USB 3.0 header to USB 2.0 front-panel adapter

This 15 cm cable converts a motherboard USB 3.0 20-pin female header to a standard USB 2.0 9-pin male connector. It lets builders run a case front-panel USB 2.0 port from a newer 20-pin header. Data throughput is limited to 480 Mbps. The short length keeps routing tidy inside compact chassis.

Installation notes and common issues

Plug the 20-pin female end onto the motherboard header and the 9-pin male end into the case front-panel cable. Keyed connectors prevent reversed insertion. The adapter does not add USB 3.0 signalling; connected ports will operate at USB 2.0 speeds only. Ensure the motherboard header pin-out follows the standard 20-pin layout before fitting.

Speed ceiling decides fit

Maximum transfer rate is 480 Mbps, matching USB 2.0 High Speed. Buyers needing 5 Gbps SuperSpeed throughput must connect a native USB 3.0 front-panel cable instead. This adapter is the right part when the case provides only a 9-pin lead and the board offers only a 20-pin header.
