StarTech 4 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter w/ 2 Dedicated 5Gbps Channels - UASP - SATA / LP4 Power

Enhance your computer’s connectivity with the StarTech.com PEXUSB3S42V 4-Port PCIe USB 3.2 Gen 1 card, designed to add four high-speed USB ports to any PCIe x4-enabled system. Featuring two independent channels, this card ensures dedicated bandwidth for two ports at 5 Gbps each, effectively doubling the total available bandwidth to 10 Gbps. This architecture minimizes performance bottlenecks when multiple devices are connected, providing faster data transfers and improved efficiency. The card supports UASP (USB Attached SCSI Protocol), enabling transfer speeds up to 70% faster than standard USB 3.2 Gen 1 connections by allowing multiple commands to process simultaneously. This results in quicker read/write operations, making it ideal for data-intensive tasks and high-performance peripherals. The card includes an optional SATA or LP4 power connector, delivering up to 900mA per port, which is essential for high-power USB devices and bus-powered peripherals. Compatible with USB Battery Charging Specification 1.2 (Apple Mode), it allows faster charging for iPhones, iPads, and other compatible devices. The PCIe card is fully compliant with USB 3.2 Gen 1 standards and backward compatible with USB 2.0 and 1.1 devices, ensuring broad compatibility with existing peripherals. It supports plug-and-play operation with hot-swap capabilities, allowing you to connect or disconnect devices without shutting down your system. Designed with versatility in mind, the card comes with both standard and low-profile brackets, making it suitable for both full-size and small form-factor computers. Backed by a two-year warranty and lifetime technical support from StarTech.com, this expansion card offers a reliable and efficient solution to upgrade your system’s USB connectivity. Whether for professional data transfer, device charging, or expanding peripheral support, the PEXUSB3S42V provides a robust, high-performance interface to meet your needs.
