The PSU calculators aren't very accurate as they all give be different recommendations. So I was wondering if those with expertise could help me out. Any help would be appreciated. One calculator recommended 383 watts. So I was think somewhere in the 500 range maybe?

Specs

i7-4790K 4.0GHz (4.4GHz turbo)
32gb ddr3 1600 MHz ram
Gigabyte GeForce GTX 1070 G1
2tb hdd
2 120 mm case fans
Msi gaming 5 mobo
coolermaster hyper 212 cpu fan
2 dvd optical drives
1 internal media card reader
1 TP-LINK Archer T9E pci wireless adapter
1 ASUS Xonar 7.1 pci express audio card
 
The calculators run off different assumptions in their calculation methods, Outervision's is the most accurate of the bunch and gets you in the ballpark. I target the system requirement to be in the 50-75% of rated wattage, this is an electrical component sweet spot. You have a K-processor and a aftermarket CPU fan, so I will assume a moderate overclock might be pursued. Based on this assumption I would be looking at 750W PSU.
