Unless you are operating with two 1150W power supplies at 220V, it may be
necessary to make tradeoffs with respect to which options can be added and
powered with the installed power supplies. Use the following guidelines when
evaluating these tradeoffs:

Comparing processor and hard drive power–two processors draw as
much current as the four hard drives.

Comparing memory and 3.3V-powered PCI/PCI-X Expansion Board
power–each additional 512 MB draws approximately as much current as
one to two PCI/PCI-X boards.

A single 3.3V PCI/PCI-X expansion board draws 25W.

Comparing hard drive and 5V-powered PCI Expansion Board Power–
one PCI expansion board draws as much current as two to five hard
drives.
