the best pascal card is the one with the best cooling... ( fancy VRMs other OC features have been repeatedly shown to do nothing) with that in mind pretty much any decent 1060 works, as all the cooler has to do is keep the card at its peak boost. the generic EVGA ACX cooler cards should do fine.
as for the PSU, go for a seasonic M12II 520 it is currently very cheap on newegg and is a great PSU for it price. it is also very solid.
