Yes, it is a bit more complicated an issue than I may have made it out to be 
but I didn't want to overwhelm the person asking the question with too many 
details. There are websites online that let you estimate the power 
consumption of a computer based on what is inside the box. Even those can be 
based more on typical values for different items rather and may still not 
represent the actual power requirements for the items in ones own computer case.
