ASUS ROG-STRIX-RTX4090-O24G-WHITE graphics card

White RTX 4090 for high-end builds

The ASUS ROG Strix GeForce RTX 4090 White OC Edition is a graphics card built for enthusiasts who need maximum frame rates at 4K and 8K. It uses the NVIDIA Ada Lovelace architecture with 16384 CUDA cores and 24GB of GDDR6X memory on a 384-bit bus. The PCIe 4.0 interface connects to modern platforms without bottlenecking the GPU. This refurbished unit delivers the same specification as a new card.

Sustained load with 3.5-slot cooling

Under continuous load the triple Axial-tech fans move 23% more air through a patented vapor chamber and a massive fin array. The 3.5-slot design allows the heatsink to absorb the 450W thermal design power without throttling the 2610 MHz game clock. Digital power control with high-current stages and 15K capacitors keeps voltage stable during long rendering or gaming sessions. A vented diecast shroud, frame and backplate add rigidity while letting hot air escape the chassis.

24GB GDDR6X decides 8K viability

The single specification that determines whether this card fits your workflow is the 24GB GDDR6X frame buffer paired with a 21 Gbps effective memory clock. That capacity and bandwidth let the GPU hold full-resolution 8K textures and multiple high-refresh displays without swapping to system memory. If your workload stays below that threshold a smaller buffer may suffice; above it the 384-bit interface becomes essential.
