No, PSUs are not CPU specific. Manufacturer's just put it on there to entice people.
Never get cheap on a PSU, if it frys you could fry your whole system.
I'd go OCZ ZS 750W
, or if you can swing it the Corsair TX750 V2
You can actually run your system on a smaller power supply (~500W), but I'm assuming you want headroom for possible SLi?
