nah i just have a 430w psu. (see member configuration for specs)
lets just pretend that my 4850 consumes all the power(83w) and all other components use nothing. Then we add another 3 4850s so its 83*4=332w. I know my 4850 isn't the most power hungry card in the world but could the most power hungry card really use 3x the power of my 4850? ...hmm that's not a very good way of making my point but it'll do
-my power meter is faulty
-1200W PSUs are useless
-the 4850, 90nm 5600+ and other components are very energy efficient.
