CrossfireX hd6870 power requirements?

[Virssagòn]

Hi guys,
I wanna buy a new hd6870 to crossfire with it.
But I don't really know my power supply is good enough...
this are my specs:

- i7 2600K @4.6ghz
- windows 7 professional x64bit
- OCZ-agility3 120gb
- WDC WD5000AAKX-083CA1 500gig
- asus p8z68 V-LX
- Cooler Master GX750 ( on the box there is no certification for crossfire)
- 16gig ram 1600mhz
- radeon hd 6870

would it be enough to run a crossfire setup?

Your current power supply should be more than enough.
