Just need feedback or any violent reactions if you have

I don't see why you should be going with 1KW PSU, that's ridiculous. your 5770 and i7 would happily work with 450w PSu Take normal 550w psu if you will CF in near feature, probably the difference between those two PSU's will let you change your Kingston ramm from 1333mhz to 1600mhz ramm, that is better option
Everything els looks good to me

1KW PSU only makes sense un very high-end systems, the ones with 2-3 dual-GPU cards. On a "standard" high-end system with OC and even dual single-gpu cards can work on a 750-850W PSU. To be honest, I would really try to find another supplier if 1KW is the only thing he has ... he is either bad or trying to take advantage of people.

Not, it won't be detrimental in any way. Beside money, the only other "side effect" of having a 1KW PSU could be efficiency; the efficiency of a PSU varies depending on the load and I think most PSU get their peek efficiency between 50-70% load. However, it won't affect either the life expectancy or even the stability of your rig.
