In reviews I have been reading I notice power supplies are efficiency are at the highest when they psu is being closed to maxed out in watts. with a low load the efficiency is less. why is this?

This will always be true due to the power dissipated across the internal power supply circuits. This remains relatively constant, and therefore is a higher percentage of the total power with a lower load.
