It'll need one hell of a big one. My Kenwood TS480 running 200W draws 41A.
In regards to the difference between the 350W of the Magnum and the 200W of the Galaxy, it is half a S point to the receiving station. You have to decide whether all the cost and hassle of the extra power is worth it as you could be looking at replacing/redoing absolutely everything except the antenna. If there's any weaknesses at all especially in the antenna install, 350W will show it up.
