Hello
  Just one minor point I'd like to make.  PSU's are "on demand"
devices.  It is possible, if not common, that a low efficiency 300watt PSU
will average more consumption in the very same machine-environment than a
high efficiency 600watt PSU.  The system will only draw what it needs and
as long as the PSU provides that w/o a lot of losses, the load is
determined by the system, not the PSU.  Therefore, given conscientious PSU
application, we only use power that we actually use in work.  Now if that
"work" is gaming as opposed to weather forcasting or CAD work
that's up to the user-owner and his/her conscience but is not based on how
capable modern systems are, at least, necessarily.
