White design for high-end builds

The ASUS ROG Strix GeForce RTX 4090 White OC Edition is a premium graphics card built on the NVIDIA Ada Lovelace architecture. It targets enthusiasts and creators who need 24GB of GDDR6X memory for 4K gaming, 3D rendering, or AI workloads. A factory overclock and robust power delivery support sustained high clocks in a distinctive white aesthetic.

Suits white-themed rigs with ample space

This card fits builders assembling a white workstation or gaming system with a case and power supply rated for a 3.5-slot cooler and high wattage. The physical size and power draw make it unsuitable for small-form-factor cases, modest PSUs, or any build where a neutral black or grey shroud is preferred.

24GB GDDR6X decides fit for memory-heavy work

The 24GB GDDR6X frame buffer is the specification that determines whether this model matches the workload. It enables large texture pools, high-resolution video timelines, and local LLM inference that smaller cards cannot hold. If the target application stays well below that capacity, a lower-tier GPU will cost less and consume less power.

Questions about this item

How do I verify the three Axial-tech fans and vapor chamber are keeping the GPU cool after installation?

Open GPU Tweak III and watch the temperature read-out while the three Axial-tech fans spin; the patented vapor chamber with milled heatspreader is designed to lower GPU temps under load.

What comes in the box and what must I source separately for the 3.5-slot card?

The card itself with its diecast shroud, frame and vented backplate is included; you must supply a case with enough clearance for the 3.5-slot design and a power supply with the required PCIe connectors.

Which display outputs does this 24GB GDDR6X model provide for my monitor?

It provides HDMI 2.1a and DisplayPort 1.4a connections driven by the RTX 4090 GPU with 24GB GDDR6X memory.
