Please ensure that the power (Watts) required by the equipment connected to any power supply is below the power output rating of the power supply used. This will prolong the life of the equipment and that of the power supply. As a rule of thumb your power supply should be able to supply 25% more power than is required by the device/s connected to it for best performance.
