The Startech PEXUSB3S42V PCI card is a solution designed to expand computer connectivity by adding four USB 3.2 Gen 1 ports with two independent high-speed channels, allowing a combined total transfer rate of up to 10 Gbps (5 Gbps per port pair), optimizing performance compared to traditional USB cards that share a single bus. This PCI Express 3.0 card features a standard and low/medium profile (Full-height/Low-profile compatible) and connects to PCIe x4 slots. It includes optional additional power via a SATA or 4-pin Molex connector, ensuring up to 900 mA per port for devices with high power demands, far exceeding standard USB 2.0 power. It also supports UASP (USB Attached SCSI Protocol), which improves efficiency and increases read and write speeds by up to 70% and 40% respectively, reducing latency and system resource usage by up to 80%, when used with compatible devices and operating systems. Compatible with USB 3.2 Gen 1 standards, it is backward compatible with USB 2.0 and USB 1.1, and also supports fast charging for Apple devices under USB 1.2 mode, useful for iPhone and iPad. The card includes dual Renesas / NEC µPD720202 chips and integrates USB Type-A and USB-C connectors, offering versatility to connect multiple modern devices and peripherals. Its compact dimensions (15 mm wide, 167 mm deep, and 120 mm high) allow easy installation in standard or compact desktop PCs. This component is CE and FCC certified, ensuring compliance with European and North American regulations. In summary, the Startech PEXUSB3S42V is an advanced and reliable technical option for professional or personal users needing to expand USB connectivity with high performance and power flexibility in their workstations or desktop systems.
