The right PSU for my build

[SargeK155]

Im building a new computer and im not sure which PSU to get. I've read that not only the wattage is important but also the quality. CPU and GPU's are:

CPU: I5 2500k
GPU: Will buy one of the Nvidia Kepler series when they are released

I'm going to be using it for future upgrades as well and i might go SLI with the GPU with the PSU.
I have been looking at both the Corsair GS 800 and the TX 750 V2. Is 750 Watts enough? and are there other good brands for PSU's that dont cost a fortune?

Antec and ocz are also good, but you won't save much. Same for seasonic.

Corsair, XFX, Antec, Seasonic are all good brands. 650+ would be a good start, more for future upgrading purposes.

As you´re planing to overclock, since you´re getting a I5 2500k ("k" means ability to OC) and a SLI config., then get a 850W PSU like CORSAIR Enthusiast Series TX850M 850W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139029

I love my Corsair TX650M. It's modular and plenty of power for any single card, overclocking, and a half a dozen fans. If you know you're going dual cards +1 on the 850w recommendation.

good looks, basically modular(only essentials r attached), silver 80 plus rating(meaning it'hit 90% efficiency quite often and easily stay over 80% efficiency most of the time) and a good wattage for future. comes with every cable sleeved, these cables are VERY long and it comes with a good bag for putting cables u won't use but might in the future.
