Capacity and Interface

This is an MSI GeForce RTX 3090 Ventus 3X graphics card with 24GB of GDDR6X memory on a 384-bit bus. The GPU provides 10496 CUDA cores and a boost clock of 1725 MHz over a PCI Express 4.0 interface. It is built for workloads that need a large frame buffer and high memory bandwidth.

Suitability

The 24GB capacity suits 8K gaming, complex 3D rendering and large dataset compute where smaller buffers would bottleneck performance. A 350W TDP and a 750W PSU requirement mean builders with modest power supplies or compact cases should look at lower-power alternatives.

Deciding Specification

The single specification that decides fit is the 24GB GDDR6X memory paired with a 384-bit interface. Workloads that exceed 12GB buffers will run on this card without paging to system memory; workloads that fit in less memory gain no advantage from the extra capacity.

Highlights

Questions about this item

How loud and hot does the triple-fan Ventus cooler get when the RTX 3090 runs at its 350W TDP all day?

The card uses a triple-fan thermal design with TORX Fan 3.0, core heat pipes and a metal backplate with heatpipes to move heat away from the GPU and rear memory modules during sustained 350W loads.

My power supply only has a single 8-pin PCIe cable — will that run the RTX 3090 Ventus 3X OC?

No. The card requires two 8-pin power connectors and the manufacturer recommends a 750W PSU to meet the 350W thermal design power.

Will this PCI Express 4.0 card work in my older motherboard that only has PCI Express 3.0 slots?

Yes. The RTX 3090 Ventus 3X OC is backward compatible with PCI Express 3.0 slots, though it will operate at 3.0 speeds instead of 4.0.
