Building new PC (Advise needed!)

My pc is starting to show its age and I'm now planning to build my own pc. I've decided to go for the Core I5 2500K and also a MSI Z77A-GD55 military-class motherboard. I've never built a pc before and don't have too much knowledge about motherboards and other components.

I need some advise if these components are good enough since I am planning to overclock it to around 4.7ghz from 3.3ghz stock.

1) Intel Core I5 2500K Sandy-Bridge.

2) MSI Z77A-GD55 military-class motherboard

3) Arctic Cooling Freezer 7 Pro Rev 2 CPU Cooler

4) Corsair CMPSU-600CX 600watt power supply

5) Patriot Viper "Black Mamba" Generation 3 8GB (2x4GB) DDR3 1600MHz Dual Channel

6) EVGA GeForce GTX 650Ti

Is the motherboard mentioned above compatible with the I5 2500K (Sandybridge) and is 600watt psu enough?

If not good enough what are your suggestions?
