Product identity

The ASUS ROG Strix GeForce RTX 3090 in white delivers 24GB of GDDR6X memory on a 384-bit bus with 10496 CUDA cores. It targets creators and researchers who need large frame buffers for 3D rendering, video editing or AI workloads.

Who should buy and who should pass

This card suits professionals who regularly exceed 12GB VRAM limits and can provide a 750W power supply with three 8-pin connectors. Gamers focused only on 1440p or 4K raster performance should look at smaller, cooler and cheaper alternatives.

Deciding specification

The 24GB GDDR6X frame buffer combined with a 384-bit memory interface is the single specification that decides fit. If your workload saturates 12GB buffers, this capacity and bandwidth combination justifies the power and thermal demands.

Questions about this item

What case clearance and power supply capacity does the triple-fan RTX 3090 with 384-bit GDDR6X require?

The card occupies a 3-slot footprint and needs a chassis that can fit a 3-fan cooler; the maker recommends a 750 W PSU to support the 850 W thermal design power.

How do I connect the three 8-pin power cables on this PCI Express 4.0 board without missing a connector?

Plug all three 8-pin cables from the power supply into the card before tightening the rear bracket; each connector must seat fully or the GPU will not start.

When should I plan to renew the thermal interface on the GeForce RTX 3090 with 10496 CUDA cores?

Refresh the paste every couple of years or if core temperatures climb noticeably above the 1860 MHz gaming-mode baseline under load.
