Maybe posting this in the Power Supply forum might be a great thing. There are some real good guru's there to help ya.

...or you could use Google. It's your friend.

From the Hardocp crossfire review

For this complete CrossFire experience, ATI is recommending a good 475 watt power supply.

LOL... I wouldn't use a 450 Watt P/S for an 850 Crossfire setup. Maybe if you only had 1 hard drive and 1 optical drive. If you're like most on here you've got a bunch of crap powered up on your PC... and the 850s are VERY power hungry cards. I was actually reaching the limits of my 480 Watt Antec Neo Modular P/S with a single 850 and all the other crap. Personally for me now... it's 600 watts or bust. Oh.. make sure it's a good supply. Doesn't need to cost you a fortune... but needs to be a good supply.

A good 475 watt psu should be fine.
