K420 128-bit DDR3 graphics card

The K420 is a PCIe graphics card with 2 GB of DDR3 memory on a 128-bit bus. It provides DisplayPort and DVI outputs for professional graphics, Photoshop and CAD design workflows. The card targets users who need basic GPU acceleration for 2D and entry-level 3D applications. It is not suited for modern gaming, heavy compute workloads or multi-monitor 4K setups.

Installation and common issues

The card installs into a standard PCIe slot and draws power from the slot itself, so no extra cables are required. Driver installation is straightforward on current Windows and Linux distributions. Common problems include outdated drivers causing display artefacts and insufficient case airflow leading to thermal throttling under sustained load.
