Bitmain Antminer S19 PRO 110Th/s Hash Board Bitcoin Miner Hashboards
A set of Antminer S19 Pro hashboards — boards only, not a complete miner. A hashboard has no control board, PSU, fans or chassis and does nothing on its own. For reference a whole S19 Pro is 110 TH/s at 3,250 W (29.5 J/TH) and uses three hashboards. Condition and tested hashrate are not stated on this listing — ask us and we will tell you exactly what we have.

Description
These are hashboards, not a miner. A hashboard is one of the three boards inside an Antminer S19 Pro that actually do the hashing — it has no control board, no power supply, no fans and no chassis, and on its own it does nothing at all. We are saying this first because the previous version of this page carried a complete S19 Pro spec sheet, which at this price would be a remarkable bargain and is not what is being sold.
What an S19 Pro hashboard is, and what a complete machine looks like
For reference, a whole Antminer S19 Pro is 110 TH/s at 3,250 W, which is 29.5 J/TH. Those are the manufacturer’s figures. It reaches them with three hashboards working together under one control board, so a single board is very roughly a third of the machine’s output — and only once it is installed in a working machine with a control board that accepts it.
Two corrections to what this page used to say, recorded here because getting a spec wrong on a listing is how buyers end up filing chargebacks:
- It published 3,100 W and 36 J/TH. Both are wrong for an S19 Pro 110T, and they also contradict each other — 3,100 W divided by 110 TH/s is 28.2 J/TH, not 36. The real figures are 3,250 W and 29.5 J/TH.
- It listed “Type: Bitcoin Miner” and an input voltage range. A bare hashboard has neither; it takes DC from the machine’s PSU through the backplane, not mains.
Before you buy a hashboard
Hashboards are bought for one of two reasons and they are very different purchases. If you are repairing a machine, you need the board to match the generation and the control board you already have, and you should expect to test it before you trust it. If you are buying stock to repair and resell, you are buying a project, and the deciding question is whether the fault is in a chip or in the power domain feeding it.
Either way, work out how you will test it before it arrives. A board-level fixture such as the K3L multi-function tester or the universal hashboard tester is what turns “it does not work” into a chip number. There is also a BM1366 chip tester for the later S19 XP and S19k Pro generation, though note it does not cover this board’s chip family.
Condition and warranty
This listing does not state a condition grade, a hashrate measured on these specific boards, or a warranty term — so we are not going to imply one, and we are certainly not going to reprint a machine’s factory spec as though it described these boards. Ask us before you buy and we will tell you what we actually have: how many boards, whether they have been powered up, and what they did if so. Ask us about these boards.
If you would rather buy a board with a known state, we usually have a tested-working S19 Pro 95TH hashboard and an S19 XP Pro board sold openly as-is. Control boards, fan assemblies and the rest of the repair stock are in repair parts and tools — including tested Antminer control boards, which is the other half of a working machine.
What’s in the box
- 1 × Bitmain Antminer S19 PRO 110Th/s Hash Board Bitcoin
- No power supply. This listing states the PSU is not included — budget for one separately
- 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
Questions buyers ask about this part
Is this a complete, working machine?
No. This listing is on the parts and repair shelf, which holds both brand-new spares and bench tools and as-is units sold for repair. Which of those this one is, is stated in the description above — read it before you order, and ask us on +1 (781) 577-0377 or ns@ingmining.com if anything about compatibility with your fleet is unclear. We would rather answer the question than take a return.
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.

Where this listing sits
This one is on the parts and repair shelf. That shelf holds two different things: brand-new spares and bench tools, and as-is units sold for repair. Which of the two this listing is, is stated in its own description — read it before you order.
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.
