First think swap your CPU to i7 4770k. 'k' defines that your CPU is unlocked and is ready to go for overclocking. Since you are buying Z87 mobo which are made for OC (basicly) your CPU should be with 'k' so that you can overclock it in future..
Swap your PSU to a Corshair CX 750 because i beleive that is more quality PSU then that and would give you more future proof ( i mean more wattage ) in case you want to go for overclocking or SLI( which wont be needed with a 780Ti tho) .
Rest good!
