The short version

The ROG Astral OC Edition pairs the 32 GB GeForce RTX 5090 with ASUS's first four-fan ROG cooler, a vapor chamber and a small factory overclock. It is the fastest class of gaming GPU available, but at 3.8 slots and about 358 mm it needs a very large case and a 1000 W class power supply. It suits builders chasing maximum 4K performance and cooling headroom who are comfortable with a halo-tier premium.

Pros

  • Quad-fan design with vapor chamber and phase-change GPU thermal pad
  • Factory boost clock of 2580 MHz, with 2610 MHz in OC mode
  • Two native HDMI 2.1b and three DisplayPort 2.1b outputs
  • Bundled card holder and a 1-to-4 power adapter cable

Cons

  • 3.8-slot, 357.6 mm body demands a very large case and clearance
  • Needs a 1000 W power supply and a 16-pin connector with sufficient headroom
  • 575 W class power draw and heat output
  • Halo-tier pricing for a modest factory overclock

Best for

  • Maximum-performance 4K and AI workstations
  • Large cases with strong airflow

What reviewers and owners say

  • Tom's Hardware

    Mixed
