First of all Don't get the 965, it will bottlneck your GPUs big time. FX 8350 or I5-3570k would be your best choice.
Get a bigger harddrive, that is suicide, building a great gaming rig with no space for all the games? Just no.http://pcpartpicker.com/part/xfx-power-supply-p11050befx
This PSU should do fine for your needs.
If I were to give you any advice then I would cut one of the GPUs and have more money for better harddrive, CPU, case, MOBO and RAM. That gaming rig is way too unbalanced. By doing that you would also save some money on the PSU.
