Best Power Supply Unit for me?

[AnimeDegen]

Hey guys so I'm very new at building PC's (actually this is gonna be my first time). I have everything chosen and bought except for one thing: the PSU. I have used a couple of calculators and they say 500 watt but I'm still unsure. See, I've heard what could happen if you don't chose a proper PSU and it honestly scares me. So if you guys don't mind would you lend me a hand and recommend me a PSU based on my computer, and if it isn't any trouble I would also like to know why you recommended it. This is the list of what I've bought for my computer:

Intel Core i5-6600K 3.5GHz Quad-Core Processor
Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Asus Z170-A ATX LGA1151 Motherboard
Kingston HyperX Fury Black 16GB (2 x 8GB) DDR4-2133 Memory
Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
MSI GeForce GTX 970 4GB Twin Frozr V Video Card
NZXT Phantom (White) ATX Full Tower Case (Has 1 200mm fan and 3 120mm fans)
Will run Windows 10
Acer H236HLbid 23.0" 60Hz Monitor

What do you guys think???
