4 Inch USB 3.0 20-Pin Motherboard Header Female to USB 2.0 8-Pin Male Internal Adapter Cable

This 4-inch internal adapter cable converts a motherboard USB 3.0 20-pin female header to a USB 2.0 8-pin male connector, solving compatibility issues between old USB 2.0 front panels and newer motherboards equipped with only USB3.0 20pin headers. The short 4-inch length keeps internal wiring tidy and avoids messy cable clutter inside computer cases. Constructed with high-conductivity copper wiring and precision molded plastic connectors, it delivers steady USB 2.0 data and power signals without lag or connection failure. The flexible flat wire can be neatly routed alongside other internal hardware without blocking airflow. It supports plug-and-play operation without any extra drivers, ideal for DIY PC assembly, case replacement and front USB port retrofit. Each cable undergoes strict connectivity testing to ensure long-term stable daily use for desktop computers.
