Hi all,

Going through several GTX 275 cards on newegg, I noticed many mentioned their Power Connector is "2 x 6 Pin".

Looking at a number of 850W PSUs on newegg, some are "2 x 6Pin, 2 x 6+2Pin", and some are "2 x 6Pin, 2 x 8Pin".

If someone wants to do a 3-Way SLI of cards that require "2x6 Pin", does that mean the PSU needs to have a total of 6 between 6 Pin and 6+2 Pin? If that is the case, how come the majority of the PSUs don't seem to have that many?
