The rating on your supply is a max rating the supply will deliver, not what your system will draw. You need to calculate amount of power your system will require, and see if it is less the 150 watts. If your system was running fine with a 160 Watt supply, then 150 Watts will probably be okay. Most engineers allow more than a 10 percent design margin in there products. I suspect that your system draws much less then 160 Watts.

The supply I use is my own design with linear regulators configured as switch mode controllers. Probably the same effeciency as an Inverter/AC supply setup, but it survives engine cranking with no tank circuit or UPS.
