I'll check, but I imagine same rules apply. Don't quite understand why anyone ships with a PSU due to the customs complications this presents in certain countries, especially when they are easily obtainable elsewhere (with enough warning).
It's likely to be something like 2x something chunky wattage wise PSUs. IDK off the top of my head those EVGA 1300W Supernovas should cover all bases with headway in case any additional is required.
Final numbers we can never have at this stage in the game, but headway is good of course. Obv w.r.t. optimisation we want to bring the hashrate up, and the power consumption down , and we are trying our best to achieve that for all of you and do so as expedited as we can safely whilst cautiously respecting this level of tech.
...but please tell me you will at least have room in the case for standard ATX power supplies. The tangle of wires on the outside of the machine is really quite ridiculous. It was understandable on the Jupiters due to the time constraints but there is really no excuse for it on the Neptunes.
