Recommend PSU for dual xeon & 3 780ti

[panda_uk]

Hi can anyone recommend a PSU that could handle dual xeons and 3 780ti's.
Currently I have a corsair 1000w powering the xeons and 2 780ti's but I don't think it could cope with the third GPU.

I was looking at the Superflower 1600w Gold, would that be too much?

Any advice?

Cool thanks, I'll think I'll take a look at the 1300w EVGA and Superflower. Though for ease I might get the Corsair HX1200i so I don't have to redo the cabling.

I did try a PSU calculator and it said 1000w was ok but I feel that it would be best to have a little more headroom.
