This is a list of the various aspects of PSU, broken down into constituent categories. I don't think this covers everything so let me know what else needs to be added or you have disagreements with how this list is orginised. As they crop up, links to the relevent thread(s) will be added to the list in the appropriate places. That's the plan, anyway!
