StarTech PEXUSB312A3 USB 3.2 Gen 2 PCIe Card

Add high-speed USB expansion to a desktop that needs more than basic onboard connectivity. The StarTech PEXUSB312A3 uses an ASM3142 controller on a PCIe 3.0 x2 interface to deliver two USB-A ports with up to 10 Gbps per port. That makes it a strong fit for external SSDs, high-throughput peripherals, and workstation environments where transfer time matters. UASP support helps compatible storage devices perform more efficiently, while support for mixed-speed devices allows the card to handle USB 3.0 and USB 2.0 peripherals on the same adapter. A SATA power header provides up to 4.5 W per port, helping support connected devices that need more than bus power alone. The included full- and low-profile brackets make it easier to standardize across tower and small-form-factor systems. This is the kind of expansion card that earns its place in a professional build: precise, fast, and practical. For IT teams upgrading user workstations, imaging stations, or content workflows, it adds modern USB bandwidth without changing the platform. It is a focused hardware upgrade for environments that value speed, compatibility, and clean integration.
