No idea Kwak. I don't post here that much but I think I will start posting in this forum a little more. Oh and as for the people who are talking about "combined" rail amperages, it is a bunch of hooey. Those figures are just trumpet-up, baseless figures that are spewed by the graphics card manufacturers. They don't take into account peak vs continuous power output, rail distribution, OCP limitation etc, etc. I believe that quoting those figures does a great disservice to everyone reading the post.
