Well this will rumble the feathers, I use a 1300w PSU, yes you read that correctly 1300w! That's because I don't run a basic system, 5+ HDD's, 16gb RAM, 4gb 770 GTX and a quad over clocked to 4.3 it needs over a 1000w PSU! Also take into consideration that normally a PSU runs at better efficiency when NOT maxed out, and they run less efficient maxed out. Always wise to add extra watts as this gives you room to add more to the PC and also the PSU capacitors degrade over time. This is where a low spec'd PSU starts to hurt you and your system.
