StarTech.com 4 Port USB 3.0 PCIe Card, 5Gbps, USB-A

The StarTech.com PEXUSB3S44V is a high-performance 4-port PCI Express USB 3.2 Gen 1 card, designed to add four dedicated 5Gbps USB ports to your PCIe x4-enabled PC. This expansion card employs independent port architecture, with each port operating on its own transmission channel, eliminating the performance bottlenecks common with traditional single-bus USB cards. By using four host controller chipsets, the card effectively quadruples the total available bandwidth to 20Gbps, ensuring faster file transfers and smoother operation even when multiple high-speed devices are connected simultaneously.

Enhanced with UASP support (USB Attached SCSI Protocol), this card delivers up to 70% faster performance than conventional USB 3.2 Gen 1 when paired with a UASP-compatible enclosure (requires a compatible OS). It is the ideal solution for upgrading an older PCIe-based system to USB 3.0 connectivity, allowing you to fully utilise the speed of modern USB devices. The card also provides optional LP4/SATA power connectors to power high-powered USB devices as needed, ensuring stable operation under load.

Designed and built for IT professionals, this 4-port USB 3.0 PCIe card includes a low-profile bracket for flexible installation in standard or small-form-factor cases. The card is compatible with a wide range of operating systems, including Windows Vista, 7, 8, 8.1, 10, 11, Linux 2.6.31 and up LTS versions, and Windows Server 2008 R2 through 2022. The package contents include a 4-port PCIe USB card, low-profile bracket, driver CD, and instruction manual. With multi-lingual technical assistance available, this card is a reliable and feature-rich expansion solution for any professional environment.
