1200watt SLi confi... I know that's equivalent with like an air conditioner running. do i have to worry bout my electronic bill?
It has to do with your components. Nothing in existance can use all the power that 1200watt psu can pump out. Power consumption would be only a little more than if you use a 800watt psu. Higher wattage psu tend to be a little less efficient on lower load, thus, the small waste.
