connector)
This connector is used to support the external Serial ATA devices for the highest data
transfer rates (6Gb/s), simpler disk drive cabling and easier PC assembly. It doubles

F_USB1~2: Front Panel USB 2.0 headers.
The motherboard has two USB 2.0 headers supporting 4 USB 2.0 ports. Additionally,
some computer cases have USB 2.0 ports at the front of the case. If you have this
kind of case, use auxiliary USB 2.0 connector to connect the front-mounted ports to
the motherboard.
Unlike F_USB2 in this mainboard, F_USB1 supports EZ Charger technology, pro-
vides 3 times current than general USB port in off mode for USB devices. It is useful
and excellent, especially for the iPhone, iPad and iPod touch devices that need a
large amount of current for faster recharging within less time.
