Frequently Asked Questions

No. FebSmart Self-Powered Technology pulls power through the PCIe slot itself, delivering 5V/2A (10W) per port and 40W total with no SATA or Molex cable.
Does each of the four USB ports get its own 5Gbps?
No. The four USB-A ports share 5Gbps of total bandwidth from the single Renesas uPD720201 host controller, so copying to two drives at once splits that throughput.
Will this work on a Mac?
No. FebSmart lists this card as not supporting Mac OS X. It is designed for Windows, Windows Server, and Linux desktops and workstations.
Will it fit my small form factor PC?
Yes. The card ships with the full-height bracket installed and a low-profile bracket in the box, which you swap by hand for slim cases.
Can I install it in an older PC with only PCI slots?
No. It requires a PCIe x1 slot and will also seat in x2, x4, x8, or x16 slots on PCIe 1.x through 4.x boards. It does not work in legacy PCI slots.
