.com PEXUSB3S4V 4-Port PCIe SuperSpeed USB 3.0 Controller Card with UASP, 5Gbps, SATA Power (TAA)

Expand a PCI Express slot with four external SuperSpeed USB 3.0 ports using the .com PEXUSB3S4V. Supports transfer speeds up to 5 Gbps while remaining backward compatible with USB 2.0 and USB 1.x devices. Integrated UASP support improves transfer efficiency by allowing multiple commands to be handled concurrently, boosting performance for compatible storage devices. The ports are arranged in a stacked layout (one above the other) so all four remain externally accessible yet fit inside low-profile computer cases. A built-in SATA power connector supplies increased current to attached devices — up to 900 mA per USB 3.0 port (500 mA when operating as USB 2.0). TAA compliant.
