Most new HDD's and new PC's (even desktop PC's), have power saving on the

Well monitors on there own use about 200 w and PC's power supplies are 
rated somewhere about 200 watts as well, so you are looking 400 w (not 
considering power saving)

It's also (my opinion) unethical to leave equipment on that uses 
electricity if it's doing nothing; even if you are payingthe bills. Think 
of the environment.
