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 $127 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 1450 W it puts out roughly 4947 BTU an hour. That is a real heater, enough to warm a room on its own, which for a lot of owners 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 70 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?
We do not publish a measured decibel figure for this one, and we are not going to invent one. What we can tell you is that it is a fan cooled desktop unit rather than a datacentre machine, so it is a constant fan hum rather than a roar. If noise is the deciding factor, ask us in the chat and we will get you the real answer from the team rather than a guess.
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 70 TH/s. Running it above that, including any turbo or boost mode, is overclocking: it runs hotter, needs good airflow, and voids the warranty.

Your numbers on this miner
Set your power rate. Pick a coin. Nothing is hidden.
Not sure what you pay? It's on your bill as cents per kWh, or divide the monthly total by the kWh used. If your bill is tiered, use the highest tier you reach: a miner runs around the clock, so its power lands in that top band rather than the cheap baseline one.
Solo pays nothing until you hit a whole block, and then it pays the whole thing. Those odds move with hashrate and difficulty only, so cheaper power never improves them. It only lowers your bill. Pool mining pays small amounts steadily instead.
The PunkHash 70T is a solo Bitcoin miner built around one idea: point real hashrate at your own node and your own address, and keep the whole block reward if you find one. No pool, no cut, no permission.
It focuses on three main things:
- Serious hashrate in one box
- The lowest price per terahash we stock
- Solo mining to your own node
Key Specs
- Model: PunkHash 70T
- Algorithm: SHA-256 (Bitcoin mining)
- Hashrate: ~70 TH/s, plus or minus 5%
- Power Usage: ~1.45 kW
- Efficiency: ~21 J/TH
- Input: 100 to 240V
- Network: Ethernet and WiFi
- Dimensions: 370 x 130 x 380 mm
- Mining mode: Solo, your node and your address
Requirements
- A circuit of its own. At 1.45 kW this draws about 12A on a 120V line, which is the full continuous rating of a standard 15A breaker. Run it on its own circuit with nothing else on the line, or on 240V where the current draw halves.
- Room for the noise and heat. This is a full size machine that happens to live in a house instead of a warehouse. It is not a desk board.

PunkHash 70T vs GekkoScience KBOX
Two very different answers to the same question. The 70T buys the most hashrate per dollar we sell. The KBOX is frugal, quiet enough for a room you sit in, and on the shelf today.
| Spec |  PunkHash 70T
|
 GekkoScience KBOX
|
|---|---|---|
| Price | $1,100 | $800 |
| Hashrate | 70 TH/s | 22 TH/s |
| Price per terahash | $16/TH | $36/TH |
| Power at the wall | ~1450 W | ~330 W |
| Efficiency | ~21 J/TH | ~15 J/TH |
| Circuit | Needs its own | Shares a normal outlet |
| Availability | Q4 2026, from the supplier | In stock |
The KBOX wins most of this table, and it costs less up front. The 70T wins the row that decides it for a lot of people: how much hashrate a dollar buys.
See the GekkoScience KBOX- The cheapest terahash we stock At $1,100 for 70 TH/s this works out to about $16 per terahash. The next cheapest is the Magic Miner 40T at about $19, and most of the small desk boards land between $36 and $45. Nothing else we sell buys more hashrate per dollar.
- Solo, to your own address Point it at your own node and your own payout address. If it finds a block you keep the whole reward. No pool cut, no custodian, no permission. It will also run against an open solo pool if you would rather not run a node.
- Give it a circuit of its own 1.45 kW draws about 12 A on a 120V line, which is the full continuous rating of a standard 15 A breaker. Run it on its own circuit with nothing else on the line, or on 240V where the current draw halves. This is the one thing to plan before it arrives.
- A full size machine, in a house 370 x 130 x 380 mm, wired Ethernet or WiFi, 100 to 240V input. It is not a hobby board and it does not pretend to be. It is a warehouse class machine that happens to live in a spare room.
The cheapest terahash we stock
Price divided by hashrate, across our SHA-256 miners. Lower is better.
| PunkHash 70T | $16/TH | |
|---|---|---|
| Magic Miner 40T | $16/TH | |
| Harlo B30 | $27/TH | |
| Bitfortun BS-4 | ~$33/TH | |
| GekkoScience KBOX | $36/TH | |
| NerdQX | $38/TH | |
| Bitfortun BS-1 | $45/TH |
Efficiency is the other side of this. At about 21 J/TH the 70T uses more power per terahash than the smaller machines, which trade hashrate for frugality. You are buying hashrate per dollar here, not watts per terahash.

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
