German scammer dupes two different buyers into spending thousands on hollow RTX 5090 GPUs — stripped-out cards netted fraudster $5,000 despite being worthless

Nvidia’s GeForce RTX 50-series (codenamed Blackwell) graphics cards continue to rank among the best graphics cards available today. As a result, these highly sought-after Blackwell graphics cards have become prime targets for criminals seeking to scam unsuspecting buyers. Although scams involving hollow graphics cards are not new, their growing frequency and spread are cause for concern. The latest reports from Germany have revealed at least two buyers who fell prey to the same scam, reportedly from the same seller.

Hollow or phantom graphics cards may not be colloquial terms you hear every day. They basically refer to graphics cards that lack the silicon and memory chips. Criminals remove these components and sell non-functional graphics cards to their prey. Logically, you have no way of knowing these components are not present until you disassemble the graphics card, something that the average consumer does not do. Swindlers have run similar scams with fake memory modules without integrated circuits, or SSDs with microSD cards inside.

The first report, as recounted by respected hardware enthusiast Roman “der8auer” Hartung, uncovers a poor victim who bought a second-hand Palit GeForce RTX 5090 GameRock OC for around $2,090 (1,800 euros). The seller’s asking price was suspicious since a brand-new one starts at around $5,805 (4,999 euros) in Germany. Even for a used one, the dramatic price difference indicates a potential scam.

Many of these scams happen through online transactions. So the buyer went so far as to meet the seller in person, hoping a face-to-face interaction would ensure the graphics card was legit. It did not make a difference, though, because the buyer did not have a system to test the graphics card on the spot. In the end, it was a matter of taking the seller’s word for it, and that turned out horribly.

A second report has emerged from a member of the Hardwareluxx forums, who reportedly fell victim to the same deceptive seller. Tragically, this individual ended up paying close to $2,613 (2,250 euros) for the phantom graphics card.

In both cases, the scammer put on a friendly facade and provided what seemed like legitimate paperwork to bolster the buyers’ trust. For the first victim, the seller shared an invoice showing the purchase of two graphics cards, claiming to sell one because they no longer needed it. Similarly, in the second case, the scammer furnished an invoice to convince the buyer of the transaction’s legitimacy.

The use of realistic invoices is a growing trend among fraudsters. The first buyer uncovered that the serial number printed on the graphics card itself did not match the serial number listed on the packaging. The second buyer discovered that the serial numbers on the invoice and the packaging matched, but the seller deliberately scratched off the serial number on the graphics card.

The AI gold rush will not be over anytime soon, so we do not expect graphics card pricing to improve. This gives scammers more motivation to prey on buyers’ desire for a graphics card and lure them in with prices that seem too good to be true. The two incidents serve as a cautionary tale for anyone trying to procure a graphics card, especially from second-hand sources.
