That is what GPU-z says, but not real power...
of course real power is more. just something to compare. i saw my plug on the wall and could also see the raises in watt. from 320 it even reached 400. its better than nothing. dont like it? dont see it
my power meter on the wall confirmed that the lowest power usage come from 480LowEnergyOK.rom while maintaining 29mhash
GPUz reports the power used by the graphics chip itself. A watt meter is able to report the power (delta) of the whole card: graphics chip, memory chips, VRMs, etc.
Each memory chip probably consumes about 5W of power or so. These cards probably have 8 or 16 chips on them.
