Verdict

The KFA2 GeForce RTX 4080 Super SG 1-Click OC is a high-end graphics card built on the NVIDIA Ada Lovelace architecture, featuring 10,240 CUDA cores and 16GB of 256-bit GDDR6X memory with a 736 GB/sec bandwidth. It offers a factory-overclocked boost clock of 2610 MHz, which can be further increased to 2625 MHz via its signature 1-Click OC software. This 3.5-slot card is characterized by its robust Serious Gaming (SG) cooling system, which includes three 102mm fans and an optional 1-Clip Booster 2.0 fourth fan for enhanced airflow. Main pros include exceptional 4K gaming performance with DLSS 3 support, efficient thermal management through its massive heatsink, and a bundled ARGB support bracket to prevent GPU sag. However, available cons include its massive physical footprint that may require a large chassis and potential noise levels that can become noticeable under heavy loads.
