43" Vizio 4k (1080p for gaming)
3 - 27" AOC 1080p

I currently have all 3 27" AOCs running off of the 970 by itself. I want to use my 43" Vizio as my main gaming monitor off of the 970, and run the 3 AOCs off of the 660. My current PSU does not have enough pcie power cables for both GPU's. I also plan on overclocking the 6300, for no reason really, just have never tried overclocking before.

Looking for advice on the wattage I should get and/or suggestions. I am a fan of Corsair but willing to try a different brand if it is better or more cost effective. I want to stay below or close to $130 USD and I'd like to stay with modular or semi-modular.
