I find Mark's point very important. Obtain and use a supply which is
more than adequate for the service or load. Thus a 25 amp supply
feeding a radio drawing 20+ amps will need lots of cooling. This is
not the way to do it. Get a 50 amp supply for a radio drawing 20+ amps
and the fan(s) will likely never come on. Go the cheap way and get
the cheap results. Do it right and be happy. Don't be a cheap ham
and then complain about the product you purchased.
There is more to choosing a power supply than volts and amps. How about
duty cycle? And CCS rated supplies vs. ICAS rated supplies. Humm.......
