USB 3.0 20-pin to USB 2.0 9-pin adapter

This adapter cable connects a USB 2.0 9-pin header device to a USB 3.0 20-pin motherboard header. It converts the physical interface so older front-panel or drive-bay devices can be used on newer boards. The cable is four inches long and coloured black. Data transfer operates at up to 480 Mbps under the USB 2.0 specification.

Suits builders adding legacy front-panel ports

The adapter is intended for installations where a case or accessory provides only a 9-pin USB 2.0 connector. It does not increase the signalling rate beyond USB 2.0 speeds. Builders who need full USB 3.0 throughput for their front-panel ports should look for a native 20-pin header or a different solution.

Simple internal connection with no drivers required

Installation consists of plugging the 20-pin female end onto the motherboard header and the 9-pin male end into the device cable. The short four-inch length limits routing options in larger cases. Ensure the keyed connectors are aligned before applying force to avoid bent pins.
