Agree, though even at zero load a transformer uses power.fini said:I think what he's saying is that, whilst what you've said is true you are presuming that the PSU is maxed out constantly. Imagine you have a 400W PSU running a 80mm fan and that is it - would it still draw 570W? No, because it would not be trying to supply 400W.
