   I have some surplus general purpose switching supplies that came with load   
   resistors on the output.  Kind of odd, but one way of making sure it   
   works.  I guess the rest was cheap enough that adding power resistors, and   
   wasting power, was still efficient.   
      
   Of course, PC power supplies have an intended use, an expectation of a   
   certain amount of load, so it makes sense that they wouldn't bother with   
   loading resistors.
