Switching the PSU as you guys said, also the 2nd case will take up less space so I like that aswell.. Came here hoping to just barely get a i5-2500k and 670 leaving with a i5-3750k 670 and better MOBO then I thought, Thanks so much!
GeForce GTX 670 - On your average system the card requires you to have a 500~550 Watt power supply unit.
GeForce GTX 670 2x SLI - On your average system the cards require you to have a 700 Watt power supply unit as minimum.
GeForce GTX 670 3x SLI - On your average system the cards require you to have a 850 Watt power supply unit as minimum.
Remember, if you are going to overclock the GPUs or processor, then we do recommend you purchase something with some more stamina. nVidia itself recommend 500W for a single 670.Since your going to overclock CPU + GPU Add OC to that. http://www.nvidia.in/object/geforce-gtx-670-in.html#pdp...
