Compatability/Suggestions for New Build? (I have specs)

Hey guys, this will be my first homebuilt computer and am looking for advice. This is going to be a gaming computer and just wanted to know if all my parts that i have chosen so far will work together and/or if i should change or upgrade anything.

These are my current specs.

Motherboard - ASRock Extreme 4 http://www.microcenter.com/product/387554/Z77_Extreme4_...

Moniter - ASUS Glossy Black 23" 1080p LCD Monitor http://www.newegg.com/Product/Product.aspx?Item=N82E168...

CPU - Intel i7 3770k Quad Core 3.5 GHz http://www.microcenter.com/product/388575/Core_i7_3770K...

Video Card - Radeon Sapphire HD 7970 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Power Supply - Corsair HX - 650W http://www.newegg.com/Product/Product.aspx?Item=N82E168...


These are the items I have picked and believe it comes out to arond $1150, though I have changed some things since the time I calculated that. Since this is my first build I would like to know if all of these parts work together and if any of you have better suggestions for something. I really dont know what to look for in a case but I had somebody help me pick this out, opinions on it?

Case - Zalman Z11 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Other than that do you think I need to upgrade my Power Supply or will what I have picked out do me just fine?

Thanks everybody for your time.
