StarTech PEXUSB3S4V 4-Port USB 3.0 PCIe Expansion Card
Overview
The StarTech PEXUSB3S4V provides a straightforward solution to expand your system's connectivity by adding four external USB 3.0 ports. This PCIe card is designed to integrate seamlessly into either a standard or low-profile computer chassis, making it suitable for a wide range of desktop builds. It's particularly useful in environments where multiple USB devices require simultaneous connection, such as connecting external storage, high-resolution cameras, or other peripherals that demand higher bandwidth than USB 2.0 can provide. The PEXUSB3S4V model ensures your devices benefit from the full 5 Gbps data transfer rate offered by the USB 3.0 standard.
Compatibility
This PCIe USB 3.0 card is compatible with systems running Windows 7, 8, 10, 11, and Linux distributions. It requires an available PCIe x1 slot or larger (e.g., x4, x8, x16). The card itself adheres to the PCIe 2.0 specification, delivering the necessary bandwidth for its four USB 3.0 ports. It is designed for direct integration into motherboards supporting these PCIe standards.
Installation Notes
The PEXUSB3S4V supports a maximum power output of 900mA per port, adhering to the USB 3.0 specification. Ensure your system's power supply can accommodate the additional load. The card operates within an ambient temperature range of 5°C to 50°C (41°F to 122°F). Installation requires opening the computer chassis and seating the card into an appropriate PCIe slot. The low-profile bracket is pre-installed, but a full-height bracket is also included for standard computer cases.
