StarTech 2 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter with UASP

Under the hood of the PEXUSB3S25 2-Port PCI Express USB 3.0 Card Adapter, you'll find a high-speed, reliable solution for expanding your computer's connectivity. This efficient and user-friendly device allows you to add two SuperSpeed USB 3.0 ports to your PCI Express-enabled computer system, enhancing its versatility and performance.

The adapter comes with an optional LP4 power connector, capable of delivering up to 900mA of power per port to USB 3.0 bus-powered devices, and 500mA for USB 2.0 devices. This ensures your connected peripherals receive ample power for optimal performance.

One of the standout features of this durable PCIe card adapter is its support for UASP (USB Attached SCSI Protocol). This advanced technology allows the USB 3.0 controller to perform up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure. Please note that UASP support may vary depending on your operating system.

UASP technology optimizes data transfers by processing multiple commands simultaneously. This efficient protocol, superior to the traditional USB BOT (Bulk-Only Transport), significantly increases transfer speeds, reducing wait time on data transfers.

The PCIe USB 3.0 adapter complies with USB 3.0 standards, supporting data transfer speeds of up to 5 Gbps. It also maintains backward compatibility with existing USB 2.0 / 1.1 devices, ensuring your older peripherals won't be left behind.

For added convenience, the controller card comes with a standard profile bracket and includes a low-profile/half-height bracket. This makes it suitable for installation in small form-factor computers, making it a versatile addition to any system.

The PEXUSB3S25 2-Port PCI Express USB 3.0 Card Adapter is an excellent choice for upgrading an older PCIe-based system from USB 2.0 to USB 3.0 connectivity. It's also perfect for expanding your system's USB capabilities with two additional external ports. Connect external hard drives, CD/DVD drives, MP3 players, printers, scanners, webcams, game controllers, digital cameras, and more to enhance your computer's functionality.
