StarTech PEXUSB314A2V2 USB 3.2 Gen 2 PCIe Card

Add high-speed USB capacity where it matters most: at the PCIe bus. The StarTech PEXUSB314A2V2 installs in a full-profile PCIe 2.0 x4 slot and delivers four USB-A ports with SuperSpeed 10 Gbps performance per port. Two ASM3142 controllers provide two ports per controller, helping distribute bandwidth across mixed-speed devices instead of forcing every device through a single controller path. That architecture makes this card a strong fit for SSDs, HDDs, NVMe enclosures, and other peripherals that benefit from sustained transfer rates. Optional SATA power support gives compatible devices additional power headroom, up to 4.5 W per port. It is designed for Windows, Linux, and macOS environments, making it practical for IT teams standardizing across mixed fleets. For systems that need more than a basic USB add-in card, this model offers the kind of throughput, controller design, and power flexibility that justify the upgrade. It is a straightforward way to extend a workstation or desktop with ports that can keep pace with modern storage and accessory demands.
