32GB GDDR7 for 8K workloads

The ASUS ROG Astral GeForce RTX 5090 delivers 32GB of GDDR7 memory across a 512-bit interface. It targets creators and enthusiasts who need maximum frame-buffer capacity for 8K gaming, large-model inference or complex 3D scenes. The white finish suits clean build aesthetics.

Upgrade from older flagship GPUs

Moving to this card adds PCI Express 5.0 bandwidth, 21760 CUDA cores and 28 Gbps memory speed. The jump is worth it when current hardware limits texture streaming, ray-tracing throughput or VRAM headroom in the latest titles. A 1000W power supply and a 16-pin connector are required.

Sustained load with triple-fan cooling

Under continuous load the 575W thermal design is managed by a triple-fan cooler occupying 3.8 slots. The card maintains its 2580 MHz boost clock while exhausting heat through the full-length heatsink. HDMI 2.1b and DisplayPort 2.1a outputs drive up to four 7680x4320 displays without throttling.

Questions about this item

Will the 357.6 mm length and 3.8-slot width fit my case and motherboard spacing?

The card measures 357.6 mm long and occupies 3.8 slots, so verify your chassis maximum GPU length and that three full expansion slots plus the extra clearance are free.

Does the single 16-pin connector plug straight in or do I need an adapter for my 1000W PSU?

Connect the 16-pin cable directly from a native ATX 3.0 supply or use the supplied adapter with two 8-pin cables, seating the connector fully until the latch clicks.

How often should I clean the triple-fan cooler on this 575W TDP card?

Blow dust from the three fans and heatsink fins every three to six months to maintain airflow for the 575W thermal design.
