Hi, I'm trying to source power supplies for Prusa i3 kits. It seems as though it's a choice between a 12V supply that would need a mains plug wiring to it, or an ATX, which needs some additional wiring to short out the 24 pin connector. What I want to know is - are there any plug and play, off the shelf power solutions available anywhere? It would be great to be able to bulk buy some power supplies and not have to worry about having to modify them for use in RepRaps (or leaving it up to the buyer of the kit to modify).
