In case you do not like the selection above here is a critique of your selection.
Raid 0 really is not worth it for the hdd anymore, it's not that much of a performance jump. The ssd will outmatch anything of the sort with ease, so you can stick with a single higher capacity hdd.
The i7 is not really going to be used unless you are doing video editing or things of the sort, you can stick with the i5 to save some money there.
The H100i is not all that great you should look at some air cooling solutions like the Noctua D-14 performs better than the 100i at a cheaper price point.
The Sabertooth is not all that necessary it hardly does anything but well look rather lame. (Coming from someone who likes the look of circuitry.) That aside you can get the UD5H for less and it will perform a bit better.
1866mhz memory is not all that needed you can save a bit and get 1600mhz ram with the same performance. Kingston ram is not always known for quality so stick to G.Skill or Corsair.
At your price point you really should look at getting a 7970 instead of the 670 because it will perform better at a similar price. It's a great card with a lot of power and can run better at High res.
That's all I can think of as of now.
To anser your question about the PSU it's fine you will get a long lifetime out of that one.
