Power Supply - MSI MS-7139 Instruction Manual

Installing AMD Athlon64 / Athlon64 FX / Athlon64 X2 / Sempron CPU
Cooler Set
When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached
on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your
dealer to purchase and install them before turning on the computer.
1. Detach the shield of the backplate's plaster.
2. Turn over the mainboard, and install the backplate to the proper position.
3. Turn over the mainboard again and place the mainboard on the flat surface. Locate the
two screw holes of the mainboard.
4. Align the retention mechanism and the backplate. Fix the retention mechanism and the
backplate with two screws.
5. Position the cooling set onto the retention mechanism. Hook one end of the clip to hook
first.
6. Press down the other end of the clip to fasten the cooling set on the top of the retention
mechanism.
7. Locate the Fix Lever, Safety Hook and the Fixed Bolt. Lift up the intensive fixed lever.
8. Fasten down the lever.
9. Make sure the safety hook completely clasps the fixed bolt of the retention mechanism.
MSI Reminds You...
While disconnecting the Safety Hook from the fixed bolt, it is necessary to keep an eye on your
fingers, because once the Safety Hook is disconnected from the fixed bolt, the fixed lever will
spring back instantly.
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

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.
