That all looks pretty good, the only thing I'm iffy on is IIRC the Corsair CX series isn't that great of a PSU. It's -ok-, but it's a lower-tier make and for something that connects to everything - should it fail - it could do some damage to your system.
You can get a Seasonic 620w for about $80ish (the M12II, 80+ bronze, 620w, full modular) which would be a much more 'solid' psu. Beyond that, looks pretty good.
