Discontinued and replaced by PEXUSB311AC3 - Dual Port USB 3.1 Card - 1x USB-C - 1x USB-A 10Gbps per port - Expansion Card - USB 3.1 PCI-E Card - USB 3 PCI
Product ID: PEXUSB311AC2
This USB 3.1 card lets you add one USB-C port and one USB-A port to your computer, through a PCI Express slot. It
enables you to upgrade your current system by adding two USB 3.1 Gen 2 ports to your computer and giving you
access to data transfer speeds up to 10Gbps per port.
Plus, by adding one USB-C and one USB-A port to your PC, you can easily connect legacy, modern, and future USB
devices, regardless of the USB connector type.
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 and USB-C devices.
With higher data throughput support, this USB 3.1 PCIe card is a necessity for external drives, , and many other USB
3.1 peripherals. Plus, the USB card includes an optional SATA power connector to connect to your system power
supply and deliver up to 900mA of power per port to USB 3.1 bus-powered devices (500mA for USB 2.0). The card is
ideal for use with large external storage solutions.
Connecting older peripherals isn’t a problem. This versatile dual-port USB 3.1 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. You can also connect older devices on the USB Type-C port using a variety
of .
The USB 3.1 card is compatible with a broad range of Windows and Linux operating systems. Plus, the high-quality
card includes both standard-profile and low-profile brackets, making it easy to install in full or small form-factor PCs
and servers.
The PEXUSB311AC2 is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Note
The card's USB-C port is a standard data throughput port. It does not
support DP Alt Mode or USB Power Delivery.
The maximum throughput of this card is limited by the bus interface.
PCI Express Gen 1.0 max throughput is 2.5Gbps. PCI Express Gen
2.0 max throughput is 5Gbps. PCI Express Gen 3.0 max throughput is
10Gbps.
The available bandwidth (10Gbps) is shared equally between the two
ports.
