Modern Switch Mode power supplies are up to 90% efficient. Because a power supply is rated at say 400W doesn't mean it will consume 400 watts continuously.In addition the power supply takes a lot power even if the CPU does not need it. Those PSUs are so cheap made that they don't care about reducing power if in idle. Also the losses of the PSUs are quite high (30-40% of max power)
If your setup uses 200 watts, that doesn't mean the other 200 watts are being wasted. It's power handling capacity, not power consumption.

Maybe some CPUs with power saving mode (or using cpuspeed). But the above is dangerous as a general statement. Just as an example: ok, your CPU is idling and not eating power. Is it safe to remove the CPU fan and heatsink from it? After all not "eatting" [sic] power should mean that it isn't generating heat. :-)
So if that's the case then there's no problem with the way it is?
It isn't the case. While CPUs may not draw as much power when idling the higher-end desktop processors from AMD and Intel definitely draw a lot of power and make a lot of heat.
