APW12 10000W Immersion Cooling PSU Power Supply for ASIC Bitcoin Miner
A 10,000 W power supply in the APW12 form factor, built for submerged immersion rigs: 12–15 V DC output, conformal-coated PCB and two AC inlets.
- Fanless by design: cooled by the fluid it sits in. The same chassis is also sold air-cooled with three fans, and that is how people order the wrong one
- Why two inlets: 10 kW at 220 V is roughly 45 A — two separately protected circuits and cordage to match
- Listed against: Antminer T19, S19, S19 Pro, S19j and S19j Pro hardware
- Before you order: confirm with us which version you are getting
- Note: we list this supply twice. The fuller write-up is on the other APW12 10 kW immersion listing
- Condition: not stated in this listing — ask before you order and we will confirm it in writing
Price:
$849.99
- Condition graded per unit: new, tested working, refurbished or as-is
- Warranty and returns stated per unit, not per store
- Ships UPS Ground within 7 business days
Description
Read this before you order from this page. We list this power supply twice on this site, and the two listings are not priced the same. The other APW12 10,000 W immersion listing describes the same part — same 10,000 W rating, same 12–15 V DC output, same fanless conformal-coated construction, same two AC inlets, same vendor fitment list — at a different price. The two records were created from two separate source listings and we have not reconciled them, so before you order, ask us on +1 (781) 577-0377 or ns@ingmining.com which unit you would be sent and at which price. We will confirm it in writing.
A 10,000 W power supply in the APW12 form factor, built for submerged immersion rigs: 12–15 V DC output, conformal-coated PCB and two AC inlets. Vendors list it against Antminer T19, S19, S19 Pro, S19j and S19j Pro hardware.
APW12 10,000 W immersion PSU — ratings and fitment
| Form factor | APW12 |
|---|---|
| Rated output | 10,000 W |
| DC output | 12–15 V DC |
| Cooling | Fanless — for a submerged tank only. The fan apertures are empty because an immersion PSU is cooled by the fluid it sits in |
| Do not run it | In open air. The same chassis is also sold as an air-cooled unit with three fans fitted, and that is how people order the wrong one — run a fanless immersion supply dry and it will cook itself |
| AC inlets | Two. 10 kW at 220 V is roughly 45 A, which means two appropriately rated, separately protected circuits and cordage to match. Settle that with an electrician before the PSU arrives |
| PCB | Conformal-coated |
| Vendors list it against | Antminer T19, S19, S19 Pro, S19j and S19j Pro hardware. That is the vendors’ list, not a bench test of ours |
| Condition and warranty | Not stated in this listing, so nothing here claims either. Ask before you buy and we will tell you what we actually have — new sealed, opened, bench-tested or untested — and put any coverage in writing |
It is fanless, and that is not a fault — an immersion PSU is cooled by the fluid it sits in, so the fan apertures are empty. The same chassis is also sold as an air-cooled unit with three fans fitted, and that is how people order the wrong one. Run a fanless immersion supply in open air and it will cook itself. There are two AC inlets because 10 kW at 220 V is roughly 45 A, which is two separately protected circuits and cordage to match — settle the electrical side with an electrician before the PSU arrives, not after.
We list this supply in two places. The fuller write-up is on
the other APW12 10 kW immersion listing. Confirm with us which version you are getting before you order.
What’s in the box
- 1 × APW12 10000W Immersion Cooling PSU Power Supply
- 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.
What a 10 kW immersion supply is worth against the tank it sits in
The one-third rule does not apply cleanly to this part, and it is worth saying why. A hashboard is priced against one machine; a 10 kW supply in a submerged tank is feeding several, so measure it per kilowatt delivered rather than per miner — $849.99 across 10 kW is about $85 per kilowatt of supply, which sits in the same range as the $83 per kilowatt our 12 kW water-cooling radiator costs to reject. Those two numbers are the real capital cost of running immersion hardware, and neither of them appears on a miner’s spec sheet.
The failure case is what makes it expensive. This is a fanless unit. Run it in open air even briefly and it cooks itself, and a supply failure in a tank does not fail politely — it takes down everything it feeds at once. That is a different risk shape from an air-cooled fleet, where a dead $59.99 supply takes down exactly one machine. fleet economics covers the spares float an operator should carry against exactly this, and used vs new ASIC miners has the repair ladder for the air-cooled side of the same question.

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.
