Description
Forty Bitmain Antminer S19 units, 95 TH/s each. Roughly 3.8 PH/s of SHA-256 for about 130 kW of connected load. Forty machines is the size where a hobby stops being a hobby: it is a real electrical project, and it is also the size where per-unit pricing starts to make the S19 make sense again.

Condition
The listing does not state a grade for this lot, so we are not going to invent one. Message us and we will tell you exactly what these are — tested-working, refurbished, or as-is — along with the firmware on them and what happens if a unit arrives dead. That is a straight answer you should demand from any seller before wiring money for forty machines. If you specifically want refurbished units on VNish, see the refurbished S19 lots.
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.
Spares matter at this scale. Keep a couple of fan assemblies, PSUs and hashboards on the shelf — a machine sitting idle for a week waiting on a cheap fan costs far more than the fan.
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.
No grade is stated here, and that is the first thing to settle in writing
Forty machines is a genuine electrical project — about 3.8 PH/s for roughly 130 kW — and this listing does not state a condition grade. We would rather say so than invent one. Before anything else, get in writing which of three words applies: 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. You will not find A, B and C grades here, because no industry body defines them and a letter with no published method behind it commits a seller to nothing — what to ask for instead is in ASIC grading explained.
Then the part most buyers get wrong at this size: your bench is the bottleneck, not the pallet. Acceptance testing is rate-limited by the power you can energise at once, while the carrier’s window for concealed damage runs on a calendar regardless of how busy you are. Photograph every pallet before the wrap comes off, pull your first test units from different layers rather than off the top — machines that travelled at the bottom of a stack have had a different journey from the ones on top — and run a short does-it-hash pass across all forty before you burn in anything. The dead ones have to be found inside the claim window, not after it.
What a used batch commits us to, what happens when a unit arrives dead, and what a warranty does and does not cover across a lot are on bulk used ASIC miners. The delivery-day procedure itself — the freight receipt, the count, the serial reconciliation and the order the machines come up in — is at receiving a used miner lot.

The condition grade on this lot is not stated, and we would rather say so than imply one. The used-miner buying guide explains exactly what an unstated grade means, what to ask for, and how to price the risk of a forty-unit pallet.
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.
