That corsair 850w is a good PSU, but I would probably go a little higher if you plan on overclocking everything. Also, I would hold off on a HDD if possible, unless you don't mind paying 2x the price (flooding in Thailand factories is the reason).
the 2600k won't gives you any extra performance get 2500k with low price you will be get same performance of 2600k.and games doesn't require more than 4 cores and 2500k is highly recommend for games or if you are going to do extra tasking like adoble photoshop,autocad or any 3d apps then stay with 2600k because it has hyperthread technology and its good for these type of apps.otherwise 2500k will gives you ultimate performance and other component is excellent.
