This PSU Calculator
included the Titan and K5000. You can enter the system config into that and it will spit you out a recommended PSU wattage. I'd probably plug in 30% capacitor ageing to be on the safe side. I'd imagine you're looking at a ~1000W PSU requirement. Given the fact that you're talking about $10,000 worth of GPU, don't cheap out. 80 Plus Platinum or Gold is recommended. This Enermax Platimax 1000W
is probably the best on the market. (This Seasonic unit
would be a equally suited alternative) Sure, it's expensive, but it's only 2.5% the cost of your GPUs. Think about a gaming PC that might have a $250 GPU and a $60 PSU (on the cheap side)....that's a 25% ratio.Here's a helpful list
of PSU manufacturers and the OEM units they use.
