8-pin ATX 12V Power ( PWR2 )
PWR2 , the 8-pin ATX 12V power connection, is used to provide power to the
CPU. Align the pins to the connector and press firmly until seated.
It is strongly recommended that you use an 8-pin ATX 12V power supply;
however, if you have a four-pin power supply, plug the connector to pins 3, 4,
7, and 8 as shown.
Connecting IDE Hard Disk Drives
The IDE connector supports Ultra ATA 133/100/66 IDE hard disk drives.
1. Connect the blue connector (the cable end with a single connector) to the
motherboard.
2. Connect the black connector (the cable with the two closely spaced black
and gray connectors) to the Ultra ATA master device.
3. Connect the gray connector to a slave device.
If you install two hard disk drives, you must configure the second drive as a
slave device by setting its jumper accordingly. Refer to the hard disk
documentation for the jumper settings.
Note: If an ATA-66/100 disk drive and a disk drive using any other IDE transfer
protocol are attached to the same cable, the maximum transfer rate between
the drives may be reduced to that of the slowest drive.
Connect a four-pin
power plug to pins
3, 4, 7, and 8.
