Overview
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.
Applications

Frequently Asked Questions
Before You Buy
Yes, it is required to use the included power connector with this card. Additional power is required above what the PCI or PCI Express slot on the motherboard is able to provide. If the power connector is not used with the card, the devices used with the card are not likely to function correctly, and the ports on the card will not be able to output the maximum amount of power USB is capable of.
USB 3.1 is the most recent version of the USB (Universal Serial Bus) standard for connecting computers and electronic devices. It is capable of data transfer speeds up to 10Gbps, and while it can use the USB-C connector type, it can also use a variety of other connector types. To achieve USB 3.1 transfer speeds, your USB host connection, cables, and device must all support USB 3.1. USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps).
USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps).
USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios:
- USB-B 3.1 cables are not compatible with USB-B 2.0 ports.
- Unless you use an adapter, USB-C ports or cables will not work with USB-A or USB-B ports or cables.
- Devices that require USB 3.1 transfer speeds of 10Gbps might not work with USB 3.0 or USB 2.0, or you might experience lower transfer speeds and impacted performance.
- Bus-powered USB devices that requires more power than what USB 2.0 can provide are not compatible with USB 2.0.
To transfer data at speeds of 10Gbps, you need to confirm that the following components in your setup support USB 3.1:
- The USB host connection
- The USB cable
- The USB device and any subcomponents (for example, a hard drive docking station and the hard drives in the docking station)
Note: USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). Devices that support USB 3.1 should have the USB 3.1 symbol on them. If the USB 3.1 symbol does not appear on your USB source or device, refer to the information provided by the manufacturer to confirm whether the USB source or device support USB 3.1.
