Also there is gains to be had in running a single vs. dual power supply; however the savings might not be worth the single point of failure. In my quick testing I did not see any difference on my Kill-A-Watt.
Servers and electrical efficiency
I ran across this a while ago and thought it worth a share. In summary running a higher wattage power supply might be costing you a bit of extra money! Aside from the higher purchase price, it turns out that power supplies have a range where they are more efficient. I haven't done a back to back measuring. I am sure using HP ILO's and my Kill-A-Watt the differences are within statistical noise.
