Product Overview

SuperSpeed USB 3.0 Adapter

The PEXUSB3S25 2-Port PCI Express USB 3.0 Card lets you add two USB 3.0 ports to your PCI Express-enabled computer system, with an optional LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0).

Increased Transfer Speeds

Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP is not supported by all operating systems). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimises transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers.


The PCIe USB 3.0 adapter is compliant with USB 3.0 standards for data transfer speeds up to 5 Gbps, while still offering backward compatibility with existing USB 2.0 / 1.1 devices. For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.

• Provides two external USB 3.0 ports with UASP support.
• Supports data rates up to 5 Gbps.
• Compliant with PCI Express 2.0 specifications.
• Optional LP4 power connector provides up to 900mA per USB port.
• Supports USB Battery Charging Specification 1.2.
• Fully compliant with USB 3.0 rev 1.0 and Intel xHCI rev 1.0 specifications.
• Backward compatible with USB 2.0 and USB 1.0/1.1 devices.
