My First Build

Solution
Corsair hx 650 is my personal favorite. Seasonic G- series 550 watt is good but cheaper. and i hear the xfx 550 is good to, although i have never tried it myself.
Yes, it's all compatible, and that's a good build.

I assume you're planning on overclocking from the K CPU, the motherboard, and the cooler. So I'll just mention, it's not necessary to overclock the i5-4670 for any games now, or in the foreseeable future. If you're just trying to hold 1080p/60fps you could easily cut costs and leave Broadwell as a possibility by switching to an H97 board, i5-4670, and dropping the cooler.

I would do what he said and then but a better power supply with the extra cash while the cx 500 is sufficient there are better choices that give more efficient cleaner power.
