StarTech PEXUSB3S23 2-Port PCIe USB 3.0 Card

Expand desktop connectivity with a PCIe USB 3.0 adapter built for practical system upgrades. The StarTech PEXUSB3S23 adds two USB 3.0 ports through a PCI Express slot, giving older or port-limited systems the bandwidth needed for modern peripherals, external drives, and high-throughput accessories. With SuperSpeed USB 3.0 performance up to 5 Gbps, it helps reduce bottlenecks when moving large files or connecting multiple devices. This card is a straightforward way to extend the life and usefulness of a workstation or business desktop. The included low-profile, half-height bracket makes it suitable for compact enclosures where space is tight, while the PCIe interface keeps installation clean and internal. For IT teams standardizing desktop refreshes or adding ports to systems that were built before USB 3.0 became common, this card offers a targeted upgrade path without changing the platform. It is a practical fit for office desktops, lab systems, and service workstations that need reliable USB expansion. Instead of relying on external hubs or replacing hardware, you get direct motherboard-level connectivity with the speed and stability expected in managed environments.
