15) ATX Power Supply Connector (20-pin block ATXPWR)
This connector connects to an ATX power supply. The plug from the power supply
will only insert in one orientation because of the different hole sizes. Find the
proper orientation and push down firmly making sure that the pins are aligned.
IMPORTANT:
Make sure that your ATX power supply (minimum recommended
wattage: 200 watts; 235W for a fully-configured system) can supply at least 20
amperes on the +5-volt lead and at least 10mA (750mA recommended) on the +5-
volt standby lead (+5VSB). Your system may become unstable/unreliable and may
experience difficulty in powering up if your power supply is inadequate. For Wake-
On-LAN support, your ATX power supply must supply at least 750mA +5VSB.
14) USB Headers (10-1 pin USB2)
If the USB Ports on the back panels are inadequate, a USB header is available
for two additional USB ports. Connect the 10-1 pin ribbon cable from the provided
2-port USB connector set to the midboard 10-1 pin USB header and mount the
USB connector set to an open slot on your chassis.
NOTE: To use this header, make sure that the USBCNR1/USBCNR2 jumpers
(see 3.4 Motherboard Settings) are set to USB Connect.
