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 support for the rear of the graphics card. Constructed from high-end aluminum-magnesium alloy material, it offers strong and lasting support, ensuring durability. The surface undergoes sandblasting and anodizing for a premium texture and long-lasting finish. Thoughtful protection design includes a silicone pad on the top support point to prevent damage to the graphics card. The bottom of the bracket incorporates 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 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 in place.
