Chinese data centers are now selling off surplus RTX 4090 GPUs, modified and refurbished, after a drop in AI workload demand leaves racks sitting underused. Some upgraded models with 48GB of VRAM are being listed for as much as $5,500.
RTX 4090 sales surge as AI usage stalls in China

These GPUs were originally packed into server farms to power AI models, but many centers now report usage rates below 20%. At that level, the math stops working, operating costs eclipse returns, and idle RTX 4090 units become liabilities.
So the fix is simple: pull them, clean them, swap coolers, and sell. And that’s exactly what’s happening. The RTX 4090 is suddenly flooding resale markets, often reconfigured with blower-style fans to better suit tight consumer rigs.
Refurbished RTX 4090D units offer 48GB for a steep price
These aren’t off-the-shelf models. The RTX 4090Ds being resold were built for data center density, and they carry specs to match. With 48GB of VRAM—triple what the standard version offers—they’re commanding resale prices from $2,700 up to $5,500.
While the cooling mods aren’t ideal for solo use, they’re workable. And the value for GPU-heavy workflows like AI training or 3D rendering is drawing serious attention.
U.S. chip bans drive faster RTX 4090 sell-offs
There’s more urgency now thanks to export controls. After U.S. restrictions cut off Nvidia H20 and AMD MI308 chips, many data centers fear the RTX 5090D could be next. Selling RTX 4090 stock while they still can may be the safest bet.
With sales already moving fast, this isn’t just a supply story—it’s a warning shot. Geopolitics are reshaping the GPU pipeline, and data centers are trying to stay ahead of the squeeze.
RTX 4090 resale boom reveals cracks in AI demand
The RTX 4090 was once the poster child of AI acceleration in China. Now it’s hitting the resale market by the truckload. Not because it’s weak, but because the demand didn’t hold.
Some AI firms overbuilt, overhired, and overbought. Now they’re paying the price. As shiny as the AI gold rush looked last year, this wave of RTX 4090 refurbs shows the correction has already begun.
