To be honest, I think that a lot of people go for the maxim of 'bigger is better' when it comes to their cpu, I've been running a 400w enermax psu for the last four years or so, and it is still more than able to run my rig quite happilly, now yes, I'm not pushing for the highest overclocks, or the biggest 3dmark score, and my cpu may be at the low end of the spectrum, but it is more than enough for me, in fact, last time I measured it, I was barely pulling 300w total while gaming, so *shrugs*.. it's nice to see good quality at the lower end of the power requirements.
