IC-746 FAQ
Other and future rigs may have greater power demands (like the 756pro). Extra capacity now
may avoid the need to upgrade your supply in the future.
You might well spend most of your time in a low power situation (SSB QRP) and get by with
less than 5A. But, in an emergency, you and your gear may be called upon to operate in

So, you'll find most of us with power supplies ranging from 20 to 30 amps continuous; and
some with even bigger supplies.
