It's true that a good power supply does make a difference compared to a cheaper one. The idea is to NEVER have the load less than 20% of the power supplies rating, or more than 90% of its rating under any circumstances. That's a pretty wide margin. If you are planning on expanding that PC in the future (ie, add another hard drive, upgrade any component in there that may draw more power), than a 400watt would do nicely.
The rig you discussed would work with a high quality 350, but with NO margin (until you decided to add another HD or something ) possibly. Just a thought...
