## Summary description

The StarTech.com 4 Port PCI Express USB 3.0 Controller Card Adapter (PEXUSB3S4V) offers four USB 3.2 Gen 1 ports with a maximum data transfer rate of 5 Gbit/s.

## Long description

The StarTech.com PEXUSB3S4V Controller Card Adapter adds four external USB 3.2 Gen 1 (USB 3.0) ports to any PCI Express-enabled desktop or small form factor computer. The card supports data rates up to 5 Gbps, remains backward compatible with USB 2.0/1.x devices, and includes a SATA power connector to provide up to 900 mA per port when connected to the system power supply. The low-profile design with a stacked port layout allows all four ports to be externally accessible while fitting into standard and low-profile systems.
Advantages
The adapter delivers high-speed USB 3.2 Gen 1 connectivity with UASP (USB Attached SCSI Protocol) support for improved transfer efficiency and reduced CPU utilization. When paired with a UASP-capable enclosure and a compatible operating system, UASP can achieve significantly faster read and write performance compared to traditional USB bulk-only transport. The card is powered via a SATA power connector to support higher-current devices and includes a low-profile bracket for small form factor installations. It is backed by StarTech.com two-year warranty and lifetime technical support.
Suitable for
Adding external USB 3.2 Gen 1 ports to desktop or small form factor PCs
