Are you going to be getting a dedicated graphics card for that system?
Also, you have a mobile i7 listed which cannot run in desktop boards, the socket and pin count are quite different. What do you plan to use the system for? Very rarely does someone need more than an i5, unless you are planing to use your desktop as a workstation to do large amounts of video editing or some heavy engineering applications an i5 is more than enough CPU power. Something like the 3750k would be compatible with that board and more than capable.http://www.newegg.com/Product/Product.aspx?Item=N82E16819116504
I would also not choose an intel board, they lack many of the bonus features that boards from companies like Gigabyte and ASUS include. I am not up to speed on the latest Z77 based boards so i will defer to someone else.
As for power consumption, right now your system would consume less than 250 W at full load due to the lack of a GPU, if you intend to include a single powerful GPU a good 500-600 W PSU will be more than sufficient.
