The used GPU market has unwittingly become a playground for scams, and the latest drama involves none other than NVIDIA’s coveted RTX 4090. It seems that the hustle and bustle of the second-hand market on platforms like eBay and Craigslist has created fertile ground for fraudulent activities.
In a baffling incident shared by a Reddit user named piscian19, an RTX 4090 transaction went horribly wrong. This user sold the graphics card to an evidently established California-based business, boasting an impressive 30,000 feedback score. It seemed odd that such a buyer would offer retail price for a used unit, raising suspicion. Wisely, the seller documented the GPU with extensive photos and insured the shipment—a decision that turned out to be vital.
After the sale, the buyer promptly initiated a return, citing a “no video” issue, despite the card being in immaculate condition when dispatched. Upon receiving the returned GPU, the seller discovered it was laden with damage, including a bent mounting bracket, indicating it had been tampered with. Suspicion grew further when they opened the GPU to find the VRAM chips and GPU silicon had been removed.
Despite the buyer’s formidable feedback, this shady transaction unfolded, leading to suspicions of a hacked account. Meanwhile, speculation is rife that these components may find their way to China, destined for reassembly either into OEM models or high-VRAM variants for AI tasks.
This incident is a stark reminder of the current perils in the second-hand GPU market, underscoring the importance of vigilance and precautions, such as thorough documentation and purchase insurance, to fend off potential scams. As demand for high-end GPUs continues to soar, consumers are urged to exercise utmost care to avoid falling prey to such deceptive schemes.
