The power supply should be installed in the back of the chassis. This is to draw the air out of the inside of the case. Check the position of the power supply as shown.
Using the screwdriver, gently tighten the three screws. This completes the installation for the power supply fan.
Connecting the power supply
After you have installed the system board into the case, you should connect the power cable from the case power supply unit to the system board power connector. Since the storage bay is situated closely to the power supply, remove the screw that holds the storage bay drive for convenience.
Push the storage bay sideways as shown.
Locate the system board power connector. See figure for reference.
The power connector should fit perfectly in the slot on the system board. Note the orientation of the cables before trying to connect them. Each function of the cable is already defined.
Connect the +12V power connector. Make sure the power connectors are properly seated and firmly attached.
Push back the storage bay to its original position. Make sure that the screw holes of the mounting box are aligned with that of the drive and the brackets are smoothly attached to the hook.
The storage bay should slide easily back to place.
Secure the chassis and the storage bay with screws. Do not over tighten the screws. Gentle pressure is enough.
