I already have this http://ca.pcpartpicker.com/p/pcgKf7 and I want to do this http://ca.pcpartpicker.com/p/VvDfqs. Simple as that. I've been running off this power supply for almost 4 months now with an overclock to my graphics card no problems. Can my graphics card handle one more though. I game a lot yea.
 
Solution
For Crossfire, you would need to step it up to at least a 650w. You would be putting a heavy load on that 550w and be pushing it. At 650w you would have some headroom, The PSU you have now has 2 x 6+2 pcie connectors and could probably run it, but I think you would be pushing it hard. AMD usually recommends 600w+ for crossfire.
