USB 3.0 Front Panel 4 Port Hub – 3.5in or 5.25in
Bay
Product ID: 35BAYUSB3S4
The 35BAYUSB3S4 3.5-inch Front Bay to 4-Port USB 3.0 Panel Hub turns any available 3.5-inch computer
case front bay into a 4-Port USB 3.0 hub.
Using only a single USB connection, this front panel hub adds four easily accessible USB ports to the front
of your computer case through a 3.5-inch bay, or through a 5.25-inch bay using the optional Front Bay
Bracket Adapter (BRACKETFDBK) accessory. Each of the added ports is compliant with the USB 3.0
standard which supports up to 5 Gbps of bandwidth (10x faster than the USB 2.0 standard) and up to
900mA of power.
Accessorize with the PEXUSB3S11 PCI Express card to provide an internal USB 3.0 port, so as to keep the
external ports free for external devices. Backed by a StarTech.com 2-year warranty and free lifetime
technical support.
