Condition and warranty are not stated in this listing. We are not going to describe a used graphics card as new, or imply a warranty nobody has offered. Ask before you buy and we will tell you what the actual unit is and photograph it.

Do not buy this to mine with. We sell miners, and we are telling you not to.

The RTX 3090 was the card of the 2021 GPU mining boom. That ended on 15 September 2022, when Ethereum switched to proof of stake and deleted the only workload that made a rack of 3090s pay. What is left on GPUs is small, volatile altcoin mining that does not come close to justifying a card at this class of price, and a 24 GB Ampere card burns roughly the same wall power as a modern ASIC does per unit of useful work — except the ASIC is producing bitcoin. If your goal is hashrate per watt, buy an ASIC, not this.

What the 24 GB is genuinely worth paying for in 2026 is local AI work. Memory capacity is the binding constraint on running or fine-tuning models on one machine, and 24 GB on a 384-bit bus still puts this card in the same capacity class as hardware costing considerably more. That, plus 4K gaming and video work, is the honest case for it.

Check your case and your PSU rails

Three 8-pin connectors and a 2.9-slot cooler are the two things that catch people out. At 318.5 mm long and nearly three slots thick it will foul the drive cage in a lot of mid-towers, and ASUS asks for an 850 W supply with three genuine 8-pin PCIe leads — not one lead with two daisy-chained tails.

More networking and computer hardware in that hub, and the wider surplus and industrial equipment section.

Questions buyers ask about this card

What condition is this card in, and does it carry a warranty?

Neither is stated in this listing, so neither is claimed here. We are not going to describe a used graphics card as new or imply a warranty nobody has offered. Ask us before you buy and we will tell you what the actual unit is and photograph it.

Will it fit my case and my power supply?

Those are the two things that catch people out on this card. It is 318.5 mm long and 2.9 slots thick, so it will foul the drive cage in a lot of mid-towers, and ASUS asks for an 850 W supply with three genuine 8-pin PCIe leads — not one lead with two daisy-chained tails. Measure the clearance and count your leads first.

Should I buy this to mine with?

No, and we sell miners for a living. The workload that made a rack of 3090s pay disappeared on 15 September 2022 when Ethereum moved to proof of stake; what is left on GPUs is small, volatile altcoin mining that does not justify a card at this class of price. If you want hashrate per watt, buy an ASIC instead.

So what is the 24 GB actually worth paying for?

Local AI work. Memory capacity is the binding constraint on running or fine-tuning a model on one machine, and 24 GB on a 384-bit bus still puts this card in the same capacity class as hardware costing considerably more. That, plus 4K gaming and video work, is the honest case for it.

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 — on surplus stock we would much rather answer the question than take a return.

Where this listing sits

This is surplus, not mining hardware. We buy equipment lots and estate lots, and things arrive in them that have nothing to do with ASICs. Rather than force them into a miner category they do not belong in, they get listed for what they actually are, in surplus and industrial equipment. The condition of this item is whatever the description on this page says it is — and on several of these listings what it says is that the condition was never stated to us.

What our condition words mean

These are the only words we use, on surplus as much as on machines, 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	Second-hand, and it powered up and did what it is meant to do while we had it. What was actually checked is stated on the listing. Expect cosmetic wear.
As-is / for parts	Sold with no working claim at all, at a price that reflects it. Buy these to repair or to harvest.
Untested	We have it, we have not powered it, and we are not going to pretend we did.
Not stated	The most common answer on this shelf, and the honest one. Equipment lots arrive with no history, so where the listing does not name a condition we do not invent one — ask, and we will photograph the actual item and tell you what we can see.

What a condition here does not mean

Cosmetic wear is not a fault. Dust, scratches, scuffed labels and discoloured plastics are normal on equipment that has been in service. We photograph what we have; if the pictures matter to you, ask for more and we will take them.
A condition is not a warranty. Warranty terms are stated per listing, never per store — see the Shipping & buying tab. On surplus, assume there is none unless the listing names one.
A part number on the page is not a part number on the unit. Where a listing quotes a distributor catalogue or a manufacturer record rather than the label in front of us, it says so. Confirm against the actual label before you order anything that has to fit something else.
We will not invent a condition to fill a field. Several of these listings say outright that the import gave us no model number and no condition, and we would rather publish that than a guess that reads better.

How we describe surplus

There is no bench procedure behind these listings and we are not going to imply one. What is behind them is the unit, its labels, and the manufacturer’s own published record for the part number — and where those disagree, or where a distributor catalogue is the only source, the listing says which it is quoting. Before you buy anything on this shelf, ask us: we will photograph the labels on the actual item and put what we can see in writing. It costs us ten minutes and it is the only thing that reliably prevents a return.

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.

What to do the day it arrives

Photograph the pallet or the box before you open it, and keep the packaging until you are satisfied. Freight claim windows are short, and damage found on day two is a conversation while damage found on day thirty is an argument.

This is surplus stock rather than mining hardware, so there is no hashrate to verify on arrival. Check it against the part numbers, ratings and condition stated on this listing, and tell us straight away if what arrived is not what the page describes — that is the check that matters on equipment-lot stock, and it is the one we will stand behind.

Condition, warranty and returns

Condition: Condition not stated on this listing, so none is claimed — ask and we will confirm in writing.

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. On surplus stock in particular, assume none unless this listing names one.

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.
