ATX 24-Pin Power Connector: CONN1
This connector allows you to connect an ATX 24-pin power supply. To
connect the ATX 24-pin power supply, make sure the plug of the power
supply is inserted in the proper orientation and the pins are aligned.
Then push down the power supply firmly into the connector. You may
use the 20-pin ATX power supply as you like. If you'd like to use the
20-pin ATX power supply, please plug your power supply along with pin
1 & pin 13. There is also a foolproof design on pin 11, 12, 23 & 24 to
avoid wrong installation.

Bus Master, and Ultra DMA 66/100 function. You can connect up to four hard disk drives,
CD-ROM, 120MB Floppy and other devices. The first hard drive should always be
connected to IDE1. IDE1 can connect a Master and a Slave drive. You must configure
second hard drive to Slave mode by setting the jumper accordingly.
MSI Reminds You...
If you install two hard disks on one cable, you must configure the second drive to Slave mode by
setting its jumper. Refer to the hard disk documentation supplied by hard disk vendors for jumper
setting instructions.

1.0 specifications. Each Serial ATA connector can connect to 1 hard disk device.
MSI Reminds You...
Please do not fold the serial ATA cable in a 90-degree angle, which will cause the loss of data
during transmission.
