5.9 Watts: The World's Most Efficient High-End Computer

From ExtremeTech:

Dutch hardware hacker, Emile Nijssen (nickname Mux), claims he has built the world's most efficient high-end desktop computer: An Intel Core i7-3570K with 16GB of RAM, 64GB SSD, and other assorted bits, that consumes just 5.9 watts when idling and 74.5 watts at full load. Your desktop PC, by comparison, draws around 30 watts while idle and 150 watts at full load (while playing Angry Birds, or surfing a Flash website). Mux has a bit of a history when it comes to ultra-efficient computers: He built a 50-watt computer in 2008 (called Dennis), a 20-watt computer in 2010 (Dennis2), a 9.5-watt NAS last year (Floppy2), and now the 5.9-watt Fluffy2. Fluffy2 is currently just a headless motherboard, but it will eventually be built into an IPS LCD display to create a passively-cooled all-in-one PC that draws less than 20 watts - the most efficient high-end PC in the world.
