Overview

This low-profile PCIe x2 card adds two internal USB 3.1 ports through a single 19-pin header. It suits builders who need front-panel USB 3.1 connectivity with reliable signal integrity over longer cables.

Design and Build

The card uses a black PCB with a silver bracket. A low-profile bracket is included for small form factor cases. It installs into any available PCIe x2 or larger slot.

Performance and Use

Two onboard redriver chips extend reliable 10 Gbps transfer rates to 2 meters, doubling the standard USB 3.1 cable limit. The card is backward compatible with older USB standards and supports UASP for faster storage throughput.

Compatibility and Installation

Native XHCI support allows driverless installation on modern operating systems. The single 19-pin internal header connects to compatible front panels or drive bay adapters.
