## Summary description

The StarTech 2 Port PCI Express SuperSpeed USB 3.0 Card Adapter with UASP offers two USB 3.2 Gen 1 ports with a maximum data transfer rate of 5 Gbit/s. It features a low-profile design, supports various Windows operating systems, and is powered via SATA. Ideal for expanding USB connectivity in your PC.

## Long description

The StarTech PEXUSB3S24 PCI Express Card Adapter adds two SuperSpeed USB 3.0 (USB 3.2 Gen 1) ports to a PCIe-enabled desktop or small form-factor computer. The card supports an optional SATA power connection to deliver up to 900 mA per port to bus-powered USB 3.2 Gen 1 devices and maintains backward compatibility with USB 2.0 and 1.1 devices. The adapter includes both a standard profile bracket and a low-profile/half-height bracket for flexible installation.
Advantages
This PCIe USB 3.2 Gen 1 controller supports UASP (USB Attached SCSI Protocol), which can significantly increase transfer performance compared with traditional USB Bulk-Only Transport. When used with a UASP-capable enclosure and supported operating system, the card can deliver noticeably faster read/write speeds and reduced CPU utilization. The adapter complies with USB 3.2 Gen 1 standards for data rates up to 5 Gbps and is supplied with StarTech's 2-year warranty and free lifetime technical support.
Suitable for
Adding high-speed USB 3.2 Gen 1 ports to a desktop PC
Connecting external storage enclosures and SSDs
Upgrading older systems that lack SuperSpeed USB ports
Small form-factor or low-profile systems (uses included low-profile bracket)

How to use
Power off and unplug your PC, open the case and insert the PEXUSB3S24 into an available PCI Express slot. Secure the bracket with a screw and attach the SATA power cable from your power supply if you plan to power bus-powered devices that require additional current. Install the included low-profile bracket if using a small form-factor case. After closing the case, boot the system and allow the operating system to detect and install drivers; on supported systems you can enable UASP for improved performance. Verify the ports in Device Manager (Windows) or appropriate system tools on other OSes.
Usage recommendations
For best performance, use UASP-capable external enclosures and a supported operating system (for example Windows 8/8.1, Server 2012, or Linux kernel 2.6.37+). When connecting high-power bus-powered devices, attach the SATA power connector to ensure up to 900 mA per USB 3.2 Gen 1 port.
