The supplier of your equipment should be able to provide detailed information in this area. Here at Crystal Group (www.crystalpc.com) we rollup both power requirements and heat generation information for our rack mount computer systems. We can perform an analysis of a single piece of equipment containing diverse "cards/hard drive/processor" combinations as well as provide a complete roll up for an enclosure/rack of equipment. If anyone would be interested in seeing examples of the tools we utilize to perform this analysis please request via email.
