I have one of these that I want to sell. I got if from a tower that had been stripped of everything else and I have no way of testing it on an actual motherboard. It only has 2 connectors. P1 is an 8-pin and P2 is a 4-pin. I've searched around but it seems like the wiring on these is proprietary, at least not according to the diagrams I've found. I just want to verify that it's working before I sell it. I tested it with the multi-meter and this is what I got.

I don't understand the 11.45v. Does this seem like it's working the way it should?
