When I had my rigs on X11 I noticed about 30% less power usage with under volting. Now, I am not sure if that is inherent to the hashing algorithm, or that mining software is just poorly optimized. That being said, the list power consumption of that rig is 1260 watts. At 30% savings that is 756 watts. Theoretically an 850 watt power supply should be enough. Although you would probably not have enough pci power connectors and would have to use molex converters. If it was me, I would buy a 1500 watt PSU or two 850 watters and jump the second one and be done with it. That way, if you decide to mine a different algorithm, or the miners become better optimized you will be covered. Secondly, there is no substitute for a quality power supply. Go big or go home. Make sure you buy a reputable brand. There is no reason to play Russian roulette with your hardware to save a few bucks on your PSU.
