Antec CP-850: Unique PSU with Top Performance
 

The CP-850 is 1.2" too tall to fit into all but three of Antec's top cases, so its popularity has to be be unnaturally limited. But the electrical and acoustic performance is superlative, especially in those cases, and it comes at an amazingly low price. White elephant or futuristic visionary?
