well to work out your power supply wattage you can use this calculator http://www.thermaltake.outervision.com/
the memory depends on what exactly the computer is for but in general 8gb ddr3 by a reputable brand, if you download the manual from here http://www.gigabyte.com/products/product-page.aspx?pid=4483#manual you will see a qualified vendors list of all the tested and compatible ram with the motherboard,
one thing to be careful of the cpu and motherboard you listed are not compatible, the motherboard is socket 1150 and the cpu socket 1155, you would need to get the i7 4770k for that motherboard
