Key takeaways
- ✓ 600 TH/s at 14.50 J/TH for $5,699, in a 2U closed-loop hydro chassis running at roughly 35 dB — among the quietest units sold.
- ✓ At the OneMiners Nigeria rate of $0.048/kWh the estimated margin is $12.87 a day, about $14,100 over three years against a $5,699 hardware cost.
- ✓ Break-even electricity price is around $0.110/kWh, so it loses money at typical residential tariffs. A genuine third manufacturer, designed in the United States.
For most of Bitcoin mining's history, buyers have had two real choices of supplier. That concentration has costs: pricing power sits with the manufacturers, lead times move at their convenience, and a single trade dispute can disrupt an entire industry's hardware pipeline.
Auradine is a Santa Clara company building an answer to that. The Teraflux AH3880 produces 600 TH/s at about 8,700 W — 14.50 joules per terahash — in a 2U hydro chassis rated at roughly 35 decibels. It is not the most efficient miner on the market. It is, however, the most credible third option, and at $5,699 it is priced to be considered.
What Auradine is, and why a third supplier matters
Auradine designs its hardware in the United States and has positioned itself around domestic Bitcoin mining infrastructure. For buyers, the practical consequences are supply-chain diversification, a different tariff and import exposure, and a support relationship that does not run through the same channels as the incumbents.
None of that shows up on a spec sheet, and none of it earns you a single satoshi. But if you have ever waited three months for a replacement hash board, or watched a tariff announcement reprice your next order, you already understand why a third serious manufacturer is worth something.
The AH3880 itself is a closed-loop hydro design that needs remarkably little coolant — around one litre — with a flexible flow requirement of 5 to 20 litres per minute. It cannot run without liquid cooling, and it requires a complete external loop including a cooling distribution unit, pumps, piping and a heat exchanger.
What 14.50 J/TH means in practice
J/TH is the electricity a miner spends to make one trillion attempts at the Bitcoin puzzle. Lower is better. At 14.50 J/TH the AH3880 sits behind current flagship hardware, which reaches about 9.45, and ahead of genuinely old equipment near 20.
The consequence is its break-even electricity price — the rate at which it earns exactly what it costs to run: roughly $0.110 per kWh. That is a tight number, and it is the most important thing to know before buying. Below about eight cents this unit works well. Above eleven cents it does not work at all.
This is the trade Auradine is asking you to make: a lower purchase price and a diversified supply chain, in exchange for a narrower band of electricity prices where the hardware makes sense. Whether that trade is good depends on your site, not on the manufacturer.
Estimated earnings and the arithmetic behind them
Mining revenue is your share of the network's computing power multiplied by what the network pays out, expressed as hashprice: the estimated dollars one petahash per second earns per day.
On 8 September 2026, with Bitcoin near $78,450, network hashrate around 925 EH/s and difficulty at 127.45T, hashprice worked out at about $38.16 per PH/s per day. At 0.600 PH/s the AH3880 grosses an estimated $22.90 a day.
It consumes about 209 kWh a day. At the OneMiners Georgia hosting rate of $0.060 per kWh electricity costs $12.53, leaving an estimated $10.37 a day. At the network's cheapest standard rate of $0.048 per kWh the margin rises to about $12.87. At a typical home rate of $0.12 per kWh it becomes a loss of roughly $2.16 a day. All figures are estimates.
How it compares with three other OneMiners Bitcoin miners
The WhatsMiner M6DS++ is the closest competitor: 604 TH/s at 15.50 J/TH for $4,291. It costs about $1,400 less and earns marginally less per day. Purely on the numbers the MicroBT unit returns capital faster; the Auradine is slightly more efficient and quieter.
The WhatsMiner M73S at 560 TH/s and 13.50 J/TH is the more efficient of the three, with a break-even price near $0.118 per kWh. If your electricity is at the higher end of viable, that extra headroom is worth paying for.
What it takes to run one
A 2U chassis and 35 decibels do not make this a domestic device.
- Power. About 8.7 kW continuous on commercial supply with appropriate protection.
- External cooling loop required. You need a cooling distribution unit, pumps, piping and a heat exchanger. The miner will not operate without them.
- Low coolant volume. Around one litre internally, with flow of 5 to 20 litres per minute — a flexible requirement that makes it easier to integrate into an existing loop.
- Noise. Roughly 35 dB at the chassis, among the quietest figures in Bitcoin mining, though the CDU and outdoor plant add site-level noise.
- Rack format. 2U, so it packs more densely than a 3U unit for the same floor space.
Why the electricity price decides this one
Electricity is typically 75 to 85 per cent of the ongoing cost of running a Bitcoin miner. With a break-even rate near $0.110 per kWh, the AH3880 has less tolerance than most, so the rate you pay is not a detail — it is the whole investment case.
At the cheapest hosting rates this unit covers its purchase price in around fifteen months, helped by the low $5,699 entry cost. From $0.12 per kWh upwards there is no payback, because there is no margin to pay anything back with.
The low price is what makes the AH3880 interesting, and cheap power is what makes the low price count. Without the second, the first is irrelevant.
Who should buy the Teraflux AH3880
- Operators deliberately diversifying suppliers. If manufacturer concentration is a risk you actively manage, this is the most credible alternative available.
- US-based buyers. Domestic design and support may simplify tariffs, lead times and service compared with imported hardware.
- Noise-sensitive sites. At around 35 dB the chassis is exceptionally quiet for 600 TH/s.
- Not for anyone above about $0.09 per kWh. The break-even rate near $0.110 leaves too little room.
Strengths and weaknesses
Strengths
- Low entry price at $5,699 for 600 TH/s.
- Around 35 dB at the chassis, among the quietest units in the market.
- 2U format for dense racking, with a flexible 5 to 20 litre-per-minute coolant flow.
- A genuine third manufacturer, designed in the United States.
Weaknesses
- 14.50 J/TH gives a tight break-even price of about $0.110 per kWh.
- Loses money at typical residential electricity prices.
- Requires a full external cooling loop including a CDU — it cannot run without one.
- A smaller service and spares network than the two established manufacturers.
Hosting or self-hosting
Self-hosting an AH3880 means building a commercial supply plus a complete cooling distribution unit, pumps, piping and heat exchanger — and then paying electricity that in most of Europe and North America starts at or above this miner's break-even price. The hardware is affordable; the infrastructure and the power rarely are.
OneMiners runs 20 sites with roughly 2,163 MW of contracted capacity at an average of about $0.0480 per kWh and 98 per cent or better average uptime. The Georgia, USA facility runs at $0.060 per kWh on premium hosting with import taxes optimised to 1 per cent, a seven-year hardware warranty and 95 per cent-plus guaranteed uptime; a seven-year prepaid contract there reaches $0.045 per kWh, the lowest rate on the network. For a US-designed miner, a US site is a tidy fit.
What that looks like over the long term
At $0.048 per kWh the estimated margin of $12.87 a day is about $4,700 a year, or roughly $14,100 over three years — around two and a half times the $5,699 hardware cost. At $0.060 per kWh in Georgia it is closer to $11,400 over three years. At $0.12 per kWh the three-year figure is negative.
Treat any three-year total as an upper bound rather than a forecast. Difficulty has risen across almost every multi-year window in Bitcoin's history, and rising difficulty shrinks each miner's share of the reward. A unit with a break-even rate near eleven cents has limited room to absorb that, which is why the cheapest power available matters more here than the purchase price does.
Frequently asked questions
Who makes the Auradine Teraflux AH3880?
Auradine, a company based in Santa Clara, California, which designs Bitcoin mining hardware in the United States. It is the most established alternative to the two incumbent manufacturers, and its presence gives buyers a genuine third source for supply-chain and support diversification.
How much does the AH3880 earn per day?
An estimated $22.90 in gross revenue at a hashprice of $38.16 per PH/s per day. After electricity the estimated margin is about $12.87 a day at $0.048 per kWh, or a loss of roughly $2.16 at $0.12 per kWh. These are estimates, not guaranteed earnings.
Is 35 dB really that quiet?
For a miner producing 600 TH/s, yes — it is around the level of a quiet library. It is achievable because hydro cooling removes the high-speed fans that make air-cooled miners so loud. Bear in mind that the cooling distribution unit and outdoor heat exchanger add noise at site level.
What cooling equipment do I need?
A complete external loop: a cooling distribution unit, pumps, piping and a heat exchanger. The miner holds only about one litre of coolant internally and accepts a flow of 5 to 20 litres per minute. It cannot operate without liquid cooling.
How does it compare with the WhatsMiner M6DS++?
The M6DS++ produces 604 TH/s at 15.50 J/TH for $4,291, against the Auradine's 600 TH/s at 14.50 J/TH for $5,699. The MicroBT unit is cheaper and returns capital faster; the Auradine is slightly more efficient, quieter, and comes from a different supply chain. On pure numbers the M6DS++ leads narrowly.
What is the break-even electricity price?
Roughly $0.110 per kWh at current conditions. Below that rate it earns a margin; above it, electricity costs more than the miner earns. It is a tighter figure than flagship hardware offers, so a cheap and stable rate matters a great deal here.
Is a third manufacturer actually worth paying for?
It depends on how you value risk. Diversification does not increase your daily revenue, but it can reduce exposure to lead times, tariffs and single-supplier disruption. For large operators that is a real consideration; for a single-unit buyer, the daily numbers should probably decide.
Weigh the diversification against the efficiency
The honest summary is that the AH3880 is competitive rather than dominant. Multiply your electricity rate by 209 to get the daily power cost, set it against an estimated $22.90 of revenue, and check the result against a break-even rate near $0.110 per kWh before you commit.
Current pricing, specification and availability are on the Auradine Teraflux AH3880 product page, and you can compare it against every alternative in the most profitable Bitcoin miners collection.
For a miner with this break-even rate, hosting is not optional in most places — it is what makes the purchase viable. OneMiners provides the commercial supply, the cooling loop, the monitoring and the repairs, and you keep ownership of the hardware and everything it mines.
Risk and profitability disclaimer
Every earnings figure in this article is an estimate, not a promise. Estimates were calculated on 2026-09-08 using a Bitcoin price of $78,450, a network hashrate of 925 EH/s, a difficulty of 127.45T and a resulting hashprice of about $38.16 per PH/s per day. All four of those inputs change constantly.
Mining revenue rises and falls with Bitcoin’s price, network difficulty, transaction fees, pool fees, your uptime, ambient temperature and the quality of your cooling. Costs rise and fall with electricity prices, hosting service fees, shipping, import duties and repairs. Nothing here is guaranteed, risk-free or always profitable, and none of it is investment advice.
Prices, specifications, batch dates and stock levels were taken from the OneMiners store on the date shown and can change without notice. Confirm the current figure on the product page before you buy. Manufacturer specifications carry their own tolerance, usually around plus or minus five per cent on both hashrate and power draw. Mine only with money you can afford to put at risk.
