Add four high-speed USB 3.0 ports to your PC or server via PCIe.
Connecting multiple high-speed peripherals often exhausts available USB ports on standard motherboards, creating bottlenecks for data-intensive tasks. The LRSU9A71-4A PCIe USB 3.0 Host Adapter resolves this by expanding connectivity without occupying valuable external hubs.
Equipped with the NEC uPD720201 controller, this card delivers SuperSpeed data rates up to 5Gb/s across four independent ports. This bandwidth ensures rapid transfer of large files from external storage or digital cameras, significantly reducing wait times compared to USB 2.0 connections. The inclusion of a 15Pin SATA power plug guarantees stable power delivery for demanding devices.
Ideal for workstations requiring reliable connections for printers, cameras, and storage arrays, this adapter supports legacy USB 1.1/2.0 devices alongside modern USB 3.0 hardware. Its compliance with PCI Express 2.0 x1 standards and inclusion of both low-profile and full-height brackets make it versatile for various computer form factors.
Adds four USB 3.0 ports to your system for connecting multiple peripherals simultaneously.
Supports data transfer speeds up to 5Gbps, ten times faster than USB 2.0.
Backward compatible with USB 2.0 and 1.1 devices while supporting USB 3.0 SuperSpeed.
Includes a 15Pin SATA power connector to ensure stable operation for power-hungry devices.
