Canaan Avalon Q 90T for Sale - 90 TH/s Home BTC Miner

Description

The Canaan Avalon Q is the one modern Bitcoin miner we will actually recommend for a house. 90 TH/s at 1,674 W and 18.6 J/TH, on a 110–240 V input so it runs off a normal North American outlet, at 45–65 dB depending on power mode, against the flat 75 dB an Antminer makes. That combination is rare and it is the entire reason this machine exists.

The 110 V caveat nobody mentions

Yes, it accepts 110 V. No, that does not make it weightless on a household circuit. 1,674 W on a 120 V line is roughly 14 A, and a standard 15 A branch circuit is only rated for 12 A continuous. In Super mode it needs a dedicated 20 A circuit with a NEMA 5-20R outlet. Run it at 240 V instead and it draws about 7 A, and the wiring stops being the limiting factor. Do not share the circuit with a space heater and then blame the miner.

This is where the three power modes earn their keep, because they are how the machine adapts to the circuit it is on:

Eco, ~800 W — about 6.7 A at 120 V. Comfortable almost anywhere.
Standard, ~1,300 W — about 10.8 A at 120 V, which fits inside a 15 A circuit’s 12 A continuous limit if nothing else is on it.
Super, 1,674 W — the full 90 TH/s, and the mode that needs the 20 A circuit.

One honest gap: Canaan publishes the wattage of each mode but not the hashrate, so treat 90 TH/s and 18.6 J/TH as the Super-mode figures. Derating normally improves J/TH and always reduces output, and we are not going to put a number on it that we have not measured ourselves. Ask us and we will measure it on a unit.

The 45 dB figure is what the machine does at its quietest, not what it does at 90 TH/s — published ratings run 45–65 dB across the modes, and 65 dB is audible through a wall. It is genuinely quiet for an ASIC — think a loud desktop PC, not a jet — but it is not silent and it puts 1.6 kW of heat into whatever space you leave it in. That heat is a feature in February and a problem in July.

What’s in the box

Listed as new, shipping from the USA, with an integrated power supply — there is no separate PSU to buy. Canaan publishes a 360-day warranty on the Avalon Q that runs from first device registration rather than from purchase, so register it promptly. Ask us to confirm in writing what coverage comes with this particular unit before you order. Confirm the power cord type for your region with us as well.

Buying from ING Mining

We buy, repair, host and resell this hardware ourselves, so ask us the awkward questions before you order — power draw at the wall, board revision, what the fans sound like in a garage. Browse the rest of the catalogue at all miners.

Weighing this against a cheap used industrial machine? Our head-to-head on the Avalon Q versus the Antminer S19k Pro works through the break-even rates, the 3.8-cent crossover where more terahash starts beating better efficiency, and the circuit each one actually needs.

Home mining has three constraints that catch buyers out: circuit amperage, heat and noise. All three are worked through with real numbers in our ASIC miner buying guide.

What this machine’s price premium actually buys

Straight about this, because the efficiency figure gets used to sell it and it should not be. At 18.6 J/TH the Avalon Q is about 13% more efficient than a refurbished Antminer S19 XP at $699.99. It is also $22.21 per TH/s against that machine’s $4.96.

Work the efficiency saving against the extra capital and it repays in 10 to 24 years at any electricity price where either machine is worth switching on — longer than an ASIC’s economic life. So do not buy this one for its J/TH. Buy it for the two things it genuinely gives you: it runs on a 110–240 V supply, so a North American household circuit works, and it runs at 45–65 dB instead of about 75. If the machine has to live where people live, it is the only one of the two you can install — and that is worth real money when it is true.

The full arithmetic, including the narrow 6.09–6.99¢/kWh band where this machine is the only one of the two still covering its power bill, is in Avalon Q vs Antminer S19 XP. Circuit and breaker sizing is on our power requirements page.

Questions buyers ask about this machine

What voltage does it need?

It accepts 110–240 V, so it will run on either a North American 120 V outlet or a 240 V circuit. Check the current draw against the breaker on whichever one you use.

What will it cost to run?

That depends on your electricity rate, so here is the part we can state exactly: at 1,674 W running 24/7, this machine burns about 1,205 kWh a month. Multiply that by your own all-in rate per kWh — including delivery charges, not just the supply rate — to get your monthly power bill. We do not publish profitability figures, because they change with difficulty and price every day.

What can I mine with it?

The algorithm is SHA-256 (Bitcoin), and ASIC silicon is single-purpose: it will mine coins on that algorithm and nothing else, whatever the price of anything else does.

Is this a new unit?

Yes — new stock, as described in this listing. Any manufacturer warranty term that applies is stated in the description above; where none is stated, none is claimed.

Shipping cost for this exact item, and how warranty and returns work here, are answered in the Shipping & buying tab on this page. Anything else, ask a person on +1 (781) 577-0377 or ns@ingmining.com — we would rather talk before you buy.

Where this listing sits

This one is on the new shelf. New stock, as described in the listing. Any manufacturer warranty term that applies is named in the description; where none is named, none is claimed.

What our grades mean

These are the only words we use, and each one means a specific thing. They are not interchangeable and we do not soften them to move stock.

New	Unused stock. Factory sealed unless the listing says otherwise — “new, open box” means exactly that, and the listing will say it.
Tested working	Second-hand, and it ran on our bench at the hashrate the listing states. We measured it; we are not repeating what the last owner told us. Expect cosmetic wear.
Refurbished	Tested working, plus work done: cleaned, thermal paste and fans dealt with, failed components replaced. The listing says what was actually done to that unit rather than using the word as decoration.
As-is / for parts	Sold with no working claim at all, at a price that reflects it. Buy these to repair or to harvest. If a listing says as-is, assume it does not hash until you have proved otherwise.
Untested	We have it, we have not powered it, and we are not going to pretend we did. Rarer than as-is and always stated explicitly.

What a grade here does not mean

Cosmetic wear is not a fault. Dust, scratches, scuffed labels and discoloured plastics are normal on hardware that has been earning. We photograph what we have; if the pictures matter to you, ask for more and we will take them.
A grade is not a warranty. Warranty terms are stated per listing, never per store — see the Shipping & buying tab. A tested-working grade describes what the machine did on our bench, not what we owe you in six months.
A boosted hashrate is not a spec. Where a unit ships on tuned firmware we say so and we give the factory figures too, because overclocking raises power faster than it raises hashrate — a tuned machine is less efficient per terahash than stock, not more.
We will not invent a grade to fill a field. If a unit came in without history and has not been through the bench, its listing says that.

How the grade gets decided

A used-hardware seller who will not tell you how they test is asking you to take the grade on trust. Ours is published: the six-step bench procedure every machine goes through, and the five measurements that get recorded — per-board hashrate, chip count, measured wall power rather than the nameplate figure, hardware error rate, and temperature under sustained load. When it reaches you, run the 48-hour acceptance test straight away, while the freight claim window is still open.

Buying second-hand for the first time? How to buy a used ASIC miner without getting burned is the long version, written from the repair bench rather than from a spec sheet.

Shipping

Shipping this item inside the United States costs $49.99 by UPS Ground — that is the rate the checkout will charge, read from the store’s own shipping settings, not an estimate. Orders ship within 7 business days.

Outside the United States the checkout quotes a flat international rate. On multi-unit or pallet orders, contact us before ordering so freight to your destination can be confirmed properly. What to check when the pallet arrives, and how a freight claim works, is covered in the mining hardware shipping guide.

What to do the day it arrives

Photograph the pallet or the box before you open it, and keep the packaging until you are satisfied. Freight claim windows are short, and damage found on day two is a conversation while damage found on day thirty is an argument.

Then run the 48-hour acceptance test straight away, while that window is still open. It is the same ground our own bench covers, so you can compare like for like: how the grade on this listing was arrived at, and the five measurements we record, are set out in the Condition & grading tab on this page.

Condition, warranty and returns

Condition: New — as described on this listing.

Warranty is stated per listing, not across the catalogue. Some units carry a manufacturer term and say so above, naming the term and the date it runs from. Many units, particularly used and AS-IS stock, carry none, and those listings do not claim one. There is no blanket warranty covering a catalogue that runs from sealed factory stock to a hashboard sold for parts. For what a mining warranty normally covers, see ASIC miner warranty explained.

Returns: ask for the terms on this unit before you pay. No single returns window is published for the whole store, because the sensible terms on a tested working machine and on a board sold AS-IS for parts are not the same terms. Email or call and ask what applies to this exact item — it is a two-minute conversation and a great deal cheaper than a dispute.

Where you are going to run it

Two questions decide whether a machine like this works where you live, and neither of them is about the miner: can the circuit carry it, and what does your electricity cost? Most full-size machines here want a dedicated 240 V circuit and run at 70–75 dB continuously. A few do not — the Avalon Q publishes 45–65 dB and runs on 110–240 V — so read the voltage and noise figures on this listing rather than assuming. ASIC miner power requirements covers breaker sizing and what the install actually involves; cooling covers where the heat and the noise end up.

If your power is not genuinely cheap, hosting is the question to be asking instead of which miner to buy. Break-even electricity rate is hashprice divided by (24 × J/TH), and hashrate cancels out of it entirely — which is why a cheap old machine on expensive power loses money faster than an expensive new one does. The buying guide has the arithmetic; work out your own number before you buy anything.

If hosting is the answer, get written answers on three things before you sign: who pays for repairs, what the uptime commitment actually pays out when it is missed, and how curtailment is handled. A flat per-machine monthly rate is where most of the unpleasant surprises live. Types of mining farm compares the models and hosting versus cloud mining covers why owning the hardware is the better end of that trade. Ask us before you commit — it is a five-minute call and a great deal cheaper than a contract you cannot get out of.

What we do once it is racked, wherever that is. Deployment, firmware and monitoring are a service we run rather than a line on a page: pool and network setup, Braiins OS or VNish tuning, offline alerts, and board-level fault-finding when a machine stops hashing — ASIC mining consulting sets out what that covers. The hosting agreement itself is between you and the facility. What we can give you is the number most hosting disputes turn on: what this machine measured at the wall on our bench, so a shortfall on site is a figure to compare against rather than an argument about what it should have been doing.
