Agreed, but given that the PSU is in the system to handle peak load, 
having an 800W rather than an 150W PSU, suggests that the PC will be 
expected to consume more power.

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.
