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.

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.

I wonder if there'll be a hostng option for Neptune. Power being a potential issue, hosting is the obvious solution.

[Phoenix1969]

Re-examining it with my foil hat on....
There's really no way of knowing right now exact power specs. BUT
.....Given the 30% reduction in watts/Gh/s, we should go from 1.1 to about .77 x 3000 Gh/s....
making the Neptune's min @ about 2310 watts minimum. (If only 3Th/s)
Knowing that, I would tend to think it will either be a dedicated 220v device with a custom PSU....
OR   more likely...have more than one ATX PSU powering it.
I'm thinking in reality, it may be closer to 4Th/s(optomistic, I know...)
So... maybe around 3100 watts
and no,  I retract the earlier statement about the apartment question
that's not small enough for any apartment I now of, but it can be done.
My best advice is this.....  
Call an electrician to actually examine your situation after we find out the details of power requirements.
I think it's safe to say that the Neptune is a commercial device, not intended for Johnny's bedroom.

I got you covered

Here's the power supply required for the Neptune:

You guys know of course that every house in north america has 2 phase 110v...so 220v is available at your panel...you would just need an electrician to come and put in a breaker and a dedicated line to the area where the miner is.

I can't see that costing very much, factor in perhaps another $4-500 for this depending on time and the length of the run.
Put in a 220v 20a circuit and you are good to go.

I did this myself for our Chevy Volt level 2 charging station...piece of cake.

[monsieur]

Little bit of tweaking and got my 5 boards at almost 750gh/s

Tweaking details?

[CYPER]

Anyone interested in a way to remove the 24 pin ATX cable  

I made some for myself - you just plug it directly at the back of the PSU and it starts.

The left single one is for EVGA 1300W and the right 2 ones are for Cooler Master V850/V1000 and probably other PSUs that use the same platform:



Good buy unnecessary 24 pin cable

That's 120/240V.  Sure, adding a proper 240V circuit is the sensible way to go for homeowners, but may not be an option for renters, especially in apartments.

For those cases I imagine using multiple power supplies on different circuits with properly-sized extension cords may be an option.  If I were doing that I would try to make sure all of the circuits powering one single miner came off the same leg.

[Jaymax]

Y'all stuck thinking inside the box...

My Jupiter and Upgraded Saturn-Jupiter have been running for weeks with nary a PC PSU in sight.

Clue 1) 12V industrial power supplies are not hard to find
Clue 2) 5V industrial power supplies are not hard to find
Clue 3) alidirect.com
Clue 4) common your grounds!

And for a bonus - power supplies designed for a fixed specific voltage, are WAY cheaper.  I have a separate 12V switch-mode supply for each ASIC module, and they cost about £8 each - and they should easily handle two 'legacy' KnC ASICs each.

Now please carry on as you were.

I sure hope not!  I say give me as much hashing density as one can fit into one standard 4U form factor.  My one biggest wish is they will finally figure out how to integrate/fit the PSU inside the chassis like HashFast and Cointerra, which probably also meant they will need some type of water cooling system.

Hey, that's exactly what I was thinking about too, I guess if they pull a Josh/BFL and it turned out it require 6000+ Watt, they might have to separate into 3 Mini Mini-Rig boxes 

[Henchman24]

Plug one of these into your 30 amp electric dryer outlet.  Bam! Enough power to feed 2 Neptunes!

Sounds interesting, how energy efficiency are these industrial power supplies?   alidirect.com took me to some generic landing page hosted by Bluehost...

I had the option and opportunity to buy a pre-order 10K unit but my gut told me it won't be as lucrative as the Jupiter I have now. Because of the other companies putting out hardware (it's only a matter of time they will), and such a far time in the future KNC indicated shipping times. When a company says they will ship a product in Q1/Q2 that means they have no clue on when they are shipping anything. How can you NOT know when you will ship something within a three month time? If things are that messed up and have to add another 3 months to it then something is wrong.

I am jealous of people getting Jupiters now, I would have loved to grab a couple of those and to tell you the truth have no idea why I didn't order any. I guess my single upgraded Saturn hashing at 560Gh/s will stay on until it dies.


Hey, anyone in the US know how to compute what it cost approx to run this rig? It pulls 650 watts from the wall and I think is at 5-6 amps. I'm just trying to figure out what the electrical cost is. I'm in the Eastern US.

Doh! My bad - aliexpress.com (it's late here)  -  I am in the luxurious position of having unmetered power, so I haven't checked at the wall to see if they meet the claimed efficiency - but then, with power supplies generally, the quoted efficiency is probably only valid within some narrow load range.  It would only be fair to note that the wee internal fans have already crapped out on two of the eight 12V supplies I have running so far; but dropping on a cheap external 12V fan over the chassis grill will not be hard (because the supplies are under-loaded, I haven't bothered with this yet)
