Add internal and external USB 3.0

This STARTECH PEXUSB3S11 expansion card adds one internal and one external SuperSpeed USB 3.0 port to a desktop computer through a PCI Express slot. It supports data transfer rates up to 5.0 Gbps and includes a SATA power connector for high-powered devices. UASP support is provided for improved storage performance. The card is designed for versatile peripheral connection.

Suits builds needing mixed USB locations

Builders who need both an internal header for front-panel access and an external rear bracket port will find this dual-port layout convenient. Systems limited to PCI Express Gen 1.0 slots will see throughput capped at 2.5 Gbps instead of the full 5.0 Gbps. Users requiring more than two USB 3.0 ports should consider alternative solutions.

Throughput depends on PCIe generation

The single specification that decides suitability is the host slot generation: PCI Express Gen 2.0 delivers the advertised 5.0 Gbps, while Gen 1.0 limits the card to 2.5 Gbps maximum throughput.

Questions sur cet article

Does the card need a SATA power connector to run high-powered USB devices?

Yes, the board includes a SATA power connector that can supply extra current to the internal or external USB 3.0 ports when required.

What is the first driver step after inserting the card into a PCI Express slot?

Install the driver for Windows XP, Vista, 7 or Server 2003/2008 R2 before connecting any USB 3.0 devices, otherwise the ports will not enumerate at 5.0 Gbps.

Will the internal USB 3.0 header still work if I never attach the optional SATA power lead?

The internal port functions for low-power devices without the SATA lead, but high-power peripherals need the extra supply to operate correctly.
