psu needs and wants

[chromebrain]

I'm a gamer who needs enough watts for
Gtx 770
I5 4690k
Asus z97 a
Kingston hyperx fury
Cooler master hyper 212 evo
Western digital 1tb hard drive
LG electronics optical drive
Sli is in my mind as a minor thought as in if I came into the money I would maybe sli my 770's but it might not happen ever
BTW
I do have certain brands I like more than others mostly corsair

Your best bet would be to try out a PSU calculator. Most of them will give you similar results.

This one is my favourite: http://www.bequiet.com/en/psucalculator/expert

A quality 750W is enough, you can go 850W if you want the headroom. Corsair are over priced ATM for the good quality units. XFX & EVGA are good for the same quality, for less. XFX use Seasonic OEM on everything they make & EVGA use Super Flower on their high tier units, like suggested below.
