Figure a full system power draw of 550w-575w, I'm going to suggest a SeaSonic made (includes Corsair) or Enermax made (includes PC P&C and Sapphire) 750w 80 Plus Gold unit. They have a single 12v rail and are top quality. The reason I do not recommend more is because when you step into this decade you can stay with a single card such as the 280X and not pull any more power (2x 4890 = 380w. 1x 280X = 250w).

Seasonic does not make all of the PSUs for Corsair. I have read a lot of reviews and some models are made to order at other shops in China.

Some are made by ChannelWell, Flextronics, and Chicony as well, but Corsair designs all of them.

And not only that, corsairs warranty is among the best in the buisness. They stand behind there products to end.
