MSI Suprim X GeForce RTX 4080 16GB

The MSI Suprim X GeForce RTX 4080 is a graphics card built for enthusiasts who need high frame rates at 4K resolution. It uses the NVIDIA GeForce RTX 40 Series GPU with 9728 CUDA cores and connects via a PCI Express 4.0 interface. The card supports DirectX 12 Ultimate and OpenGL 4.6 for modern rendering workloads. It is designed for users who want premium build quality and strong rasterisation performance.

16GB 256-Bit GDDR6X Memory

The card carries 16GB of GDDR6X memory across a 256-bit bus, giving ample bandwidth for 4K gaming and creative applications. This capacity handles large texture packs, high-resolution assets and multi-monitor setups without paging to system memory. The frame buffer becomes a limit only in extreme compute workloads or future titles that demand more than 16GB of VRAM. For current 4K and high-refresh 1440p gaming the memory size is comfortable headroom.

320W TDP and 850W PSU Requirement

The thermal design power is rated at 320W and MSI recommends a power supply of at least 850W. This figure decides whether the card fits an existing build or forces a PSU upgrade. The triple-fan cooler is engineered to dissipate this heat load, but the power draw itself is the fixed constraint. Check your PSU wattage and available PCIe power connectors before purchase.

Questions about this item

Will the PCI Express 4.0 interface on this RTX 4080 work with my current PCIe 3.0 motherboard?

Yes, the card is backward compatible with PCIe 3.0 slots and will run at PCIe 3.0 speeds without any configuration changes.

How can I verify the 9728 CUDA cores and 16GB GDDR6X memory are detected correctly after installation?

Open NVIDIA Control Panel or GPU-Z; both will list the full 9728 CUDA cores and 16GB GDDR6X on a 256-bit bus.

Does the box include the 12VHPWR power adapter or must I buy a native 12VHPWR PSU cable separately?

The package contains the graphics card, a 12VHPWR adapter for traditional 8-pin cables, and a support bracket; no native 12VHPWR PSU cable is included.
