I'm trying to understand how the PSU options work with the Area-51m. If I choose base model 2060 no matter what I change it to 2080-2070 it still says 180w x2 same for the 2070 model if I try to change it to 2080 still says 240w and 180w only the $$$$$3999 model. Which I certainly don't have had the proper 330w and 180 w adapter listed. Can I buy extra PSU somewhere? I really want dual 330 to be honest.
