ROG Astral RTX 5090 32GB GDDR7

The ASUS ROG Astral GeForce RTX 5090 is a 32GB graphics card built on the NVIDIA GeForce RTX 50 Series architecture with 21760 CUDA cores. It targets enthusiasts and professionals who need maximum frame buffers for 4K gaming, high-resolution content creation and AI workloads. The card connects via PCI Express 5.0 and outputs to four displays through two native HDMI 2.1b and three native DisplayPort 2.1a ports. A white shroud and triple-fan cooler complete the design.

Power and space requirements

Before ordering, confirm your power supply delivers at least 1000W and provides a single 16-pin connector for the 575W thermal design power. The card occupies 3.8 expansion slots and measures 357.6 mm in length, so verify case clearance and motherboard spacing. A PCI Express 5.0 slot is required to utilise the full interface bandwidth.

Sustained-load behaviour

Under continuous load the 2580 MHz boost clock and 28 Gbps GDDR7 memory maintain high throughput across the 512-bit bus for extended rendering or compute sessions. The triple-fan cooler is engineered to dissipate 575W over long periods without thermal throttling. Stable output relies on adequate case airflow and a power supply that meets the 1000W recommendation.

Questions about this item

What comes in the box and what must be bought separately?

The card includes the triple-fan cooler and a 16-pin power adapter; you must supply a 1000W PSU and a PCIe 5.0 slot.

Which version should I choose for 4K gaming versus AI workloads?

This single 32GB GDDR7 model with 21760 CUDA cores covers both high-resolution gaming and large-model inference.

What does the 2580 MHz boost clock mean once the card is installed?

It is the peak GPU frequency under load; actual clocks will vary with temperature, power limit and the workload you run.
