6. ATX power connectors (24-pin ATXPWR, 4-pin ATX12V)
These connectors are for ATX power supply plugs. The plugs from
the power supply are designed to fit these connectors in only one
orientation. Find the proper orientation and push down firmly until the
connectors completely fit.
Never connect a 1394 cable to the USB connectors. Doing so will
damage the motherboard!
5. USB connectors (10-1 pin USB56, USB78)
These connectors are for USB 2.0 ports. Connect the USB/GAME
module cable to any of these connectors, then install the module to a
slot opening at the back of the system chassis. These USB connectors
comply with USB 2.0 specification that supports up to 480 Mbps
connection speed.
The USB module is purchased separately.
