How much power is Neptune slated to pull?  Is it beyond anything a typical US household/apartment AC outlet could feed?
I think it will be like this:
If you connect the Neptune  to it's OWN 20amp circuit, with nothing else, you should be fine.
Whatever you do, don't put it on the same circuit as something like a microwave, or toaster, or anything that draws significant wattage. Make sure it's on a 20amp breaker minimum.

When you estimate a 20A circuit, you mean on a 110V line, yes? European 230V @ 16A would give 3680W, which should probably hold if kendog77's estimate of 3000W power draw is anywhere near what we will get.
I really hope that it will draw less than 3000W to be able to have it along other things on a slightly loaded circuit.
Assuming it will be powered by ATX PSUs, the max spec for North America would be 1300W per PSU. Yes, there are 1500W supplies, but 120V/15A circuits must (electrical code) be derated by 20% for continuous use. So 120V x 15A x 80% is 1440W at the wall. A 90% efficient PSU supplying 1300W DC would be right at the limit. If we use 2 of these, we can supply 2600W DC at most.

So drawing less than 2600W DC would be ideal. Otherwise North American people without convenient access to 240V lines would be ... inconvenienced. Sad

I myself would have to find a 240V line to run that machine unless i can get two 1500W PSUs to run it. Even then i am going to have a huge issue with my power being in an apartment

im hoping knc can pull of some magic like when they stated 850 watts for jupiter, but with the firmware updated it was more around 550..... so maybe 1700 watts?! lol

i seriously hope i can run this machine off one 110v 15 amp circuit or it will be a major pain in the ass for me.

OR split the neptune into two seperate boxes so they can run independently off two diff plugs.
