Some of our recent enclosure reviews (SilverStone TJ08-E, Fractal Design Define Mini have featured external USB 3.0 ports requiring a connection to a 19-pin header required by the USB 3.0 specification which poses a problem for most motherboards to date. While SilverStone was kind enough to provide an internal USB 3.0 to USB 2.0 adapter with the TJ08-E, it would be ideal to take advantage of the USB 3.0 capability. Enter SilverStone’s EC01 PCI Express card providing a 19-pin internal connector capable of supporting two USB 3.0 ports.
