The PCIUSB3S22 2-Port PCI to USB 3.2 Gen 1 Card enables you to connect USB 3.2 Gen 1 peripherals to a PC through a legacy PCI host bus, which doubles the data transfer speeds when used with USB 3.2 Gen 1 peripherals than would be possible with a USB 2.0 host connection - up to 1.3 Gbps (PCI bus limit). The card features an optional SATA power connection, which enables each port to supply up to 900mA of power to USB 3.2 Gen 1 bus-powered devices. By supporting a legacy (PCI) host connection, the card adds updated peripheral connectivity, without having to upgrade to a PCIe-equipped motherboard or rely on the backward compatibility of USB 3.2 Gen 1 peripherals. Guaranteed to provide reliable performance, the PCIUSB3S22 PCI USB 3.2 Gen 1 card is backed by lifetime warranty and free lifetime technical support. More from the Manufacturer
