Power Supply; Atx 24-Pin Power Connector: Atx1; Atx 12V Power Connector: Jpw1; Floppy Disk Drive Connector: Fdd1 - MSI MS-7143 Instruction Manual

Memory
The mainboard provides two 184-pin unbuffered DDR333 / DDR400 DDR SDRAM, and supports
the memory size up to 2GB. To operate properly, at least one DIMM module must be installed.
(For the updated supporting memory modules, please visit
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_trp_list.php)
Install at least one DIMM module on the slots. Memory modules can be installed on the slots in
any order. You can install either single- or double-sided modules to meet your own needs.
Installing DDR Modules
1. The DDR DIMM has only one notch on the center of module. The module will only fit in the
right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the socket.
3. The plastic clip at each side of the DIMM slot will automatically close.

Power Supply

The mainboard supports ATX power supply for the power system. Before inserting the power
supply connector, always make sure that all components are installed properly to ensure that no
damage will be caused. A 300W or above power supply is suggested.

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 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 (refer to the image at the right
hand). There is also a foolproof design on pin 11, 12, 23 & 24 to
avoid wrong installation.

ATX 12V Power Connector: JPW1

This 12V power connector is used to provide power to the CPU.

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.
