Used Antminer S19 95TH/s - VNiSH Low-Power Tune, 2800W

Description

A Bitmain Antminer S19 running VNish firmware on a low-power tune. The S19 is the workhorse of the SHA-256 fleet market: 95 TH/s and 3,250 W from the factory, three BM1398 hashboards, integrated APW12 PSU, and a repair-parts supply chain that is still wide open years after launch. That last point is why we keep buying them — when a board fails you can actually get a replacement.

What the “2,800 W tune” actually means

Straight answer, because this matters: a tune is a trade, not free money. VNish lets you drop chip voltage and frequency to pull wall draw down from the factory 3,250 W to around 2,800 W, and efficiency in J/TH improves when you do it — but hashrate comes down too. 95 TH/s at 2,800 W would be 29.5 J/TH, and BM1398 silicon does not reach that number. Expect the tuned hashrate to land below the 95 TH/s factory figure.

We are not going to guess at the exact pair for you. Ask us and we will read the actual tuned hashrate and the measured wall draw off the specific unit before you pay. Every chip bin is different and ambient temperature moves the number.

Here is the number that tells you whether the answer is a good one. The factory pair is 34.2 J/TH. At 2,800 W, a tuned machine matches that only if it still hashes 81.8 TH/s or better — 2,800 ÷ 34.2. Above 81.8 TH/s the tune has genuinely bought you efficiency; below it, you have simply given up hashrate and moved nothing. Ask for the as-tested figure and do that one division before you pay.

Condition

This unit ships with VNish already flashed, which means it is a production machine and not factory-sealed stock. Ask us to confirm the grade (tested-working vs. refurbished), what has been replaced, and what warranty we are putting on it before you order — we will put it in writing. We do not blur used into new.

Power and siting — read this before you buy

An S19 is a 200–277 V AC machine. It will not run on a standard North American 120 V outlet, and at roughly 3.25 kW it needs a dedicated 240 V circuit with real headroom — a 20 A 240 V breaker per machine is the practical floor. It is also a genuinely loud industrial appliance at about 75 dB. This is a shed, garage, warehouse or hosted-facility miner, not a living-room miner. If you want something you can put in a house, look at the Avalon Q instead.

Buying more than one? See the refurbished S19 lots — 20, 40, 50 and 300-unit pallets price very differently to singles.

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.

Not sure a 3.25 kW machine is the right first purchase? NerdQAxe++ vs Antminer S19 compares this machine against a desk-sized solo miner, with the break-even electricity rate for each derived from network difficulty — the S19 needs power under about 3.9 ¢/kWh to earn anything at all.

Questions buyers ask about this machine

Will this run on a normal household outlet?

No. This machine needs a dedicated 200–277 V circuit. A North American 120 V household outlet will not run it under any adapter or configuration. Have an electrician confirm the supply before the pallet arrives.

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.

What condition is it in, and what does that grade mean?

This is second-hand stock. We describe it the way we found it: tested working means it ran on our bench at the stated hashrate, refurbished means it was also cleaned, re-pasted or had parts replaced, and as-is means it is sold without a working claim. The grade for this unit is stated in the description above; where a listing states no grade, it says so rather than implying one. Cosmetic wear — dust, scratches, label marks — is normal on hardware that has been mining and is not a fault.

What should I check the day it arrives?

Photograph the pallet or box before you open it, keep the packaging, and run the 48-hour acceptance test straight away. Freight claim windows are short, and a fault found on day two is a conversation while a fault found on day thirty is an argument. Our own six-step bench procedure is published in full, so you can repeat exactly what we did.

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.

Is it worth repairing, and does used still win at this price?

At $159.99 this is the machine where the repair arithmetic stops working, and that is worth knowing before anything breaks. A tested-working S19 95 TH/s hashboard off our own parts shelf is $59.99 — 37% of what this miner costs. The rule we use, and the one the trade uses, is that a part costing more than about a third of the repaired machine’s value is not worth fitting. One board takes this unit past it. A S19 Pro 110 TH/s board set at $169.99 is more than the machine, and an APW12-class 5,600 W supply at $349.99 is more than twice it.

What still makes sense here is the cheap end: a S19/S20/S21 dual fan assembly at $24.99 and an APW9/APW12 power cable at $16.50. Those are the two failures worth preventing rather than repairing, because a fan that quietly stops is what cooks the board you then cannot afford to replace — why mining hardware fails has the order we actually see faults in. The honest spare for a $159.99 miner is a second $159.99 miner, not a shelf of boards, and if one does die past the point of repair, we buy used miners rather than leaving you with scrap.

Does used still win? On capital it is not close: $1.68 per terahash against the factory 95 TH/s rating, where a new S21 Pro 245T at $4,200 is $17.14 per terahash. You pay for that in efficiency — 34.2 J/TH against roughly 15 — so the decision is made by your electricity price and nothing else. On the low-power tune this unit hashes below 95 TH/s, so divide by the metered figure we send you, not the factory one. used vs new ASIC miners works out the exact rate where the two swap places.

Parts prices are our own shelf, read on 16 August 2026, and they are parts only — we do not publish a bench labour rate, so nothing here pretends to be a fitted price.

Where this listing sits

This one is on the used and refurbished shelf. It is second-hand hardware. The grade for this specific unit is stated in the description on this page — and where a listing states no grade, it says so rather than implying one.

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: Used — second-hand stock. The grade for this unit is on the listing above, and where a listing states no grade it says so.

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.
