Looking for Low Power BTC Miners

I'm hunting for some BTC miners that don't suck up a ton of power. Ideally, something in the 300-600 watt range. I need them quiet and efficient since I’m limited here in the US. Gonna use 'em to heat up my place during winter, but I need a few more to cover everything. Any suggestions? Oh, and they must work on 110V.

Old ASICs like Antminer S9 use under 1400W but they're not really comparable to newer models like the S19 Pro+. The new ones might use more power but they deliver way more hashrate. If you’re looking for 300-600 watts, good luck mining Bitcoin profitably with that. You might want to stick with GPUs instead.

Yeah, if you're at 300W, less heat means quieter fans and lower costs. But honestly, you won't find anything as efficient as the new gear. The S9 still pulls around 1300W, and you’d be lucky to make a few bucks a month if you run just one hashboard. Worth it? Not sure.

Thought about the S9 too. If I just run it with one board, maybe it'll be good? Efficiency is key but I’m mostly HODLing here. I need to heat my cold basement anyway. So maybe this range of 300-600 watts could be just right for me.

You wanted something to heat your home NOW, not some far-off solution, right? The S9 is okay but it’s more of a node than a miner at 3 TH/s. You’ll be better off just buying coins outright. Running one board drops power to about 400W, so less need for cooling and fans.

Running a few S9j boxes underclocked at about 700W. Custom firmware makes it easier. Not really as profitable as newer miners, but they do the job as space heaters. Using them in shrouds makes it better too.

You could do it, but it might cost a ton. Modern miners hit around 3000W usually. If you run just one hashboard, you can get down to about 600W, but that’s still a stretch for what you're looking for. If you drop two boards, you’ll get closer to 500W but the hashrate will drop.

For something out of the box, consider brands like Heatbit. They use mining chips to generate heat, but they’re pricier than regular heaters. Just a thought.

With electricity costs like that, finding a profitable ASIC for Bitcoin is rough. Maybe look at quieter ASICs for altcoins instead. It's worth exploring options beyond Bitcoin.
