Corsair HX850W Enough Power?

:hello: Hey everyone.

So I recently sold my ol' Coolermaster Real-Power M700, and brought a Corsair HX850 Power suuply, The main reason was because the old power supply made alot of noise (Coil Whine) which was extremely annoying.

Anyways I plan to go crossfire very soon and would like to make sure that My Corsair HX850 is enough. So below is my system spec's:

Gigabyte GA EX58-UD5
Core i7 920 @ 4Ghz (4.4Ghz for benching) 1.264V
3 x 1GB OCZ Triple Channel RAM @ 1200 7-7-7-21
Gigabyte HD5850's @ 1000/1200 1.225V X2
2 X 10W Pumps
8 Fans
A fan controller
Samsung Spinpoint F3 500GB
Corsair Obsidian 800D
Corsair HX850

Please take into consideration the fairly heavy OC's on the two cards and the core i7 920.

So is a Corsair HX850 Enough?

Thanks in advance.
