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.

USB speed chart that showcases the performance advantage of USB 3.1 at 10Gbps when compared to older USB standards

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.

Wont work in Dell Servers

Trying to use for USB 3.1 drive dock on a backup server. The card needs power, no power leads on most Dell servers for aux power to pcie cards. The Startech USB 3.0 pcie card did not need aux power if the drive was independently powered. Request a 3.1 card that does not need aux power, even if that violates the 3.1 standard.

Exactly what we we're needing

I am one of the " IT " guys Orthopedic Appliance Company here in Asheville NC. Our Dell server has those 2.0 USB ports. Backups being that they are encrypted we're taking 8hrs+/-. Even though backup we're scheduled after hours, it would run into the following day by a few hrs. Ordered the 3.0+ Pcie add-on card, and now complete backups are taking less than 5 and are completed before the staff returned the following morning and are able to be more productive because the local server isn't being bogged down from backups running​. 18 staff members running pervasive database applications along with remote desktop really put a strain on Everything. Best money spent.
