Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to support a height range of 74–120mm. Height can be freely adjusted to accommodate various chassis specifications, providing effective rear support for graphics cards. Made from high-quality aluminum alloy, the bracket offers strong, lasting support and is both sturdy and durable. The surface is sandblasted and anodized for a premium texture and long-lasting finish. The top support surface includes a silicone pad to prevent damage to the graphics card. The bottom of the bracket incorporates a magnet and silicone base, enabling secure attachment to ferromagnetic surfaces such as power supply compartments and chassis plates. This ensures stable, firm support with strong magnetic adhesion. Non-slip rubber pads on both ends enhance stability during installation, helping to prevent movement and protect the graphics card. To adjust the height, rotate the telescopic screw counterclockwise to the desired position, then tighten the middle locking ring clockwise to secure it in place.
