Description
A power kit for running a 240 V Antminer from 110 V household supply. This is the most-asked question we get from first-time buyers, so here is the straight electrical answer before you spend anything.
The problem this solves
Most modern ASICs are 200–277 V AC machines. An Antminer S19 at 3,250 W will not run on a standard North American 120 V outlet at all — and even if the voltage were acceptable, 3,250 W at 120 V is about 27 A, while a normal 15 A branch circuit is rated for 12 A continuous. You are roughly a factor of two short on the circuit before you even get to the voltage problem.
So there are only three honest options: run a proper 240 V circuit, use a step-up arrangement fed from two adequately sized 120 V circuits, or run a miner that was designed for 110 V in the first place — the Canaan Avalon Q is the sensible example of the third. A kit like this addresses the second.
What you must check before you order
- Your miner’s actual wall draw. A 3.25 kW S19 and a 1.6 kW home miner are completely different asks.
- How many separate 120 V circuits you genuinely have. Two outlets on the same breaker is one circuit, and it will not help you.
- The breaker rating and the wire gauge feeding those outlets. Continuous loads are limited to 80% of breaker rating for a reason.
- Exactly what is in this kit. Contents and rated capacity are not itemised in the listing, so we are not going to list them from guesswork. Message us with your miner model and your electrical situation and we will tell you precisely what this kit includes and whether it is right for your machine.
What we would actually do
If you are running one machine and you own the building, pay an electrician for a dedicated 240 V circuit. It is a few hundred dollars, it is safer, it is more efficient (less current means less loss in the wire), and it is the last time you have to think about it. Adapter kits are the right answer when you are renting, when you are testing a unit temporarily, or when a 240 V run genuinely is not possible. They are not the right answer for a permanent multi-machine install.
Whatever you do, do not improvise this. 3 kW of continuous load on undersized wiring is a fire, not an inconvenience.
Before you order
We repair this hardware in-house, so if you are not sure the part fits, send us the model and the silkscreen part number off your board and we will check it against stock. More spares and test gear in repair parts & tools, or browse all miners.
The full electrical picture — continuous-load limits on 120 V and 240 V circuits, and what a derated miner actually produces — is set out in our ASIC miner buying guide.
What’s in the box
- 1 × Antminer power kit, 110 V to 240 V
- 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
Condition and warranty
This listing does not state a condition grade or a warranty term, so we are not going to imply one. The parts and repair shelf carries both new spares and as-is units, so the category is not the answer either. Before you buy, ask us and we will tell you what we actually have — new sealed, opened, bench-tested, or untested — and put any coverage in writing. Ask us about this unit.
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.
A site cost, not a machine cost — which is the whole difference
At $599.99 this kit costs more than three of our cheapest used S19s, and that comparison is the wrong one. A hashboard is spent per machine; a supply arrangement is spent once and then divided by everything plugged into it. Over one miner this is $599.99 of overhead on a $159.99 purchase and the arithmetic is grim. Over five it is $120 a machine. Over ten it is $60, which is roughly the price of a spare hashboard and nobody argues about that.
So the question is not whether the kit is expensive, it is how many machines will ever sit behind it. If the answer is one, an electrician quoting a 240 V circuit is usually the cheaper end of the same conversation, and a miner designed for 110 V — the Avalon Q — is cheaper still. If the answer is five or more, this is ordinary site infrastructure and it should be costed like the freight and the racking rather than blamed on the miner. how to buy a used ASIC miner puts site cost inside landed cost per terahash; fleet economics does the same arithmetic per megawatt for anyone sizing a room rather than a bench.

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.
