Well, the internet appears pretty lukewarm on that PSU. Some fan problems in particular are mentioned often. Personally I'm not a huge fan of the Thermaltake brand, but that's just because I have other brands that I like more. I would look around a bit and see what else you can find. But if you're set on it, it's not a bad choice as long as you save the receipt.
The rest of your system looks fine. 600W should be plenty of power since you're not overclocking.
