With each successive generation, the power requirement of a typical enthusiast's PC goes up another notch. The emphasis today for processors may be on thermal efficiency but adding more cores to the equation is also equally popular, leading inexorably to an increase in power demands. AMD's quad core 4x4 platform is an extreme example of such a trend and makes power supplies (PSU) of 1KW and greater, a necessity rather than a luxury. Such a scenario is probably more pronounced for the graphics scene, where two GPUs in a system is no longer the cutting edge.
