So I'm getting three of these badboys from my mate very cheap soon since he's upgrading his pc - but Since I've only got a 700W PSU I'd like to know what PSU You suggest me to get to be able to run all three of these. Ideas?

I would recommend getting very high quality 1000w unit atleast. If you want play it safe and allow some headroom AX 1200 would be optimal choice. Had HX 650W for 2x 570s and it was just enough for heavily overclocked i5 2500K + stock cards.

PSUs are most efficient on 50% load so u have to overpower your PSU by 100% to have the most out of it, and it will last u longer, because of the lower operating heat.So if u need 700W get 1500w PSU.
A.F.A.

Wrong. Newer and better PSUs don't have a parabolic curve; it shoots up quite acutely between 20-30% and dies down around 85-90% - between that the efficiency curve is relatively flat, and it doesn't necessarily peak at 50%. In fact, a lot of units nowadays have two peaks at 30-40% and 60-70%.

I bought myself a Fractal Design Tesla R2 1000W. I should proberbly have gone for a 1200W, but I got it quite cheap.
