FAQ
Will it pay for itself?
Honestly, at most home power rates the mining does not cover the electricity, and that is not why people buy these. At 12 cents a kWh this one draws about $57 a month. What you are buying is a real, repeating shot at a whole block, plus coin that is yours from the moment it is mined. If your power is cheap or you run solar the maths gets much friendlier. Set your own rate in the calculator on this page and it will show you exactly where you land.
Will it heat my room?
Almost everything it draws comes back out as heat, so at 650 W it puts out roughly 2218 BTU an hour. That is about what a small space heater gives you on a low setting, and for a lot of owners that is half the point. In winter it is warmth you were going to pay for anyway. In summer, put it somewhere you are not trying to cool.
Solo or pool, what is the difference?
Solo means this unit draws for the entire block reward on its own. You get nothing until you hit one, and then you get all of it. Pool means you join your 40 TH/s to everyone else's and take a small, steady share instead. It does both, you pick in the dashboard, and your solo odds move with hashrate and difficulty only. Cheaper power never improves them, it only lowers your bill.
How loud is it, really?
It is rated at about 50 dB, roughly a desk fan or a quiet dishwasher across a room. You will hear it, and you can talk over it. Being straight with you: that is the manufacturer's rating, not a measurement we took ourselves, and rooms differ. If it has to share a bedroom, put it on the far side and run it in its quietest mode.
Can I overclock or turn it down?
Turning it down is easy and a lot of owners run that way overnight, where it uses less power and makes less noise. This unit is rated at 40 TH/s. Running it above that, including any turbo or boost mode, is overclocking: it runs hotter, needs good airflow, and voids the warranty.

Pick how hard it runs from the dashboard. Eco sips power overnight and Standard is the rated 40 TH/s it ships in. Turbo pushes it to 50 TH/s, which is overclocking: it runs hotter, can shut down in a small room with poor airflow, and voids the warranty.

Love them, got 3 in, easy assembly, had them all hooked up and mining, in about 15 minutes, had to find my screwdriver. I have them mining on 2 different pools, trying to compare them. The pools I am on $1.50 to $2.00 a month. Hooked them to a solar generator to save on electricity. Very quiet. That is seven miners in the room, 5 are from Helium Deploy. 2 more on the way. Shipping was a little slow, but I think worth the wait.

I've been running three 1.8 Th miners and I'm very satisfied. The hashrate stays stable at the promised 1.8 TH/s and the chip temperatures remain around 50 °C under continuous operation, impressive for the compact size. The units are also delivered with individual 50 W Mean Well power supplies, which makes installation simple and stable from the start.

The Nerdqaxe Rev 6 was impressive. Came with a Meanwell PSU. The miner with a new 3D printed Base, a shroud that directs cooling to the vrm's, an additional fan for the rear to divert more heat away from the unit. I just set it up, out of box already hashing about 6.2 without tweaking anything myself. I have more enroute to me and plan on buying other units as well.

It came on overclock mode and was making alot of noise, but i fixed the settings to normal and now its Supra Silent... It has never managed to get a block rejected which is impressive after 300K+ shares. It was very easy to set up!🧙♀️

Being that this is only advertised at 10 terahesh. It's turning consistently 11.5 to 12 tH Straight Out of the Box without any tuning or modification. It just plugs away and I'm hoping to be able to turn up some power and tweak it a bit to get some more efficiency out of it
