Hi everybody, so let's start with the fact that I am using a XFX 550W Pro Core Edition as my PSU. I have been using it with these specs without (I think so) problems:

i3-3220
MSI R9 390
8GB DDR3 ram
ASRock B75 pro3-m
1000gb seagate barracuda

But it's time for an upgrade and I was wondering, will my PSU be enough for these specs:

i7-6700k
MSI R9 390
16gb DDR4 ram
MSI Z170 SLI PLUS
1000gb seagate barracuda
