Telescopic helical design. The graphics card bracket features a telescopic screw mechanism, allowing the GX-30 Plus to provide adjustable support with a height range of 74–120mm. This enables flexible adaptation to various chassis specifications, offering effective rear support for the graphics card. High-quality aluminum-magnesium alloy construction. The magnesium-aluminum alloy material ensures strong, durable support. The surface undergoes sandblasting and anodization for a refined texture and long-lasting finish. Enhanced support and protection. The top contact point is lined with a silicone pad to prevent damage to the graphics card. The bottom of the bracket includes a magnet combined with a silicone sheet, allowing secure attachment to metal surfaces such as the power supply compartment or chassis base plate for stable support. Safe and reliable magnetic attachment. Non-slip rubber pads are located at both ends for stability and to prevent scratching or shifting inside the chassis. The magnetic base securely adheres to ferromagnetic materials, ensuring firm placement and dependable support. Instructions for adjusting 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.
