Cant decide between an evga 850watt supernova, or a 750watt supernova. I'm not sure which would be needed. My build:

Cpu: Ryzen 7 2700
Mobo: Asus ROG Strix X370-F gaming
Ram: Corsair Vengeance RBG 3000mhz
Gpu: Rtx 2060 or 2070

I have 3 140mm rgb fans, 1 120mm rgb fan, and one WD blue 7500rpm drive. I'm looking to overclock my cpu to 4.2 Ghz and will put a corsair h114i rgb pro as my cpu cooler. What psu size do i need for this build?

Thanks for the input. I've never built one before, my current build was gifted to me and it has an 850 watt OCZ bronze psu i believe, so i wasn't sure what size i should go with. The 850 watt psu in my current build is potentially 6 years old or older as it has an fx 8350 (assuming the psu was bought new with the cpu).
Would it be ok to keep using the 850 watt i already have since it's plenty big but older? Or would it be too big a risk?

You could use it, but I'd start saving for a good replacement. Those old OCZ weren't that great to begin with and now it's 3 years out of warranty. For a 2060/2070 650w is seriously plenty of overhead, if looking at Evga I'd stick with the G2, Seasonic Focus or Corsair RMx are on the same level.
