This is not precisely an aug. It's the effect per piece of "infusible" armor that is at 100% purity when you equip a Pure Energian Elemental Orb in the Power Source slot.
If your armor is at a lower purity the stats increase will be lower.
What's nice is that if you are wearing 7 pieces of infusible armor you get 7x this benefit (while the power source is equipped of course).
Different Power Sources deliver different benefits including some that are negative.
A good site to see the relative effects of Power Sources is:

Be sure to check out the link on the bottom of that page for the "Pure" type.
