Folks seem to be assuming that a Neptune will need to be plugged into a single power outlet.
Depending on the setup, it may be possible to use 2 to 3 1200 to 1500 Watt power supplies plugged into outlets on different breakers to power 1 Neptune...
It's standard to have a couple of 240V, 32A circuits in UK houses. So that's over 7kW per circuit. The master fuse on the grid side of my meter is 110A but I'm not sure if that's at 240V or part of a drop down transformer. I have 3x 30A circuits - one just for the cooker, which I can hack into if needed and 2x for all the wall power sockets in every room. That is 14400W for all power sockets without any safety margins. But I would never consider running more than 1 Neptune at home. I will most probably host them. Or rent a flat as it might be cheaper  Talking of electricity, how much are your miners costing a month? I am dreading getting my first electricity bill. 3.7TH/s @ £350 a month. |

The grue lurks in the darkest places of the earth. Its favorite diet is adventurers, but its insatiable appetite is tempered by its fear of light. No grue has ever been seen by the light of day, and few have survived its fearsome jaws to tell the tale.

Talking of hosting. In Europe, colocentre.nl is the cheapest place I've come across so far.
Outskirts of Rotterdam, they'll host based on the likely KWh draw you need. So far it comes out much cheaper than UK hosting places I've looked into.

You will need 240V and calculate at least 13A at 240V for each Neptune. So UK houses/flats should be okay they'll just maybe need to use different circuits if they have a lot of Neptunes. US homes usually have one 240V socket IIRC but I'm not sure what the amperage is for the socket. No need to worry. Fubly is from Europe (look at the street name at the picture) - there is 230 V. |

You wired homes in the USA and you call 240 single phase "two phase"  We can just let that go though, as this thread is turning into pages of hypothetical power supply discussion. How boring! None of us know what power supply requirements are going to be for these neptunes. What is the speculation for? Total blind guesses. Not really blind, you can figure it based on the efficiency of the chip and the hash power, and then reverse the math for the power requirements. A lot of what's being mentioned is super close. The 3TH was the upper limit for most "home based" mining systems, figured on power capabilities of most homes. KNC said they're being designed to hash more, provided you can give them more juice. This was discussed like 10 or 20 pages ago, with really good numbers. IIRC they were saying 1750-2100watts for the 3TH, but that's just going off of memory. I know the number was high enough that most US folks would require a single circuit (20amp / 12ga wiring, with nothing else on it) per Neptune, unless using strictly 240v which is going to require an extra panel for most people who aren't willing to lose things like their ovens and whatnot. |

Is it normal for the blue ASIC power supply clip (white clip from PSU to blue cable) to get hot? The other cables aren't really hot or hot at all, but this clip is quite warm although I can still hold onto it for a while without having to remove my fingers due to the heat?

ack probably not..i'm just guessing others? you could just run the cable directly from power supply and bypass that blue cable right? see if that helps...assumine it is long enough... if i remember right just elimitate it from the chain of cable? again just guessing here as a hedge others on here should know more |
Old Style Legacy Plug & Play BBS System. Get it from www.synchro.net. Updated 1/1/2021. It also works with Windows 10 and likely 11 and allows 16 bit DOS game doors on the same Win 10 Machine in Multi-Node! Five Minute Install! Look it over it uninstalls just as fast, if you simply want to look it over. Freeware! Full BBS System! It is a frigging hoot!:) |

I think maybe I should try my other PSU? Just my experience with my jupiter, if the cables feel warn especially on the connectors, then keep an eye on it. I feel the cables ever few hours when at home. If you smell anything like a burnt smell check the cables on both the connectors and the PSU. My smoke detector didn't go off when it caught fire. Just can't be too careful. Good luck. |

Try closing the barrels a bit so they are more snug on the pins of the mating clip. If some, say 2 of the 4, are loose and not making good contact then the other 2 will be carrying more current and that could cause excessive heat. |
