The best time to ask questions is BEFORE you buy, not after.
That way, you can change if you need to.
I might have suggested a different psu.
Your psu is a tier 4 unit(Not Recommend for stressful situations. May not be able to put out full rated power above room temperature, and may slightly fail to meet ATX specs) on this list.http://www.eggxpert.com/forums/thread/323050.aspx
But, you are likely to be OK.
