Upgrade your computer to the faster speed of USB 3.1, by adding two 10Gbps USB Type-A ports. This USB 3.1 card prepares you for the next generation of USB performance, adding two USB-A ports to your desktop with a combined bandwidth up to 10Gbps. Now you can access USB 3.1 Gen 2 peripherals at twice the speed of traditional USB 3.0 (USB 3.1 Gen 1) devices.
With greater bandwidth you can save time and avoid the performance bottlenecks often associated with other connectivity technologies.
Faster USB performance
By adding 10Gbps USB ports to your computer, you can harness the speed of USB 3.1 Gen 2 and rest assured you're ready for both current and future high-bandwidth USB-A devices.
With higher data throughput, this PCI Express USB 3.1 card is a necessity for external hard drives, hard drive enclosures, and many other USB 3.1 peripherals. Plus, the USB card integrates a SATA power connector to support high-powered devices, making it ideal for use with large external storage solutions. (The card requires a connection to your computer's SATA power connector.)
For more flexibility, you can couple the card with a USB-C to USB-A Cable (USB31AC1M) and connect your USB Type-C™ devices.
Compatible with older USB devices
Connecting older peripherals isn't a problem. This versatile USB 3.1 Gen 2 (10Gbps) card is backward compatible with legacy USB 3.0/2.0 devices that use the common USB Type-A port, so you can eliminate the added expense and aggravation of purchasing new devices.
Easy to install, in virtually any Windows based PC
The USB 3.1 card offers hassle-free installation with no additional software or drivers required in natively supported Windows® 10, 8.1, and 8 operating systems. Plus, the high-quality card includes both standard-profile and low-profile/half-height brackets, making it easy to install in full or small form-factor PCs or servers.
The PEXUSB312A is backed by a StarTech.com 2-year warranty and free lifetime technical support.
