The StarTech.com PEXUSB314A2V2 is a PCIe expansion card that adds four USB-A ports, each supporting up to 10Gbps; it suits desktop PC or server users who need faster connections for USB storage and other peripherals. Bandwidth depends on the PCIe slot and is shared when ports are used together.

Recommended For

  • Desktop users who regularly transfer large files between external SSDs or NVMe enclosures and want four additional USB-A ports, with separate controllers helping distribute storage traffic across two port pairs.
  • Workstation or server users who have run short of onboard USB-A ports and have an available PCIe x4-or-larger slot for adding four external connections.
  • Users who connect a mix of USB storage devices and peripherals and want a card that supports USB 10Gbps devices as well as older USB 5Gbps and USB 2.0 devices.
  • Desktop builders using Windows, macOS, or Linux who need extra USB-A ports and are comfortable installing an internal PCIe card; supplemental SATA power is available if the ports need additional power from the system.
