MSI RTX 4090 GAMING X SLIM 24G graphics card

Product identity

The MSI RTX 4090 GAMING X SLIM 24G is a refurbished graphics card built around the GeForce RTX 4090 GPU with 24GB of GDDR6X memory on a 384-bit bus. It targets creators and enthusiasts who need maximum frame-buffer capacity for 8K workloads, heavy rendering or high-refresh 4K gaming. The triple-fan cooler and 2595 MHz boost clock are engineered to sustain that performance inside a standard ATX form factor.

Upgrade threshold

This card replaces any GPU limited to 12GB or less of video memory, where texture streaming or compute buffers become the bottleneck. The jump is worth it when your current 384-bit or narrower interface cannot feed the 16384 CUDA cores at 21 Gbps, or when DirectX 12 Ultimate feature support is required for upcoming titles. A 450W thermal design power and single 16-pin connector mark the minimum power envelope for the upgrade.

Build integration

The 322 mm length fits most mid-tower cases while the ATX bracket occupies two slots. You need an 850W power supply with a native 16-pin cable or a certified adapter, plus PCI Express 4.0 x16 bandwidth to avoid interface saturation. Two HDMI 2.1 and two DisplayPort 1.4a outputs drive up to four displays at 7680 x 4320, freeing you from daisy-chain adapters or DSC compression compromises.
