5-Port USB 3.1 PCIe Card - 1x USB-C (10Gbps), 2x USB-A (5Gbps) + 1x 2-Port IDC (5Gbps)
Add an external USB Type-C and two external USB Type-A ports to your computer, plus an IDC header port that can provide two internal USB 3.0 ports
Product ID: PEXUSB312EIC
- Connect a USB-C device, plus a range of other USB devices, to your computer, regardless of their speed or connector type
- Offers a high-performance USB-C port (10Gbps), two USB-A ports (5Gbps), and one 20-pin internal IDC motherboard header that can provide two USB-A ports (5Gbps)
- Works with your existing USB 3.0 and USB 2.0 devices, for cost-effective backward compatibility
This 5-port USB 3.1 combo card makes it easy to add to the performance and connectivity of your computer. It’s one of the only USB 3.1 cards to offer a USB Type-C™ port (10Gbps), traditional USB Type-A ports (5Gbps), and a motherboard header.
By offering a range of USB port types, you can easily connect a variety of modern and legacy USB devices, both inside and outside your computer.
Because the card offers a 10Gbps USB-C™ port (USB 3.1 Gen 2), you can save time and avoid the performance bottlenecks that are often associated with other connectivity technologies.
Work faster and prepare for the future
This versatile PCI Express combo card leverages the performance potential of USB 3.1 to help you work faster. The USB-C port offers a data throughput of up to 10Gbps, so you can spend less time waiting for file transfers to complete or for access to your external peripherals.
Plus, you can rest assured that you’re set for the future, as USB-C devices become more popular and more standardized.
Connect different types of USB devices
Now you can easily add a variety of types and speeds (generations) of USB ports to your desktop or server, using a single adapter card. The card features:
- One external USB-C port (USB 3.1 Gen 2 - 10Gbps)
- Two external USB-A ports (USB 3.1 Gen 1 - 5Gbps)
- One internal 20-pin IDC motherboard header port that can provide two internal USB-A ports (5Gbps)
With a range of port types, the card lets you bridge the gap between older and newer devices that use different connectors. You can simultaneously connect and access USB Type-A and USB Type-C devices, while using only a single PCI Express expansion slot.
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.

Frequently Asked Questions
Before You Buy
The USB expansion cards derive power from the PCI or PCI Express slot on the motherboard. When high-powered USB devices are connected to the USB expansion card, the power provided by the slot may not be enough to power all of the devices and you should connect additional sources of power. When you troubleshoot issues, you should connect an additional source of power.
Symptoms that you are experiencing power-related issues include certain devices not working correctly, not all of the devices working at the same time, and certain devices not working at all.
Examples of low-powered USB devices include USB mice, keyboards, and flash drives. An example of a high-powered USB device is an external hard drive that does not have an external source of power.
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.
USB-C is a type of USB connector that is capable of supporting the following:
- Data transfer speeds up to 10Gbps, if you use USB 3.1.
- Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
- Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).
If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-port-capabilities.
Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers.
