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.

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.

How this unit was tested

A used-hardware seller who will not tell you how they test is asking you to take the grade on trust, so the procedure is public: the six-step bench procedure a machine goes through before it gets a grade and a listing, 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 arrives, run the 48-hour acceptance test before the freight claim window closes.

Condition, warranty and returns

Condition: Repair part or bench tool — this shelf holds both new spares and as-is units, so read the condition stated in the description.

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.
