Connectors - MSI MS-7139 Instruction Manual

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.
ATX 12V Power Connector: JPWR2
This 12V power connector is used to provide power to the CPU.
Floppy Disk Drive Connector: FDD
The mainboard provides a standard floppy disk drive connector that supports 360K,
720K, 1.2M, 1.44M and 2.88M floppy disk types.
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 (8237R/8237R Plus) 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...
Please do not fold the serial ATA cable in a 90-degree angle, which will cause the loss of data
during transmission.
CD-In Connector: CD_IN1
The connector is for CD-ROM audio connector.
SPDIF-Out Connector: JSP1(optional)
This connector is used to connect SPDIF (Sony & Philips Digital
Interconnect Format) interface for digital audio transmission.
