Two-port USB 3.0 PCIe x1 card

The Syba SD-PEX20158 adds two USB 3.0 ports to a desktop PC through a single PCI-Express x1 slot. It uses the Etron EJ168A controller and complies with the PCI-Express 2.0 base specification and the xHCI 1.0 standard. A low-profile bracket is included for compact cases, and a driver CD supports installation on Windows XP, Vista, 7 and Server 2008.

Desktop owners needing extra USB 3.0 ports

This card suits anyone with a free PCIe x1 slot who wants to connect external drives or peripherals at up to 5 Gbps throughput. It is backward compatible with USB 2.0, 1.1 and 1.0 devices. Builders whose motherboards lack a spare PCIe x1 slot or who require more than two additional ports should consider a different solution.

Internal +5 V power connector

An onboard HDD power connector supplies extra +5 V current to the two USB ports, ensuring stable operation for bus-powered devices. The card weighs 0.1 units and ships with the controller, low-profile bracket, driver CD and user manual.

Questions about this item

What is included in the box and do I need to buy anything extra to install the SD-PEX20158?

The box contains the USB 3.0 PCIe x1 controller card, a driver CD, a user manual, and a low-profile bracket. No extra parts are required for a standard installation.

The card uses the Etron EJ168A chipset — how does that affect which version of Windows I can run?

The driver CD supports Windows XP, Vista, 7 and Server 2008. Newer Windows versions may install generic drivers automatically, but the supplied media covers only those listed systems.

The headline speed is 5 Gbps — what throughput can I expect when the card is running in a PCI-Express 2.0 x1 slot?

The PCI-Express 2.0 x1 link provides enough bandwidth for the card to reach its 5 Gbps USB 3.0 rating, so real-world transfers approach that figure with fast drives.
