You have to read the specs of the power supply. "500W" says nothing about each power rail. Well, not nothing, but nothing useful.
As I understand it, some power supplies have multiple 12V rails. So be sure that you spread the load across those rails. Not that I know how to -- I don't know how you can tell which connectors are on which rail.
There is a belief that cheap PS specs lie and that expensive/good PS specs are conservative. I don't have first-hand experience to say.
Have you measured the voltage of your system under load? Are rails drooping?
You can, of course, put a way-too-big PS in for testing. If things get better, that suggests something was wrong with the old PS, perhaps the capacity.
