Silverstone (SST-CP09) External to Internal 19 Pin USB 3.0 Adapter Cable
For users with cases that only support external USB 3.0 (Type A) connectors, the SilverStone CP09 adapter cable is a must have when upgrading to motherboards with internal 19pin USB 3.0 header. It converts two external USB 3.0 type A connectors via a pair of flexible cables to a single 19pin connector for connecting to internal USB 3.0 headers.
