More about single rail
  1. Most sub-kilowatt PSU's today do not have multiple rails, regardless what the advertising says.
  2. The link obsidian provided will take you to an excellent explanation of multiple +12 volt rails.

    True multiple +12 volt rails are only found in high end, high wattage power supplies. The others are just "virtual rails". It was a marketing gimmick. There was a big stink about it a few years ago.
