To be fair most PSU of this size are labeled for multi GPUs. In fact if you look at all of EVGA's PSU's in this size in the 1300-1600 range, they will be labeled for 6-9 GPUs. This just happens to come in a mining box I guess? Personally I'd go hop on EVGA's wait list, or a authorized retailer for any of these any ways if I was in the market. Third party sellers can be a risk / hassle.
