This has been around the track several times, put here it is again:

The power supply schematic that was posted actually originates from here. There is a brief explanation with that particular schematic explaining the theory of operation.

Although it is only a 200 watt early ATX PSU the description of how it actually works is pretty close to how today's ATX PSUs function. Hope that helps a little.
