Sell Used GPUs in Bulk
GTR Supply buys used and surplus graphics processing hardware in bulk, from workstation cards through to passively cooled data center accelerators. Quotes are issued against the exact part number, the memory size and the cooling type, because those three fields decide which buyers a card suits and cards that look alike from across a room are frequently not the same item. Values in this category move more than in anything else we buy. Supply arrives in bursts when compute fleets are refreshed, demand for the same parts is intense, and the two rarely line up. We do not put an expiry on a valuation. Come back to us whenever you are ready and we will reconfirm the number against the market on the day. Keep the brackets, blanking plates and power cables with the cards. They are part of the lot.
What we take
GPUs we buy.
- Passively cooled data center accelerators
- Workstation graphics cards in volume
- Desktop graphics cards by the lot
- Cards pulled from decommissioned compute nodes
- Cards still installed in the servers or workstations
- Brackets, blanking plates, riser cables and GPU power cables
- Mixed lots, listed by part number
Buying rather than clearing? See the GPUs we supply by the lot.
What your list needs
Write these down.
- The exact part number, from the sticker on the card or the end bracket
- Memory size per card, which two otherwise identical models can differ on
- Cooling type: passive with no fan, active blower, or axial fans
- Quantity against each part number
- Whether brackets, blanking plates and power cables are present
- Whether the cards are loose or still installed in nodes
- Physical condition of the PCIe edge connector and the bracket
Missing some of it?
Send it anyway and write unknown against the gaps. An honest gap is easy to price around. A wrong specification found at collection is what forces a valuation to be revised.
Not certain what is on the pallet? See the 10 families of GPUs that circulate on the secondary market and how to tell them apart, each with the part number prefix or the physical marker that identifies it. That page is identification help for writing this list rather than a stock list.
Identify what you have
Most of what a valuation needs is a model number read correctly. The catch with GPUs is that the number sits in a different place on every manufacturer's hardware, and reads differently once you have found it. These pages show where it physically is, how to read each field in it, and what the fields mean. They are identification help rather than stock lists. If typing the list is not realistic, a photograph of the right label is usually enough.
Every brand GTR Supply buys and sells, grouped by category, with the identification detail for each one.
What moves the number
Up, and down.
Condition is only part of it. Most of what decides a valuation is how the lot is put together and how accurately it is described, and both of those are still in your hands when you write the list.
Moves it up
- A batch of identical cards rather than a spread of single models
- Brackets, blanking plates and the correct power cables included
- Data center accelerators, which have a narrower supply than workstation cards
- Larger onboard memory, which decides what workloads a card can still run
- A prompt decision, because this category moves faster than any other we buy
Moves it down
- Bent brackets, damaged PCIe edge fingers or a cracked backplate
- Missing power cables and blanking plates, which have to be found before a card can be installed
- Older generations, which lose ground quickly as newer parts reach the used market
- Cards described by family name only, with no part number
- A valuation left to sit, since the figure was accurate on the day it was given

Common questions
Selling GPUs, answered.
How long does a GPU valuation stand?
GTR Supply does not put an expiry on a GPU valuation. There is no deadline to work to and no number of days after which a figure lapses. What is true is that values move more in this category than in anything else we buy.
There are two reasons it moves. Supply arrives in bursts, because accelerators come out of compute refreshes in large batches at unpredictable intervals rather than as a steady trickle. Demand for those same parts is intense and largely driven by AI buildouts, so a batch that lands does not sit around.
The practical consequence is that a figure reflects the market on the day it was given, and it can move in either direction from there.
So if you are working from a number we gave you a while ago, come back and ask us to reconfirm it. There is no penalty for taking your time and reconfirming costs nothing.
How do I identify which GPU I have?
Look for the part number rather than the family name. It is normally on a sticker on the side of the shroud, on the backplate, or on the end bracket where the display outputs would be on a workstation card.
The family name alone is not enough. Cards sold under the same name can carry different amounts of onboard memory, and memory size is one of the fields that decides what a card is still useful for, so a valuation built on the name only has to be revised once the cards arrive.
Data center accelerators often have no display outputs at all and no branding on the visible face, which makes the sticker the only route to a positive identification.
If the cards are still installed and the machines are reachable, the operating system or the management controller will report the model and the memory size for every card at once. Otherwise photograph the stickers.
Do I need to keep the brackets and power cables?
Yes, keep them with the cards. Brackets, blanking plates and GPU power cables all count as part of the lot, and a card missing its bracket has to have one found before it can be installed in anything.
The bracket is the piece most often lost. Cards get pulled, the bracket gets unscrewed to fit a different chassis, and the original ends up in a drawer. Low profile cards often shipped with two brackets, a full height and a low profile one, and having both is worth more than having either.
Power cables are the second most common gap. Data center and workstation cards frequently use a connector specific to the server they were installed in, and the cable is not something a buyer can readily substitute.
If items are missing, say so on the list rather than leaving it to be discovered. It is a much smaller issue when it is known in advance.
Is a passive data center card valued differently from a workstation card?
Yes, and the cooling type is one of the first fields GTR Supply looks at, because it decides who can actually use the card.
A passively cooled accelerator has no fan of its own. It is designed to sit in a server that pushes a specific volume of air across the heatsink, and it depends entirely on the host to do it. Put one in a workstation or a tower and it will overheat, throttle or shut down even though nothing about the card is faulty. That narrows the pool of buyers to people running the right chassis, and it is the reason we ask.
An actively cooled workstation card carries its own blower or axial fans and will run in a far wider range of machines.
So write the cooling type on your list next to the part number. Passive, blower or axial is enough, and it saves a round of questions.
Guides
Clearing GPUs is mostly a description exercise. These cover what a buyer is actually pricing and what the words on a quote mean before you agree to any of them.
Clearing more than one category?
Most decommissions are mixed. Send the whole list and we will value it as one lot rather than making you split it up first.
