Product Data Sheet / Brochure

By adding three types of USB ports in one combo card, you can free up space in your PC case, and eliminate the
nuisance of having different cards for different USB devices.
With two internal motherboard-style headers, this dynamic USB 3.1 card is perfect for upgrading or building your own
computer. If your existing headers are occupied, or if you don't have any motherboard headers, you can connect front
panel hubs or card readers using this versatile alternative to costly motherboard or computer upgrades.
Connecting your older peripherals isn't a problem. This 5-port USB 3.2 card is backward compatible with legacy USB
3.0, 2.0 and 1.1 devices, so you can eliminate the added expense and aggravation of purchasing new devices.
PEXUSB312A1C1H is backed by a StarTech.com 2-year warranty and free lifetime technical support.
Note: The card does not support DP alt mode or USB Power Delivery.
