For our 5x 280x rigs, here are our power numbers:
At stock volts (1.13), our rig pulled ~1450W. After undervolting (1.01), we pulled ~1250W.
You don't need a 1600W. You can get away with a 1500W. We use 2x 750W Rosewill Capstone, and they work wonderfully.
Two smaller PSUs are usually cheaper than one large one; We got our two for $100/each.
