A container-scale lot: 300 Bitmain Antminer S19 units at 95 TH/s each, sold tested and working. Roughly 28.5 PH/s of SHA-256 and about 975 kW of connected load.
- Per unit: 95 TH/s ±5% at 3,250 W ±5%, 34.2 J/TH, 3 × BM1398BB boards, integrated APW12, 200–277 V AC
- Fleet arithmetic: approx. 28.5 PH/s and 975 kW at the factory ratings — and effectively all of that 975 kW comes back out as heat to reject
- Freight: 14.2 kg net a unit on Bitmain’s own specification is roughly 4.26 tonnes bare, and about 4.8 tonnes gross once boxed at 16 kg a unit. Palletised freight, not parcel — talk to us before you order
- Condition: tested and working: the units hashed when tested. That is a working-order grade, not a refurbishment, and cosmetic condition varies across a lot this size
- Ask us before you commit: the test methodology, the pass criteria and the DOA policy on this lot

Description
A container-scale lot: 300 Bitmain Antminer S19 units at 95 TH/s each, sold tested and working. That is roughly 28.5 PH/s of SHA-256 and around 975 kW of connected load. Nobody buys 300 miners on impulse, so here are the numbers you actually need to plan a site.

| Algorithm | SHA-256 (Bitcoin) |
| ASIC chip | BM1398BB, 7 nm |
| Hashboards | 3 boards × 76 chips = 228 chips |
| Power supply | Integrated APW12 |
| Input voltage | 200–277 V AC |
| Cooling / noise | 4 fans, approx. 75 dB |

| Network | Ethernet (RJ45) |
What’s in the box
- 300 × Bitmain Antminer S19 95TH/s — this listing is the whole lot, not one machine from it
- Nothing that is not listed above. Cords, controllers, brackets and spares are only included when this listing names them — if you need to know before you pay, ask on +1 (781) 577-0377 or ns@ingmining.com and we will confirm in writing what is physically in the crate
What 300 units means at the site level
| Total hashrate | Approx. 28.5 PH/s (300 × 95 TH/s, factory rating) |
|---|---|
| Total connected load | Approx. 975 kW (300 × 3,250 W, factory rating) |
| Heat rejected | Effectively all of it — plan roughly 975 kW of ventilation or heat reuse |
| Fleet efficiency | 34.2 J/TH |
Those are arithmetic from the factory ratings, not a promise about these specific machines. Real fleets run a spread: some units come in under rating, a few will need a board. Budget for it.
Condition
Sold as tested and working. That is our working-order grade, not a refurbishment — it means the units hashed when tested, not that they were rebuilt. Cosmetic condition varies across a lot this size, and on any 300-unit purchase you should expect a small number of units to need attention on arrival. Ask us about the test methodology, the pass criteria and the DOA policy on this lot before you commit. Boards, fans, PSUs and control boards for anything that does fail are in repair parts & tools.
Logistics
At the Bitmain-published S19 specification net weight of 14.2 kg per unit this is roughly 4.26 tonnes of hardware bare, and about 4.8 tonnes gross once boxed at 16 kg a unit — palletised freight, not parcel, and the quote is priced on the gross weight. Talk to us about freight, palletisation, staging and delivery windows before you order; on a lot this size the freight and the receiving plan are a real part of the deal. Smaller lots of 20, 40 and 50 units are also available if you want to start smaller.
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 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.
Questions buyers ask about this lot
Will this run on a normal household outlet?
No. This lot 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.
Three hundred machines is a megawatt, and it is bought as one
About 975 kW of connected load is near enough a megawatt that the megawatt is the unit of purchase. On the hashprice derived at block 961,911 on 10 August 2026 on used ASIC miner fleet economics, a megawatt of stock 95 TH/s used S19s returns its purchase price in about 145 days at three cents a kilowatt-hour — and never at five or seven, because above their own 3.89-cent break-even the machines are under water. A megawatt of new SealMiner A2 Pro takes about 777 days at three cents but survives up to about 8.94 cents. That is the used-versus-new trade at this scale, and it is a choice between a fast return in a narrow power band and a slow return in a wide one, not a pitch.
The operational constraint at three hundred is that you cannot bench a pallet as fast as a pallet arrives. Acceptance testing is limited by the power you can energise at once — into a 200 kW service that is about sixty machines at a time, so a full pass is a queue several days long while the carrier’s concealed-damage window runs on a calendar. Plan the two against each other before the truck is booked, not after it is unloaded, and sample across the stack rather than off the top.
Tested and working means these hashed when they were tested. That is a working-order grade rather than a refurbishment, and cosmetic condition varies across a lot this size — ask us for the test methodology and the pass criteria, and settle the dead-on-arrival window and remedy in writing before the order goes in. What the word commits us to is defined on bulk used ASIC miners, and the freight, condition and repair-cost dataset behind a lot this size is published at used ASIC lot data.

Three hundred S19s is roughly 28.5 PH/s, about 975 kW of continuous load and over four tonnes of freight. Our used-miner buying guide works exactly this lot through as its fleet example, including testing methodology and DOA terms to agree in advance.
Delivery day on a lot this size is its own procedure — what to write on the freight receipt before you sign, reconciling the count and the serial numbers, why the machines come up in groups rather than together, and how to sort the ones that do not: receiving a used miner lot.
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.
