2X Dedicated USB 3.0 5Gbps Channel,10Gbps Bandwidth,4-Ports Superspeed 5Gbps USB 3.0 PCIE Expansion Card
FebSmart FS-2C-U4-Pro is a PCIE X4 interface to 4X superspeed 5Gbps USB 3.0 ports expansion card. It is based on 1X ASMedia ASM1806 10Gbps PCIE bridge controller and 2X ASMedia ASM1042 5Gbps USB 3.0 host controller, will compatible with ARM, AMD, and Intel hardware platforms. It will provide 2X independent USB 3.0 5Gbps channels, 10Gbps total banwidth on 2X external USB-A and 2X internal USB-A interface. 1X external USB 3.0 port and 1X internal USB 3.0 port will share 1X USB 3.0 5Gbps bandwidth. 4X USB 3.0 Ports will share 10Gbps bandwidth. It is built in FebSmart Self-Powered Technology, no need to plug any additional power cables from Desktop PCs power supply unit. Allow each USB 3.0 channel two USB 3.0 ports get 5V/3A 15W (5V/6A 30W in total) max power supply from motherboard directly for connected high power consumption USB 3.0 devices. It is mainly used on Desktop PCs, Working Stations, and NAS data centers for high-bandwidth USB 3.0 devices which including indusrial cameras, VR-Systems, USB 3.0 NVME enclosures, live broadcast devices, USB 3.0 SSD/HDD enclusures, USB 3.0 video adapters and USB 3.0 universal docking stations. It also works with normal USB-A interface devices such as USB keyboard, USB mice, USB speakers, USB KVM switch, USB HUB, USB flash drive, printers, game pad, smart phone, tablet and more USB-A devices.

What is FebSmart Self-Powered Technology?
FebSmart Self-Powered Technology is a new solution to add more power supply on USB 3.0 expansion cards. The old version PCI Express USB 3.0 cards need to plug power cables from Desktop PC’s power supply unit. Even added on additional power, sometime it still lacks power when running few high power-consuming devices simultaneously such as USB HDD/SSD enclosures and USB NVME enclosures. PCI Express slot can provide 75W max power almost 12V/6.25A for PCIE devices. FebSmart add 2X voltage transformer on 2X channel USB 3.0 card. 2X independent USB 3.0 channel has 2X way power supply. Each way power supply will pick up 12V/1.25A power and convert to 5V/3A 15W. So, each USB 3.0 channel 1X Internal USB 3.0 port and 1X external USB 3.0 port will get 5V/3A 15W max power supply for USB 3.0 devices. Most of the high-power consumption devices just need 4~8W which means this USB 3.0 expansion card can light up 4X high power-consumption devices simultaneously in full speed. FebSmart built 4X electronic safty fuse, 2X voltage stable inductance and 4X voltage stable capacitors on the board, will protect users’ data and USB 3.0 devices. Never burn USB 3.0 device and never lost data. Add 2-channel 4-Ports superspeed USB 3.0 expansion card on Desktop PCs. Enjoy more stable,superspeed and safe USB 3.0 connection with FebSmart.

ATTENTION:
1. Must makesure Desktop PCs have one empty PCIE X16 slot before purchase.
2. Must install driver on Windows 7 (32/64bit) and previous systems.
3. Slim PC users need change to low profile bracket by hand.
4. Please use USB 3.0 devices test connection speed, or cannot get the peak speed.
