It's not a solid fact either. If Madara used it during his lifetime, then only with EMS. Also, if we accept another assumption that some sort of boost is necessary for PS, then all the boosts shown are either EMS (reinforced MS) or Six Paths chakra. Since Rinnegan is a product of the latter, it's not the thing that allowed to manifest PS, but the SPS itself. Well, it's in case we accept that Kakashi was able to use a PS thanks to the SPC boost, which also isn't a solid fact (some of his jutsu were said to be reinforced by SPC, but not necessary the PS itself), without it, we could came to the conclusion that even a regular MS may suffice.
