Which PSU should i take?

[turboto1998]

I am planning to make a gaming build but i do not know what PSU should i take. Here is my build:

ASROCK Z87 EXTREME4
INTEL CORE i5-4670K
KINGSTON 8GB DDR III HyperX (I will buy a second one in future)
GIGABYTE GTX780 (3gb)

I am thinking to buy one of these:
1)COOLER MASTER GX 750W
2)Corsair CX600 80 Plus Bronze 600W

I do not know if 600W would be enough. What do you think? I am also planning to overclock in future. Which PSU will u suggest me to get?

instead of cs600 go for rm650 . it is more than enough with high performance capacitors and fully moduler . . cooler master uses cheap capacitors and not recommended . . go for corsair rm650

600w 42a is the minimum suggested for this gpu. better go with a bigger one.on sli youll need a much strogger. 750w quality one!
