ATX 24-Pin Power Connector: ATX1 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. +3.3V -12V GND PS-ON# GND GND GND Res +5V +5V +5V GND 13 1 24 12 ATX 12V Power Connector: JPW1 21 GND GND This 12V power connector is used to provide power to the CPU. 12V 12V 43 Floppy Disk Drive Connector: FDD1 The mainboard provides a standard floppy disk drive connector that supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types. +3.3V +3.3V GND +5V GND +5V GND PWR OK 5VSB +12V +12V NC IDE Connector: IDE1/IDE2 The mainboard has dual Ultra DMA 66/100 controller that provides PIO mode 0~4, 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. Serial ATA Connectors: SATA1/SATA2 The mainboard provides two high-speed Serial ATA interface ports. These ports support Serial ATA data rates of 150MB/s and are fully compliant with Serial ATA 1.0 specification. Each Serial ATA connector can connect to 1 hard disk device. MSI Reminds You...
