StarTech Controller Card PEXUSB314A2V2 4Port USB PCI Express Card with 2 Controllers

Description

This PCIe USB 3.2 Gen 2 controller card installs into an available PCI-Express x4 slot in your computer and enables you to upgrade your current system by adding four SuperSpeed USB-A (10Gbps) ports. The card features dual ASM3142 controllers with up to 20 Gbps of total bandwidth shared across all 4 ports.

Add Four 10 Gbps USB Type-A Ports to Your Desktop Computer

The controller card enables you to connect four USB-A Gen 2 (10 Gbps) devices to your desktop computer. The USB-A ports are ideal for connecting USB devices such as external hard drives and solid state drives or powering and syncing your mobile devices. The USB-A ports provides up to 4.5W (5V/0.9A) of power per USB port, and are backward compatible with USB 3.2 Gen 1 (5 Gbps), and USB 2.0 (480 Mbsp) devices.

Note: USB 3.2 Gen 2 (10 Gbps) is also know as USB 3.1 Gen 2 (10 Gbps), and USB 3.2 Gen 1 (5 Gbps) is also know as USB 3.0 and USB 3.1 (5 Gbps).

SuperSpeed USB 3.2 Gen 2 (10 Gbps) Performance

The USB 3.2 Gen 2 card features dual ASMedia ASM3142 host controllers that utilizes x4 lanes of the PCIe 2.0 bus, making the card capable of speeds up to 10 Gbps on each port, and enabling fast access to high-performance devices like NVMe drives and SSDs. The controller cards support Multiple INs to reduce bandwidth loss when multiple devices are connected, even when connected through a USB Hub (Note: The USB hub must also support this feature). The card also supports UASP for improved performance with storage devices.

Wide Installation Compatibility

This add-on card includes a full-profile installation bracket ensuring you can install it into full-profile PCIe 2.0 x4 slots. For wide platform support the card is compatible with Windows, Linux and macOS. For hassle-free installation the drivers install automatically on computers running Windows 8 or higher.

Note
This card can share up to 20Gbps of bandwidth (up to 10Gbps, per port). However, the maximum throughput of the card is limited by the maximum throughput of the PCI-Express interface its connected through
The available bandwidth (10Gbps) is shared equally between the two ports.
