What 850W PSU for my build?

[Phauglin]

People tell me that OCZ 750W is not enough for my build so I ask for your help.. I think a decent 850W PSU will do just right. I do live in CZ in Europe so the variety of brands in not optimal. The brands we have here are: Antec, Be Quiet!, CoolerMaster, Corsar, Enermax, Fractal design, Chieftec and Seasonic. I also want the PSU to be modular.

My build:

Msi Z87-G45 mobo
i5 4670k cpu
Gtx 760 sli
16gb VIPER ram
H100i

750W should work, actually. But 850W should be safer.

From experience, Corsair PSU's are fantastic. Realiable and really quiet.

Can't really comment on the others, but I've heard good things about Antec
