Re: EVGA 680i .....D.O.A.
Wasn't a grounding issue? PSU was plugged in right to the 680i? RAM and all cards pushed in to slot all the way? CMOS battery was in? CPU was mounted right along with the HSF assembly? The Computer Case's reset and power switch buttons were plugged in board properly? Did you try it with 1 stick of RAM at all? Possible ESD, were you grounded when plugging in all your parts?
just some questions and things to try for the future.
