Provides stable reinforcement to prevent GPU sag and reduce stress on the PCIe slot, helping to extend the life of graphics cards and related components. Designed for desktop PC setups, with particular relevance for supporting and protecting performance graphics cards during heavy workloads or gaming. Adjustable height options of 27 mm, 49 mm, and 74 mm allow compatibility with a wide range of PC cases and GPU clearances. Targeted at computer hardware enthusiasts, builders, and gamers, offering improved system stability and reliability without adding unnecessary complexity. Height options: 27/49/74 mm to fit different case sizes and GPU heights; compatibility with standard desktop builds. Performance focus: reduces GPU sag under load, supporting longterm PCIe connector integrity and card stability. Use scenarios Scenario 1: end singleGPU desktop build in a mid to fulltower case where card sag risk is present; select the appropriate 49 mm or 74 mm height to align the GPU with the PCIe slot and maintain stable operation during gaming or rendering. Scenario 2: Compact or small form factor builds (such as minitower or compact cases) with tall GPUs; use the 27 mm height to fit within limited clearance while providing essential support to the graphics card. Scenario 3: Enthusiast or overclocked systems with heavy GPU workloads; the adjustable heights help maintain card alignment and reduce mechanical stress during extended sessions.
