Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide adjustable support ranging from 74mm to 120mm. This adjustable height accommodates 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 anodizing treatment 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 metal surfaces such as the power supply compartment or chassis base plate. This magnetic design ensures stable and reliable support. Non-slip rubber pads on both ends enhance stability during installation and help prevent movement inside the chassis. To use the rotating screw: Turn the telescopic screw counterclockwise to reach the desired height, then rotate the middle locking ring clockwise to secure and lock the position.
