Proprietary parts are parts that are made specifically for use with that model/company. Dell does it alot too, so basically if you need to get a new part, most of the time you need to get it from them. I guess it's a smart business move but for the customer it's more of a pain than anything. I don't see why a new PSU would fry everything aslong as it's not way over the previous voltage though.
