PCIe USB 3.1 expansion card

This Syba SI-PEX20189 card adds external USB connectivity through a PCI Express 2.0 dual-lane slot. It provides both Type-A and Type-C ports operating at the USB 3.1 standard with a 10 Gbps data transfer rate. A low-profile bracket is included for installation in compact chassis.

Builders needing front-panel USB 3.1

The card suits system builders who want to add 10 Gbps Type-A and Type-C ports to a desktop with a free PCIe x4 slot. It also supports 5 V / 3 A charging through the Type-C port. Buyers whose motherboards lack a PCI Express 2.0 dual-lane slot or who require internal USB headers should look at other solutions.

PCI Express 2.0 dual-lane interface

The card installs in a PCI Express 2.0 dual-lane slot using an x4 form factor, which determines whether it fits the target motherboard. Windows 10 driver support is provided via the included disc. Verify that the system has a compatible slot before purchase.

Questions about this item

Does my motherboard need a PCI-Express 2.0 x4 slot for this SI-PEX20189 card?

Yes, the card uses a PCI-Express 2.0 Dual-Lane interface in an x4 form factor, so an available x4 slot is required.

Will USB 3.0 devices run at 10 Gbps on the Type-A and Type-C ports?

No, USB 3.0 devices operate at their native 5 Gbps; the 10 Gbps rate applies to USB 3.1 devices connected to these ports.

How can I verify the card is delivering 10 Gbps after installation?

Connect a USB 3.1 device and check the link speed in Device Manager or run a benchmark that reports a sustained throughput near 10 Gbps.
