Two-port USB 3.0 expansion card

This PCIe x1 card adds two external USB 3.0 ports to a desktop computer. It connects to the motherboard through a 19-pin internal header and draws auxiliary power from a 4-pin IDE connector. The board is suited for users who need extra front-panel or rear-panel USB sockets without replacing the motherboard.

Limited to two USB 3.0 ports and a single PCIe lane

The adapter provides exactly two Type-A ports, so systems requiring more than two additional connections will need a different solution. Bandwidth is constrained by the PCIe x1 interface, which can become a bottleneck when both ports transfer large files simultaneously. No internal USB headers are exposed on the bracket, limiting front-panel expansion options.

Highlights

Questions about this item

Will the PCI-E x1 slot and 19-pin header on this card work with my older motherboard that only has legacy PCI slots?

No, the card requires a PCI-E x1 slot and a 19-pin internal USB header; it is not compatible with legacy PCI slots.

How can I verify the two external ports are running at USB 3.0 speeds after installation?

Connect a USB 3.0 flash drive and check the transfer rate or open Device Manager to confirm the controller lists SuperSpeed USB 3.0.
