suggestion on your vid card...save some money on the 560ti, and go with the 560. the 560 has every bit of OC potential, and with msi afterburner, you can tune it to around the 900MHz speed every time. Mine is running stable at 950MHz, and not even breaking a sweat. Everything else looks good, and like ervinelim said, both those psu's should be great additions. i would prefer to see you choose corsair, but ocz is a great company too.
ps - nice processor ervinelim!

Corsair HX750 80 PLUS Silver Certified
i do like antec, but i would be fishy of any power supply that adds the adjective "green" to their product. Energy efficiency should be regulated by their Bronze, Silver, Gold Certifications imo. Just like any other consumer product out there, Green is a marketing ploy to attract uneducated people to buy their crap.
Again, antec is a GREAT psu manufacturer, so don't let me dissuade you. I think you could go with a better CERTIFICATION though if money isn't as much as an issue, and get either an antec, corsair, ocz, or even a brand like xfx or silverstone.
The original (80+) EA-650 was only good but not great, but this is the new 80+ bronze one, and is better. I'd use one without hesitation, or the Seasonic jet-21 linked.
If you want quiet, you'll spend a little more, but an 80+ gold Seasonic X-560 does not run its fan on low-moderate loads. It also has modular cabling, which is nice. That is what I have, powering a GTX560Ti myself (click into my profile for the full specs if you care).
If I am not mistaken, some corsair psu's (cx & gs) is built by delta or cwt, but the corsair golds are based on the seasonic golds. Cwt & delta both have good and crappy psu's. So I cannot recomened it as a whole but some are a bit good. Like the chieftec nitro 750, it was reviewed here at toms and it was ok, it was made by cwt. As for corsair i would say from lowest to highest would be ... Cx, gs, tx, hx & ax. I would still suggest seasonics, i have 4 of them and the are rock solid
