2. ATX Micro-Fit power connectors (24-pin ATXPWR1)
These connectors are for an ATX Micro-Fit power supply. 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.
• Make sure that your ATX 12V power supply can provide 8A on the +12V
lead and at least 1A on the +5-volt standby lead (+5VSB). The minimum
recommended wattage is 230W, or 300W for a fully configured system.
The system can become unstable and might experience difficulty
powering up if the power supply is inadequate.
• You must install a PSU with a higher power rating if you intend to install
additional devices.
3. USB connectors (9-1 pin FRONT_USB2)
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.
Never connect a 1394 cable to the USB connectors. Doing so will damage
the motherboard!
