There is a limit to the amount of hardware households can sustain. Neptune in theory is currently the ceiling until another full step down in process node to sub 14nm, as it's power consumption may limit one device per household mains.

I don't know what kind of mains your house has, but mine has 240V coming into a 200A panel.

If I were to commit only half of my house's electric capacity to miners, and if I assume that a Neptune will consume 3kW, I could still run 8 Neptunes at home.

Or are you trying to subtly tell us something we don't know about Neptune's power requirements?  Wink

24000 Watts during the summer.
I hope you live in the Arctic region or you will have serious cooling problems.

Actually I have a purpose-built "miner shed" with two open ends, with air filters and an array of fans on the intake end.  That's where the miners live during the summer months.

I don't think you understand the thermal dynamics of a 24Kw heater lol. The fans might melt, or catch fire, depending on what they're made of. Unless you already run similar equipment, in which case ignore my comment lol.

Well, the fans are all on the intake end, so they don't handle the hot exhaust air.

So far I've only put maybe 5kW in the shed at a time.

Don't know which part of USA you are in, but if you happen to get 25-30C temperatures in the summer I can tell you with 100% certainty that 24kW would not survive in a closed non-air conditioned shed.

Well it's not closed.  It's built wind-tunnel style with the front and rear walls missing.  The front wall is replaced with fans.

No I haven't tested 24kW in it, but 5kW seemed OK.

5kW in the summer.  Now in the wintertime I have the miners in the house to help heat it.

I don't have anywhere near 8 Neptunes on order.  I doubt I'll ever put 24kW in the shed.  The whole talk about 8 Neptunes was just to say that mains power would not limit a house to only 1 Neptune.

W.r.t. Heat I had to share a hotel room with one of the nov boxes on to check it survived the flight. Fell asleep and woke up covered in sweat. I can't imagine what Cyphers house is like right now.

I also spent a night fixing dead boxes in the DC for the hosting on an occasion. October kit only, was a month or two back. In any case aside the monotonous hum. I had to take a break and grab water every hour. Even with aircon in the building it was hot hot hot.

24Kw in summer will just compound the heat...

EDIT: just saw what Bogart wrote as I posted. Most of the US households are not 240V and 200 Amps though.

200A is definitely not typical, that's a lot of power for a home!

This I agree. But 8 is a bit optimistic Wink
Most people don't have 200A service and a shed Wink
I could probably run 2, but would need a very powerful aircon to cool the air 24/7, which would be impractical as I don't have a spare room for them.
I could rent a separate flat just for the miners, but paying rent + electricity would be much more expensive than just hosting them in Sweden/UK.

Then again we know nothing about the final design/specs, so I would not jump to any decisions yet. Plenty of time to make adequate arrangements Wink

Really?  I thought that was pretty standard.

You would probably not believe me, but you would feel cold in the room where the miners are if you wear only a t-shirt. Ambent temp is around 20C, but because the miners are in between 2 open windows on the opposite sides of the block of flats the air draft is quite noticable and it is not even very windy outside. If it is, then it can get really cold  Grin
I actually enjoy the miners as they are somewhat quiet, yet they warm the whole flat very nicely - I can open/close those 2 windows and regulate the temperature as I wish.
Usually they are barely open during the day and fully open during the night as the miners are in the living room, which is only used during the day.

Older smaller houses may have a 100A drop, but almost anything newer than the 90s would have 200A service. Also, everyone has 240v service. Real easy to tell, go check your main breaker.

Depends on the size of the house and how recently it was built--unless custom of course. My recent house had 240 (or 250, cant remember) amp service. 2,800sq/ft with a bajillion gallon pool.

Most houses I've run across are 150-200, built within the last 20ish years.

Regarding heat, I can't imagine Jupiters warming up a room too much unless there was no airflow and it was small, they're fairly efficient. If you want warm, I've got a 40 amps  of scrypt miners heating my house right now lol. With more on the way.

speaking of scrypt miners... and 24k.  I have had over 20k in my shed 24/7 for 2.5 years..  22k most of the time... lots of bug crunching and cigar smoke... they just keep going..

buy good PSU's and keep the clocks down...  41Mh ltc right now.

house is 200amp, as most are .. even many of the old 100 ampers are being upgraded.

I have to disagree.  100 amp service was typical of post-WWII homes of a smaller nature.  I'm pretty sure that split levels built in the late 1950's onward were 200 amp service with two phases between which one would see 230VAC for the oven and clothes dryer.  100 amp service is still put in things like mobile homes but mobile homes aren't houses.  What goes into a small ranch now-a-days is probably 200 amp since electric stoves and clothes dryers are the norm.

They are not two phases. I wish people would stop saying that. It is 240 V single phase. The voltage is measured across the peaks. I have three phase power at my shop, which makes for really cool diagrams and difficult explanations.

The rest is what I said earlier though.

not quite 3/4  .. wired most of the psu's to 220, so that lowers the amps.

Yeah, I'll be doing much better on power costs with a switch to large 240v server power supplies.

I dont think you have to switch.. MOST psu's on the market will take 220 ...  I actually just wired regular 20amp plugs with 220 and plug my psus right in...just dont plug a light or a fan in that plug!!
