The FebSmart FS-H2-Pro USB 3.0 expansion card is designed to add two internal 19-pin USB 3.0 headers to a desktop PC via a PCI Express slot. It delivers a data transfer rate of up to 5Gbps, enabling efficient connectivity for internal devices such as front panel USB ports, card readers, or USB hubs. This solution is suitable for users who need additional internal USB 3.0 ports for building or upgrading a system.

The card incorporates FebSmart self-powered technology, which draws power directly from the PCI Express bus. This eliminates the need for an extra power supply connection, simplifying installation inside the chassis. It is compatible with both Windows and Linux operating systems, making it a versatile component for a wide range of desktop platforms.

The hardware supports plug-and-play operation under most modern OS environments without requiring additional drivers. Constructed with a standard PCI Express x1 interface, the card works in x1, x4, x8, and x16 slots. The PCB uses durable materials and solid soldering to maintain stable performance over extended use.

The two 19-pin USB 3.0 connectors are positioned to fit neatly in typical tower cases, and the low-profile design does not obstruct adjacent components. Build quality focuses on reliable signal integrity and long-term durability. At a very affordable price point, this expansion card offers a cost-effective way to add high-speed internal USB 3.0 ports.

It is suited for desktop users who want to enable front panel USB 3.0 functionality or expand internal connectivity without investing in a new motherboard. The self-powered feature and broad OS support make it a practical choice for both home and office PC setups.
