New 1 Kilowatt PSU - Too Much Power?

Steve from Hexus writes "While at the GC 2005 gaming convention in Leipzig, Germany, Hexus.net encountered a new 1kW PSU from Enermax, called the 'Galaxy'. At peak output it will use 1.4kW of mains power to provide a total of 66 amps across its various power rails. Who will actually have a need for this PSU, and when this amount of power is being consumed, shouldn't we be thinking about redundant power systems (or perhaps energy efficiency) instead?"
