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, the bracket delivers strong, lasting support and is both sturdy and durable. The surface undergoes sandblasting and anodization for a refined texture and long-lasting finish. Thoughtful protection design includes a silicone gasket on the top support point to prevent damage to the graphics card. The bottom of the bracket incorporates a magnet and silicone sheet, enabling secure attachment to metal surfaces such as the power supply compartment or chassis base plate for stable, reliable support. Safety protection with stable magnetic suction. Non-slip rubber pads are located at both ends, ensuring stability during installation and preventing movement inside the chassis. The magnetic base securely attaches to iron-based materials like the power supply housing or chassis floor, offering firm adhesion and dependable support. Instructions for use: Rotate the telescopic screw counterclockwise to reach the desired height, then turn the middle locking ring clockwise to secure and lock the position.
