A customer sent four broken graphics cards to a Chinese repair shop after spending thousands of dollars. The technician discovered three fake RTX 4090 cards that sellers had made from older RTX 3090 and RTX 3080 models. Scammers often modify old computer parts and sell them as expensive new equipment. The fake cards cost around $1,400 each from overseas sellers. Regular buyers cannot easily spot these modified graphics cards without technical knowledge.
Expert technicians can identify fake cards through small details on the circuit boards. One fake card showed a capacitor sticking out from the top right corner. Another sample had a QR code placed higher than normal on the bottom section. The third fake card used completely wrong circuit board materials that looked obviously different. Even though scammers engraved fake model numbers on the chips, laser machines make this process simple.
The fourth card turned out to be genuine but had broken memory parts and capacitors. The repair technician fixed the real card and made it work properly again. The customer decided to send the three fake cards back to the original seller. Computer scams like this happen frequently when people buy expensive graphics cards from unknown sources. Buyers should purchase from trusted retailers to avoid these expensive mistakes.
