ROG Astral RTX 5090 Edition 20

The ASUS ROG Astral GeForce RTX 5090 Edition 20 is a PCI Express 5.0 graphics card built on the NVIDIA Blackwell architecture with 32GB of GDDR7 memory. It targets creators and enthusiasts who need 21760 CUDA cores and AI-ready performance for 7680 x 4320 workloads.

Installation and common issues

The card occupies 4.7 slots and measures 361 mm in length, so verify case clearance before fitting. A 1200W power supply is recommended; the detachable GC-HPWR adapter supports both standard and BTF motherboards, but forgetting to connect both the gold finger and the 12V-2x6 cable limits the board to a single power source.

Practical limits of PCIe 5.0 and DisplayPort 2.1

PCI Express 5.0 doubles the lane bandwidth of the previous generation, yet real-world throughput still depends on motherboard trace quality and CPU lane allocation. The three DisplayPort 2.1b outputs and two HDMI 2.1b ports can drive four monitors at 7680 x 4320, though sustained 28 Gbps memory speed requires adequate airflow across the quad-fan cooler and vapor chamber.

Questions about this item

How do I confirm the card is running at its intended boost clock after installation?

Use GPU monitoring software to verify the core reaches 2760 MHz in OC mode or 2730 MHz in default mode under load.

What accessories are included and what must I supply separately?

The box contains a detachable 6.67-inch AMOLED display, glass backplate, GC-HPWR adapter, and graphics card holder. You must provide a 1200W power supply with a 12V-2x6 cable.

Which specification difference should guide my choice between available versions?

This model is defined by its 32GB GDDR7 memory on a 512-bit interface, 21760 CUDA cores, and dual power input supporting up to 800W.
