Two USB 3.1 Type-A ports on a PCIe 3.0 x4 card

The Syba SD-PEX20185 adds two USB 3.1 Type-A connectors to a desktop through a single PCI Express 3.0 x4 slot. An ASMedia ASM1142 host controller drives the ports at up to 10 Gbps and follows the xHCI 1.1 and USB 3.1 revision 1.0 specifications. A low-profile bracket is included for small-form-factor cases. Windows 10, 8.1, 8 and 7 are supported with the supplied driver CD.

Builders adding front-panel

This card suits anyone who needs exactly two additional USB 3.1 Type-A ports on a system with a free PCIe 3.0 x4 slot. It does not help buyers who want USB Type-C connectors, more than two ports, or internal USB headers. Systems without a compatible PCIe slot or running a non-Windows operating system should look elsewhere.

ASMedia ASM1142 controller with xHCI 1.1 compliance

The ASM1142 host controller implements the Intel eXtensible Host Controller Interface revision 1.1 and USB 3.1 revision 1.0, delivering 10 Gbps signalling on each Type-A port. That controller choice determines driver compatibility and the maximum throughput the card can sustain.
