the ax1200I should be able to run the neptune without any special bootup procedures right?
Based on what Neptune users have reported thus far, you WILL need special bootup procedures for this PSU. See KnC's troubleshooting guide under the heading "PSU powers off when ASIC boards are connected".
If you haven't bought your PSU yet, get EVGA 1300W Supernova G2, good reports so far. Or Seasonic X-1250.
I understand what you mean
So what about 2 ax1200is for 4 neptune cubes and then run the controller and 5th cube off of another 800 or so watt PSU -- that would work without any special bootup procedures right?(i'm asking this because my friend has spare ax1200s)
