Add four USB 3.0 ports with four independent channels, LP/SATA power, and charging support to your PC through a PCI Express slot

The PEXUSB3S44V 4-Port PCI Express USB 3.0 Card lets you add four, dedicated 5 Gbps USB 3.0 ports to your PCIe x4-enabled PC. This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers.

Increase the efficiency of your USB 3.0 devices with four dedicated bus channels

When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports. By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps.

Power high-powered USB devices as necessary, with the optional LP4 or SATA power connector

For high-power USB devices, this PCIe USB 3.0 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 3.0 bus-powered devices (500mA for USB 2.0).
