I'm already running a crossfire setup. The 5770 are recommended to have i think 600 watts to run?

Way more than enough.
The HD5770 consumes ~90W at full load.
Your CPU would be lucky to break 160W.
The rest of your system (RAM, HDDs, fans, etc.) will take around 50W.
You're more than fine, you've got 60A/720W on the 12V rail. I'd be comfortable using TriFire with those cards on that power supply, honestly.

You don't really know anything about PSUs, do you... this is a ridiculous suggestion.

The efficiency of a power supply isn't dependant on its wattage, at all. Neither is its ripple.

Seriously? a 850+ to Xfire two cards that barely take anything from a pci-e connector?I bet i can even crossfire 2 5770 on my supply.
By your logic an Atom based pc should have a 500W+ PSU , am i right?
