what percentage KO ration should you have to be considered a POWER puncher

[Street]

I would say around 75% or better. Pacquiao has a 60.32%. Juan Manuel hits harder with a 62.5%. Floyd has a 56.52%. If you are a statistical observer, then Mayweather, Pacquiao and Marquez are in the same level speaking bout KO power.

A KO ratio should be based purely on a fighters WINS boxrec however does it with the losses and draws included. Anyway anyone above 75% should be considered a power puncher as it's pretty bloody impressive.
