HardOCP published some more info about the upcoming R600 GPU from ATI. According to information from ATI a single R600 can use up to 300W (+/- 9%) of power while a CrossFire R600 config can use up to 600W (+/- 9%) of power.
This is crazy.
Compare that to a single GeForce 8800 GTX that will pull 150 to 180 watts. Add in a CPU to that mix and you overtake most power supplies’ peak ratings on the retail shelves today.
Also many have been worried about the size of the new R600 video cards. ATI is stating that 345mm / 13.6" will be the required space to fit the cards in a case. (Yes, the retail version will be somewhat shorter, or at least that is what is told to us even though we have yet to see one.) This figure is the card's 335mm physical length plus 10mm to properly install the card. A GeForce 8800 GTX is just under 11 inches longs while the 4 GPU 3dfx Voodoo 5 6000 comes in at 11.75 inches. Certainly if you have an R600, it looks like you will be able to claim having the longest in the room….
