i would like to ask what PSU is best in X-Fire support. Is a 750W PSU enough for X-Firing (HD4870x2)x2?

I wouldn't try it. I'd look at the Enermax Galaxy 1000W or Corsair 1000HX. Incidentally, that's what nVidia certified for 9800GX2 SLI, among others.

Each 4870x2 is rated at 250w each, at 500w for 2 a 750 would be overloaded, even an 850w wouldn't have the headroom. Like aevm said you should go 1000w

A good 600w can handle crossfired HD4850s. 184w for the cards. Even a quality 550w like the Corsair
