Hello, I'd like to know what the minimum psu for 2x ati 5870 2gb would be, as I have already bought a 750 watt power supply and I'm not sure as to if that would be enough to handle it.

You need to look at Amperage. What make and model is the PSU?

Consider 18Amps per card and 10-12 for your processor on the 12V rail. A good available 50Amps on this rail will get you there. A corsair 650tx fills the bill nicely.
