Before I threw this out with the trash, I thought I would preserve it by scanning it. I've see a lot of questions about the supplementary power connectors for the GTX 200 series. Hopefully this will help with "a picture being worth a thousand words".
This is for the BFG line of GTX 200's, but I'm sure it's applicable to other brands as well.
