I'm considering buying a used graphics card, but I want to avoid getting scammed or ending up with one that fails shortly after purchase. What should I check before paying, and what types of sellers or buying arrangements are safest?

If possible, test the card in your own PC or ask the seller to demonstrate it running. Check that the model matches the listing, inspect the PCB, fans, ports, and connectors, and run a demanding game or benchmark while monitoring temperatures, clocks, and visual artifacts. Also confirm that the card performs roughly as expected for its model. Don’t pay unless you can verify it works or have a clear return period or buyer protection.
For a local purchase, bring a system that can run the GPU, or only meet at a place where the seller can test it properly. Look for flickering, colored blocks, crashes, excessive fan noise, overheating, or suspicious repairs. Avoid sellers who refuse testing, rush you, offer a price far below normal, or provide no proof that the card is theirs. Keep the conversation and payment records in case there is a dispute.
A reputable marketplace with buyer protection is safer than an anonymous cash sale, but availability depends on your country. If local options are limited, ask for the card’s serial number, original purchase information, recent test results, and a short return guarantee. Be especially careful with cards that were heavily mined on; they may still work, but worn fans and aging memory can make them less reliable.

Even a card that passes a test can fail later, so testing isn’t a guarantee. A return window or some kind of warranty is just as important.
