How big a PSU is required to run crossfire setup ?

If you were going to run 2 x MSI ATI Radeon HD 5850 Twin FrozR II in x-fire along with a 955 BE, 4 gb ram and the usual trimmings of HDD, Optical drive, and a H50 cooler.

Wouldit be possible to run this off 700W such as OCZ ModXStream Pro 700w Silent ?

Bearing in mind the CPU is going to be OCed. Gfx will likely be run at stock OTB speeds

A Good 650w with four pci-e connectors,

Antec new truepower 650w or XFX pro 650w

To expand slightly on Stulid's answer, the 700W ModXStream would run 2x 5850s, however you'd have to use molex adapters as that PSU only comes with 2x PCIE connectors.

And it only comes with four molex connectors to begin with, so after using said adapters you'd have none left.
