Personally the ENERMAX Platimax EPM850EWT would be enough for all my present and future needs. Unless you are putting a crazy amount of video cards into your system (yeah, I'm talking about you Vega!) its enough AND comfortable overkill for anything most users could need.
I'll put anything from Enermax at my side .. and specifically .. I'd fer darn sure put an Enermax ECA3290A
COENUS Case with an Enermax TRIATHLOR ETA650AWT-M PSU in it to house and run my my gear!!
