IEEE 1394 Header
Besides one default IEEE 1394
(9-pin FRONT_1394)
port on the I/O panel, there is one
(see p.12
No. 22)
IEEE 1394 header
(FRONT_1394) on this
motherboard. This IEEE 1394
header can
support one IEEE
1394 port.
ATX 12V Power Connector
Please note that it is necessary
(8-pin
ATX12V1)
to connect a power supply with
(see p.12,
No. 3)
ATX 12V plug to this connector.
Failing to do so will cause power
up failure.
SLI/XFIRE Power Connector
It is not necessary to use this
(4-pin
SLI/XFIRE_PWR1)
connector, but please connect it
(see p.12
No. 36)
with a hard disk power connecor
when two graphics cards are
plugged to this motherboard at
the same time.
