16GB GDDR6X 4K Ready

This MSI RTX 4080 VENTUS 3X delivers 16GB GDDR6X memory on a 256-Bit bus with 9728 CUDA cores for 4K gaming and creative workloads. The triple-fan cooler handles the 320W TDP across a 322mm length. It connects via PCI Express 4.0 and requires a 750W PSU with one 16-Pin power connector.

Upgrade from 8GB or 12GB cards

Moving to 16GB GDDR6X removes VRAM bottlenecks in modern 4K titles and heavy texture workloads. The 9728 CUDA cores and DirectX 12 Ultimate support lift frame rates where 8GB or 12GB frame buffers force texture streaming compromises. The jump is worth it when your current card hits memory limits before GPU utilisation peaks.

Fits standard ATX builds

The 322mm card fits most mid-tower cases and leaves room for front-mounted radiators. One HDMI 2.1 and three DisplayPort 1.4a outputs drive up to four 7680x4320 displays. The 750W PSU recommendation covers the 320W TDP with headroom for CPU and peripherals. PCI Express 4.0 provides full bandwidth on current platforms.

Questions about this item

How much case clearance does the 322 mm Ventus 3X card need?

The card measures 322 mm long, so your chassis must provide at least that much clear space from the rear bracket to any drive cage or front panel.

Which power connector does the 320 W RTX 4080 require and what mistake should I avoid?

It uses a single 16-pin connector; plug the native 12VHPWR cable from the PSU instead of daisy-chaining two 8-pin adapters, which can melt under load.

When should I plan to clean the triple-fan cooler or replace thermal paste on this 16 GB model?

Dust the three fans every six to twelve months with compressed air; repaste the GPU die only if temperatures rise noticeably after a few years of heavy use.
