module or two. The one-power-supply model will ship with a metal bracket cover
for the empty bay.

To install a second power supply module:
1. Locate the empty power supply bay on the rear panel covered with a metal
bracket.
2. Loosen the screws that fasten the cover, one on the top and the other on the
rear.
3. Use the screw driver to remove the cover.
4. Insert the second power supply module
Note on the power supply mid-fan
When you re-install the mid-fan for the CPU(s), make sure that the four fans
designed for the CPUs cooling (labeled CPU) are installed in the correct
place. Installing the lower-speed fans for CPU will cause CPU overheating.
