4-Port USB 3.1 (10Gbps) Card - 4x USB-A with Two Dedicated Channels - PCIe
Add four USB Type-A ports with two independent 10Gbps channels to your computer, through a PCI Express slot
Product ID: PEXUSB314A2V
This USB 3.1 PCIe card lets you add four USB Type-A ports to your computer, through a PCI Express slot. With two independent 10Gbps channels, the card makes it easy to upgrade your PC to the faster speed of USB 3.1 Gen 2 so that you can access newer peripherals at twice the speed of traditional USB 3.0 (USB 3.1 Gen 1) cards.
Faster USB performance
When multiple devices are connected, traditional single-bus USB cards share your maximum bandwidth between all ports. By employing two host controller chipsets, shared across two ports rather than four, this 4-port USB 3.1 card dedicates up to 10Gbps for each set of two USB ports. It reduces performance bottlenecks and doubles your total available bandwidth to 20Gbps.
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 support, 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 includes an optional SATA or LP4 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.
The 4-port USB 3.1 card features dual independent channels to your computer and shares 10Gbps of bandwidth between two USB ports.
Each set of two ports shares a combined bandwidth of 10Gbps. If a single device is accessing the channel, the card will provide data transfer rates of up to 10Gbps to the device. If two devices are accessing the channel simultaneously, the 10Gbps of bandwidth will be shared between both devices.
Room for four additional devices
With four external USB-A ports you can connect more devices to your computer. The card provides easy access to commonly-used peripherals such as your flash drive and external hard drive and allows you to connect to both current and future high-bandwidth USB-A devices.
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.
The PEXUSB314A2V is backed by a StarTech.com 2-year warranty and free lifetime technical support.

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.
