EDIT: Also BD, I'm not entirely sure but I think you missed something. The MB should draw some watts, too. After all it's something that requires a power connection and heats up to the point it needs cooling (the R4E chipset even has active one).
Consider this without the cold caths a 590 (which pulls more wattage at idle than the 690) and only 1 hdd and 1 SSD I pull 95W at load. NO performance tune. Load is 225W.
