How many watts do I need for my rig?

[Xanthior]

I'm looking into building a computer and am unsure over how many watts the PSU will need to supply for my rig. I have used PSU calculating sites, but the amount varies so I am still unsure.
My future rig specs:
AMD FX 8350
Nvidia GTX 960
HyperX Fury ram 1866mhz
MSI 970 gaming motherboard
Western Digital 1tb 7200rpm hdd

550 watts is enough room to power all of your components If you want some wiggle room for upgrade and overclocking, I would suggest a 650 watt power supply
