It's an additive strength buff, so it doesn't matter how much power strength you have - this buff will always add 50% (+50%) to your power strength. (Whether you have 100% or 200% power strength, the buff from this mod will give +50%, taking you to 150% or 250%)

If you mean like a cap on total power strength like there is for energy efficiency, I don't believe there is a cap.
