OK, so I bought a Tagan 1100w PSU. It has 6 rails, and each one says 20a

My question is this, lets say you have 1 8800 GTX. When I think of rails, I am thinking connectors. In other words.

4 rails = the 4 PCI-E 6 pin's
2 rails = the 2 PCI-E 8 pin's

so that = 6 rails.

if I plug in 1 GTX i assume that I can only tap into 2 rails as the GTX has 2 6 pin connectors. So I see the GTX being able to use a max of 40a. Is this an accurate way of looking at it, or am I looking at this in the wrong way? Can the GTX tap into all 6 rails even though its only connected to 2 of the PCI-E Power connectors?
 
Not necessarily... not all rails mean connectors and vista versa. Some PSUs do allow for rails to be combined in the even that the videocard makes it necessary. Id like to think that the tagan can do this.

Rails don't work that way at all.
