MSI RTX 4090 SUPRIM LIQUID X 24G graphics card

Liquid-cooled flagship GPU

The MSI RTX 4090 SUPRIM LIQUID X 24G is a refurbished graphics card built around the NVIDIA GeForce RTX 4090 chipset. It delivers 16384 CUDA cores and 24GB of GDDR6X memory across a 384-bit interface. A closed-loop liquid cooler manages the 450W thermal design power. The card connects via PCI Express 4.0 and requires a 1000W power supply with a single 16-pin connector.

Upgrade from air-cooled 4090

This model replaces a standard air-cooled RTX 4090 when lower GPU temperatures and quieter operation are priorities. The liquid cooler moves heat directly to a case-mounted radiator instead of recirculating it inside the chassis. The jump is worth it for sustained heavy workloads such as 4K rendering or extended AI inference where thermal throttling would otherwise limit boost clocks.

Suited for 4K creators and AI developers

The 24GB frame buffer and 16384 CUDA cores suit professionals working with high-resolution video timelines, large 3D scenes or local large-language-model inference. Four display outputs (one HDMI 2.1 and three DisplayPort 1.4a) drive multi-monitor setups at up to 7680 x 4320. Buyers needing a smaller 280 mm card for compact cases or a lower TDP for modest power supplies should consider other models.
