First skylake gaming PC build (under 1000)

The power supply is unnecessarily powerful, a 550W-600W would be just fine if you want to save a couple of bucks. Whether to OC or not is just a personal preference. Unlike some people, I'd just go for the non-K since even at stock it will be powerful enough for years to come. So, if you think that you will be able to upgrade in say, five years, then you won't need the OC at any point. Also, if you don't overclock you can settle with a cheaper motherboard and (possibly) just a stock LGA 1150 cooler.
