Hey guys, I decided to upgrade my PC this year for the holidays, and I purchased a SeaSonic M12II 620W PSU a couple days ago. The problem is that I've been eyeing the Asus R9 280x and was about to pull the trigger when I saw that it has a recommended PSU Wattage of around 700W. Would I be able to use the 280x with my SeaSonic PSU? Or should I return it for one with a higher wattage? Here's a link to my build if you need it:

All help is appreciated, thanks a lot!
