That was true before we got switching power supplies. These days it is way more complicated than that.
(Bigger heatsinks and beefier components certainly don't hurt. Granted, there are a few other factors, including efficiency if you're paying for your own power these days and it's for a 24/7 box.)
Wish it was that simple. These days there are questions of using the right number of caps for filterting and in the right places and the right types, and how well distributed the voltage rails are in terms of current at each voltage. -- Len Sorensen
