as you see, those are opinions
the recomended psu remains the same for the reason i explained, a 75 watts extra connector will not be used fully, perhaps only 15 or 20 watts more, so the psu will remain recomended as 500 watts, because gpu + cpu and other parts will not use over 400 watts under load so there is space to add more devices or space for overcloking, as i mentioned overprovisioning
