-lasting performance. The surface undergoes sandblasting and anodization for a refined texture and enhanced durability. The support point features a silicone pad to prevent scratching or damaging the graphics card. The bottom includes 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 stable and reliable, providing firm support. Non-slip rubber pads on both ends aid in easy installation and ensure stability within the chassis, helping to prevent movement or contact that could damage the card. To use the rotating screw: Turn the telescopic screw counterclockwise to achieve the desired height, then rotate the middle locking ring clockwise to secure and lock the position.
