SilverStone EC04-P USB 3.0

The high-quality SilverStone EC04-P PCI-Express Card makes it easy to expand your desktop with up to four high-speed USB 3.0 ports. Two ports are connected to the plug and the remaining two ports are in the form of an internal 19pin USB 3.0 connector integrated into the controller board. When connected via a PCI-Express slot version 2.0, you can theoretically reach up to ten times the transfer rate compared to USB 2.0. Mounting the card into a low profile case isn't a problem with the low profile plug.
