Antminer S19 XP 141TH/s Refurbished

Description

Bitmain Antminer S19 XP 141TH/s SHA‑256 Bitcoin ASIC Miner – BraiinsOS Compatible

The Bitmain Antminer S19 XP 141TH/s SHA‑256 Bitcoin ASIC Miner is a professional‑grade mining machine designed for high‑efficiency Bitcoin mining. Official Bitmain specifications confirm a maximum hashrate of approximately 141 TH/s with a power consumption around 3010 W, giving a published efficiency of about 21.5 J/TH (3,010 W ÷ 141 TH/s is 21.35 J/TH). This miner uses the SHA‑256 algorithm, suitable for mining Bitcoin (BTC) as well as other SHA‑256‑based cryptocurrencies. Built with robust hardware and reliable design, the S19 XP is one of Bitmain’s most advanced miners, optimized for both performance and longevity. This unit has been professionally refurbished and can run firmware such as BraiinsOS if you choose to enable advanced controls. BraiinsOS is widely used in the mining community to customize miner operation and optimize performance thresholds. While third‑party firmware may allow you to target higher throughput rates under certain conditions, the official verified S19 XP specification remains at 141 TH/s — and tuning above it costs efficiency rather than saving it, because power rises faster than hashrate on the voltage-frequency curve. A boosted machine is worse than 21.35 J/TH, not better. Every figure on this page is the factory rating, because that is the only pair of numbers with a manufacturer behind it. If you want the tuned figures for this specific unit, ask us and we will meter it. Each miner is tested to ensure stable operation and durability. With its energy‑efficient profile and solid construction, the S19 XP is suitable for medium to large mining operations. It takes 200–240 V AC and runs at roughly 75 dB, so it is a workshop, warehouse or hosted-facility machine. It will not run from a North American 120 V outlet, and it is not a machine to put anywhere people sleep or work. The miner connects via Ethernet and operates reliably within the recommended temperature and humidity ranges. Whether you are expanding an existing mining farm or establishing a new installation, the Antminer S19 XP provides a powerful baseline with professional capability.

What it costs to run

At the factory 3,010 W this machine draws about 72.24 kWh a day, or roughly 2,197 kWh a month at 730 running hours. That is about $154 a month at 7¢/kWh hosted power, and about $405 a month at the US average residential rate of 18.44¢/kWh (EIA, May 2026). At 16 August 2026 hashprice the S19 XP covers its own electricity only below roughly 6.1¢/kWh — above that it costs more to run than it mines. Difficulty, Bitcoin price and your power contract all move, so re-run the arithmetic on the day you buy using the formula in our ASIC miner buying guide.

At 21.5 J/TH the S19 XP sits between current-generation hardware and the older S19 class. The ASIC miner buying guide shows exactly which electricity prices that efficiency band still works at.

Weighing this against a new machine? A new S21 Pro is far more efficient but costs several times the capital, and which one returns your money faster depends entirely on your power rate — the used S19 XP wins below roughly 5.5¢/kWh and loses above it. We worked the whole comparison through in Antminer S19 XP vs S21 Pro.

The $379.99 S19k Pro on the same shelf — and when it is the better machine

We also stock a used Antminer S19k Pro at $379.99: 115 TH/s at 23 J/TH against this machine’s 141 TH/s at 21.35 J/TH. It is the honest alternative to this listing and for most buyers it is the one to take, so here is the comparison rather than a link to find it yourself.

Per dollar, the k Pro is far ahead. It costs $3.30 per TH/s against $4.96 here — about 50% more hashrate for the same money — and this machine’s efficiency advantage over it is only 7%. The arithmetic that settles it needs no Bitcoin price at all: buy the same total hashrate either way and both fleets earn identical revenue, so the whole decision is $1.66 more capital per TH/s here against 1.21 kWh per TH/s per month saved. At 3¢/kWh that premium takes about 46 months to come back; at 5¢/kWh, 28. Inside the band where either machine covers its own electricity at all, the efficiency premium on this machine does not repay quickly.

Two things do buy it back, and both are about your site rather than your spreadsheet. The first is machine positions: this miner and the k Pro each need their own 20 A, 240 V circuit, and this one puts 22.6% more hashrate on it (141 TH/s against 115). If your slot count is fixed — a container, a rented rack, hosting billed per box — that is a real gain, and the 26 TH/s of difference arrives at an effective 14.0 J/TH, which is current-generation efficiency. The second is the halving, roughly 608 days out at block 1,050,000: break-even rates halve with the subsidy, taking the k Pro to about 2.8¢/kWh and this machine to about 3.0¢. If your power sits between those, the halving ends a k Pro fleet and leaves this one earning.

Full arithmetic, payback tables and the crossover are in Antminer S19k Pro vs S19 XP. Figures on a 14 August 2026 snapshot at $31.05/PH/day, before any firmware dev fee and excluding the $49.99 per-machine US freight; the equal-hashrate figures above use no network inputs and do not move with the market.

Questions buyers ask about this machine

Will this run on a normal household outlet?

No. This machine needs a dedicated 200–240 V circuit. A North American 120 V household outlet will not run it under any adapter or configuration. At 3,010 W it draws about 12.5 A at 240 V, so the circuit wants a 20 A breaker — continuous loads are sized at 125% under the NEC, and a miner is the textbook continuous load. Size for your actual supply voltage, not ours: the same load on a 208 V feed draws more current, not less. Have an electrician confirm the supply before the pallet arrives.

What will it cost to run?

That depends on your electricity rate, so here is the part we can state exactly: at 3,010 W running 24/7, this machine burns about 2,167 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.

How loud is it?

~75 dB — about as loud as a household vacuum cleaner running continuously, and it does not stop. This is a garage, workshop, outbuilding or hosted-facility machine, not something to put in a room where people live or sleep.

What can I mine with it?

It mines Bitcoin (BTC) and other SHA-256 coins. The algorithm is SHA-256, 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.

If this has to run in a house, buy the Avalon Q instead

This machine takes 200–240 V only and runs at about 75 dB. There is no adapter that puts it on a North American 120 V outlet, and no power mode that makes it quiet. If your only option is a household circuit or a room near people, the Canaan Avalon Q at $1,999 is the machine that physically installs there — 110–240 V and 45–65 dB.

Everywhere else this one wins comfortably: $4.96 per TH/s against the Avalon Q’s $22.21, and payback three to four times faster at every rate where either pays back. We worked both machines through in Avalon Q vs Antminer S19 XP.

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

On this machine the question is not what a repair costs, it is whether the part exists at all — and that is the honest weakness of the S19 XP as a used buy. The XP is BM1366 silicon, and our parts shelf reflects what the aftermarket actually supplies: for the base S19 we stock a tested-working S19 95 TH/s hashboard at $59.99, tested. For the XP the only board we carry is a 141 TH/s XP-family board sold AS-IS for parts at $24.99, and a BM1366 chip tester at $599.99 for someone doing chip-level work. A donor board and a chip tester are not a repair path, they are a bench project. the parts compatibility guide explains why board revisions inside one family are not interchangeable; the short version is that BM1398, BM1362 and BM1366 machines are different platforms wearing similar lids.

What that means for the purchase. Buy this one tested and buy the condition, not the plan to fix it later — ask us for the metered hashrate, the wall draw and the board revisions in writing before you pay, and see what our grades mean for what our grades commit us to. Fans at $24.99 and an APW9/APW12 power cable at $16.50 still cover the two cheap failures.

Used versus new: $4.96 per terahash here against $17.14 for a new S21 Pro 245T at $4,200, and 21.35 J/TH against roughly 15 — the narrowest efficiency gap of any used machine on our floor, which is why the XP is the used unit that holds up best at mid-range power prices. used vs new ASIC miners works out where the crossover actually sits.

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.
