So far, my build is:
i3-6100
ASRock Fatal1ty Z170 Gaming K4 ATX LGA1151
G.Skill Ripjaws V Series 2x4GB DDR4-2400
GTX 1060 6GB
Raidmax Viper II Mid Tower case
The recommended wattage is 246W on PCPartPicker, and I was looking at a couple different PSUs, I was thinking between Corsair CX600, Rosewill ARC 450, Rosewill Glacier 500M, and Corsair CX450M. I was thinking about the CX600 because it has the best reviews, but it has higher wattage than recommended (1.6 of 250 is 400). Well they all are, but it's a lot higher haha, anyway, which one should I go with for my build?
Edit: I am also planning on overclocking CPU
