Low wattage BTC ASIC

[IdMineThat]

Trying to find some BTC miners that are reasonably low power.
Ideal range would be 300-600 watts. Something efficient and quiet. I need the lower wattage as we we limited in the US. Looking for something I cohk

I use Asics to heat my home in the winter, but I need a couple more to really provide complete coverage.

Trying to find something that is efficient, quiet, and not break the bank. Does anybody have any suggestions? Also, must run on 110V.

The old ASICs with lower wattage consumes power than the new miners with high wattage. You can read about old miners like Antminer S9. It is generating 14 Th/s with 1372W power consumption. You can not compare it with Antiminer S19 Pro+ Hydro cooling that is generating 191 Th/s with 5252.5 watts. The wattage is higher but lower in comparison with the hashrates generated.

As for the ones with 300-600 watts, no device of this power consumption will be able to mine  bitcoin profitably. GPU might have this lower power consumption, but not ASICs.

Well the two are almost implied as if you're looking for 300W there is less heat to dissipate so less fan spins less noise, also since it's just 10 means less chips so much cheaper  But efficiency, you're not going to get it compared to the new generation, so ..really hard to come with something.

Even the S9 is 1300W so you would need a miner with just one hashboard active, and...that would make you 40 cents a day or $12 a month! Worth it?
An s15 in low power mode, but that's 850W?
Either way no new miner on the market will fit your requirements!

The S9 is something that I considered. My thought was just to try running it with 1 board.

Obviously, I don't just want to burn money, so efficiency does matter, but I'm really just HODLing. I've got to heat my house one way or another, I get to support the network, and maybe some day, my $50 month increase in the electric bill turns into something more. I have a whole bunch of mining stuff that I use to heat my house, but my basement is cold, and I think the wattage range of 300-600 will put me in the Goldilocks zone.

The few things that I've been looking at:

- The S9, likely only running 1 board (I think that's possible) It's very inexpensive, but ancient and inefficient. It would get the job done, but the fan noise is a downside.

- Avalon Nano 3 (Thought about getting a few of these) Seems like they are quiet, and reasonably efficient. Downside of these, it doesn't seem like they quite exist yet, and the purchase process felt a little iffy

- Apollo BTC Pretty similar to the Nano spec wise, but it's a little more expensive. Purchase process seems legit.

Well, you asked for something to heat your house now, not something you might get in March April  
Three are two things I disliked about it, locked on braiins , don't know if you care and their math:

Stretch your cold fist
$0.12/day is all you need
Plug, heat, and earn $0.3 each day

140w that's 3.3khw so it would mean less than 4 cents per kwh, not really US average!

It is legit but that's more a node than a miner, at 3th/s you're best just buying coins now and pay your bills directly with fiat.

- The S9, likely only running 1 board (I think that's possible) It's very inexpensive, but ancient and inefficient. It would get the job done, but the fan noise is a downside.

If you go down to one board you stop having 1300W inside the box and more like 400W, less heat, so no need for that airflow anymore, less fan speed nedeed so less noise.

I've got a few S9j boxes running underclocked at ~700W. It's a standard setting on a number of the custom firmwares out there. (I use Hiveon because it's easy and mostly decent.)

https://hiveon.com/asic/#S9

That shows you some of the prebuilt setups they have.

As people have noted, they are not even REMOTELY as profitable as newer miners: at best, you're looking at 77.3 J/TH vs 22 J/TH (or whatever). That said, they work great as space heaters that pay you a little money.

I'm running a number of the boxes in these shrouds: https://www.cryptocloaks.com/the-future-of-space-heaters-s9-bitcoin-asic/

Next steps are to tear apart 19-series boxes and use Loki hacks to get profitable space heaters that run on 110V: https://pivotalpleb.com/collections/all

Good luck!

It's doable but it would cost a lot, all modern miners (Whatsminer and Antminer) consume roughly 3000w, running them with a single hash board on stock speed gets you down to 1000w, and with some underclocking you get to 600w pretty easily, on Whatsminer you would set your power limit to 1500w, this will allow each board to use nearly 500w, removing two boards gets you down to 500w, if we talking M30s+ 1500w would get you down to roughly 55TH, you take two boards out you end up with 500w and 18-19th.

Using M60 would get you nearly double that hashrate with the same power consumption, the only issue with this approach is you are going to have to pay for the whole miner, i.e the total hashrate, M60 would be roughly 4.5k M30 would be in the 1k range, maybe 1.2k including shipping, so you are going to buy 18TH for 1.2K which is certainly isn't great if you ask me.

If you're looking for something ready to use, there are commercial heater brand such as Heatbit (https://heatbit.com/) which use mining chip to generate heat. While their chip is more efficient than S9, it's still expensive compared with regular heater.

With such electricity consumption, it is difficult to find a profitable ASIC for Bitcoin. Look at this table with ASICs, I would choose a quiet ASIC for other popular altcoins and not stop only at Bitcoin.
