Power Supply Questions.

Looking to do some small upgrading here soon and was wandering if upgrading the power supply would do any good.
Its never ran nearly as great as i know it should. FS2002 only runs decently with most settings just under medium :-/ And thats using AI models
Its running on a 250w supply. Would upgrading to say, a 450w do some justice to the problem? And would the computer handle it? Or would upgrading it have little or no effect?
