A buyer who thought they had purchased an ASUS ROG GeForce RTX 4090 sent the dead card to North West Repair. The shop found a cracked circuit board, a melted power connector, poorly placed thermal pads and a GPU marked AD103-300-A1—a chip associated with RTX 4080 silicon, not the RTX 4090. HotHardware and Tom’s Hardware reported the incident on January 22, 2024. It is a specific warning about verifying expensive computer hardware, not evidence of a measured rate of RTX 4090 counterfeits.
What the repair shop found inside the card
North West Repair’s inspection found extensive physical damage: the card had arrived with a large crack in its printed circuit board (PCB), and its power connector was melted. The shop also described the warranty sticker as fake and said the screws were unusually tight. After removing the shroud, the technician found thermal pads covering only about half of the memory chips.
The clearest sign of a parts mismatch was the GPU marking: AD103-300-A1. The reports identify AD103 silicon with the GeForce RTX 4080, while the RTX 4090 uses different Ada Lovelace silicon. The card therefore did not match what the buyer believed they had bought. Tom’s Hardware characterized it as a “no fix” card assembled from mismatched or damaged parts. Tom’s Hardware’s report and HotHardware’s account describe the inspection.
What is known about the Amazon purchase—and what is not
The buyer said the purchase came through an Amazon pallet deal. Coverage suggested a returned or tampered-with card may have entered a liquidation or returns channel, but that is an inference: the reports do not establish the card’s chain of custody or prove how it reached the buyer. The case does not establish that Amazon sold the card directly, nor does it quantify how often RTX 4090 scams occur.

North West Repair technician Tony warned that the incident was “100% real and it is now in the US marketplace.” That is a warning about this individual card and its circulation, not a published estimate of counterfeit sales or buyer losses.
Why a pallet or unusually cheap offer needs extra scrutiny
A clearance label or low price cannot authenticate a GPU. New, used, open-box and liquidation offers differ in provenance and buyer protection, so compare the source and the recourse you have if the card is wrong—not just the sticker price.

| Offer type | What to check |
|---|---|
| New | Whether the seller is authorized, whether the invoice identifies the product, and what return and warranty terms apply. |
| Used | Seller history, serial and packaging consistency, the reason for sale, and whether returns are permitted. |
| Open-box | Who inspected or resealed the item, what accessories or parts are included, and what protection covers a mismatch. |
| Liquidation or returns pallet | How much is known about each item’s history, whether individual-item returns are possible, and whether the seller can substantiate the product identity. |
For any category, compare the total price with normal market levels, check that the serial number and packaging are consistent, and keep a route to return or dispute the purchase. A card that looks right in a listing photo may still contain the wrong hardware.

- Choose a seller you can verify. Prefer an authorized retailer or other seller with a clear invoice, identifiable product and serial information, and explicit buyer-protection terms. Treat liquidation and returns pallets as a separate, higher-risk channel.
- Keep an unboxing record. Before installation, record the package, seals, labels and serial number, then capture the unboxing. Preserve the invoice and listing details so you can show what was advertised and what arrived.
- Keep payment and account activity on official channels. Review the order and seller through Amazon’s official website or app. Do not pay a seller by gift card: Amazon says legitimate transactions do not require gift cards. See Amazon’s guidance on gift-card scams.
- Check the installed hardware before your return window closes. Use trusted system tools to identify the GPU and its reported model and memory, then compare those details with the product specification. Run a sustained benchmark while you still have time to act on a mismatch or failure. Software identification and a benchmark can expose warning signs, but they do not replace seller provenance or a physical inspection.
- Stop if something is wrong. If the card is damaged, reports the wrong hardware or otherwise looks suspicious, stop using it. Keep the card and packaging as evidence, contact the seller and Amazon through official channels, and consider an inspection by a reputable repair shop.
What Amazon says about counterfeit enforcement
Amazon’s Counterfeit Crimes Unit says it works with “brands, law enforcement, and customers across the globe to stop bad actors.” The company’s current program page, accessed in 2026, says it has pursued more than 32,000 bad actors through litigation and criminal referrals since the unit launched in 2020. That enforcement figure describes Amazon’s program activity; it is not an RTX 4090 counterfeit rate or a measure of an individual buyer’s chance of encountering a fake. Amazon’s Counterfeit Crimes Unit page explains the program.
