Asus PRO is good mobo. (if you need wifi + bluetooth)
But if you are 100% sure you do not OC then drot mobo price down.

This is good cpu cooler.

a good 450-650w psu is enough for one video card build. If you do plan get SLI then 750-850w is fine choice.
This is really good and now cheap choice.

Modular, Gold efficiency, Five years warranty.. Really good reliability. And with this you can sli two GTX 770..
Must buy is SSD (if you do not have one) cheap and good fast enough SSD is sandisk ultra plus. Take 256GB smaller is too small for video editing. Lots of guys use smaller 32-128GB SSD for cashing. Samsung PRO is fastest but cheaper MLC chips are good too.
Video card needs to be GTX 650Ti boost or faster. New GTX 760 is really good. IMO but you can use GTX 650 and do really good fast video editing. Gaming is wher you'd need video card.
4770k is not best choice to video editing. Intel 3930k or new 4930k are the best. For video editing you need fast cpu. Lots of memory, Fast SSD / HDD and lots of HDD space. So for video editing you need build like this.

Maybe bit overkill cpu cooler for not OC use. This is better one for you.

If you wait two months then new 4930k is coming to store. Maybe best wait.
