you are using a z68 board, a chipset that was designed for sandy bridge. it will definitely work with ivy bridge chips (i5 3570k) but then you need a bios update. to update the bios, you need a sandy bridge CPU to get that going. unless you have one, it would be rather pointless to get this board
^ as he said its easier just to get a z77 motherboard and i advice going with a seasonic powersupply over that one.The xfx core and pro seires from what I have been told are manufactured by seasonic so there just as good.personally run a pro semi modular 850w from xfx.
