Our take on the ASUS ROG Astral NVIDIA GeForce RTX 5080 16GB GDDR7 OC Graphics Card

The ROG Astral is ASUS's flagship take on the GeForce RTX 5080, built around a 4-fan cooler, a vapor chamber and a phase-change thermal pad on a 3.8-slot body. It ships factory overclocked with 16GB of GDDR7 on a 256-bit bus, 10,752 CUDA cores and DLSS 4 support, so it targets high-refresh 1440p and 4K gaming with ray tracing on. Against thinner two- and three-fan RTX 5080 cards it runs cooler and quieter under load, but it is one of the largest and heaviest options and needs a big case and an 850W PSU. Owners rate it highly for thermals and build, and the main complaints are its size and the 16GB frame buffer at 4K.

Pros
  • Quad-fan cooler with vapor chamber keeps GPU temperatures low
  • Runs quietly for its performance class
  • Factory overclocked with strong power delivery
  • Metal frame, GPU Guard bracket and die-cast shroud feel premium
  • Two HDMI 2.1b and three DisplayPort 2.1a outputs
Cons
  • 3.8-slot, roughly 5.9-inch-tall body blocks adjacent slots and needs a roomy case
  • Heavy card; a support bracket is advisable
  • 16GB of VRAM is the same as cheaper RTX 5080s and tight for heavy 4K texture work
  • Needs an 850W PSU and a 16-pin connector
  • Little headroom for overclocking beyond the factory tune

Questions and answers

Is the ROG Astral RTX 5080 worth it over a cheaper RTX 5080?
If you want the coolest, quietest RTX 5080 and have the case space, yes. Cheaper cards use the same GPU and 16GB of memory, so you pay for cooling, build and the factory overclock, not more frames at stock settings.
Will it fit my case?
It is a 3.8-slot card about 5.9 inches tall, so check your case's GPU clearance and slot layout. A mid-tower with a front-mounted radiator may not leave enough room.
What power supply do I need?
ASUS recommends an 850W PSU, and the card uses a single 16-pin connector. Use the adapter or native 12V-2x6 cable from your PSU and seat it fully.
How does it compare with the RTX 4080 Super?
It is faster, especially with DLSS 4 and ray tracing, and adds the newer DisplayPort 2.1a outputs. The jump is modest at 1440p but clearer at 4K with ray tracing on.
Does it support DLSS 4 and multi-frame generation?
Yes. It is built on the Blackwell architecture, so it supports DLSS 4 including multi-frame generation in supported games.
What is in the box?
The card, a 16-pin power adapter, and ASUS's GPU Guard bracket hardware. A support bracket for the card's weight is worth adding if your case does not include one.
Where is the ASUS ROG Astral NVIDIA GeForce RTX 5080 16GB GDDR7 OC Graphics Card cheapest?
