I need to know the Power Consumption & Heat Dissipation for the MX7000, Dell Power-edge mx740c,DELL Rack Mountable Workstation 3930 and Data domain DD3300
These datacenter planning tools should get you the information:
I am not aware of a similar utility for client systems. I suggest reviewing the documentation on the 3930 and calculating BTU based on available wattage information.
