4 Port USB 3.1 PCIe Card – 10Gbps – 4 USB Ports with Two Dedicated Channels – PCI Express Expansion Card

This USB 3.1 PCIe card allows you to add four USB Type-A ports to your computer, through one PCI Express slot. With two independent 10Gbps channels, this card makes it easy to upgrade your PC to the higher speed of USB 3.1 Gen 2, so you can access your newest peripherals at twice the speed of conventional USB 3.0 cards (USB 3.1 Gen 2). 1).

Faster USB performance
When multiple devices are connected, traditional single-bus USB cards share the maximum bandwidth between all ports. Since two host controller chipsets are used, which are shared across two ports instead of four, this 4-port USB 3.1 card dedicates up to 10Gbps to each set of two USB ports. Reduces performance bottlenecks and doubles the total available bandwidth to 20Gbps.

By adding 10Gbps USB ports to your computer, you take full advantage of the speed potential of USB 3.1 Gen 2 technology, ensuring current and future compatibility with high-bandwidth USB-A devices.

With higher data transmission performance, this PCI Express USB 3.1 card is a must for external hard drives, disk drive enclosures, as well as many other USB 3.1 peripherals. Additionally, the USB card includes an optional SATA or LP4 power connector that allows you to connect to your system’s power supply and get up to 900mA of power per port for USB 3.1 bus-powered devices (500mA for USB 2.0). This card is ideal for high-volume external storage solutions.

Shared bandwidth
This 4-port USB 3.1 card includes dual independent channels with your computer and 10Gbps shared bandwidth between two USB ports.

Each set of two ports offers 10Gbps bandwidth sharing. If a single device accesses a channel, the card offers data transfer rates of up to 10Gbps to the device. If two devices access the channel simultaneously, the 10Gbps bandwidth will be shared between both devices.

Space for four additional devices
With four external USB-A ports, it is possible to connect more devices to your computer. This card provides easy access to frequently used peripherals such as your USB memory (Flash) drives and external hard drives, as well as allowing connection to current and future high bandwidth USB-A devices.

For added flexibility, the card can be paired with a USB-C to USB-A cable (USB31AC1M), to connect it to your USB Type-C ™ devices.

Compatible with previous generation USB devices
Connecting with older generation peripherals is no longer a problem. This versatile USB 3.1 Gen 2 (10Gbps) card is backward compatible with previous generation USB 3.0 / 2.0 devices that use the common USB Type-A port, to avoid the hassle and additional expense of upgrades or the purchase of new devices.

Upgrade a previous generation PCIe-equipped desktop computer from USB 3.0 / 2.0 to USB 3.1 Gen 2 (10Gbps)
Expand the USB capacity of your system with four additional USB ports or install the card as an essential hardware component of a new computer to be mounted
Ideal for file backup, video editing, and data recovery using high-bandwidth USB 3.1 Gen 2 external storage solutions.
