Our take on the ASUS Prime GeForce RTX 5080 16GB GDDR7 OC Edition Graphics Card

The ASUS Prime GeForce RTX 5080 OC is a 16GB GDDR7 graphics card built on NVIDIA's Blackwell architecture, aimed at 4K gaming and local AI work. It uses a 2.5-slot body with three Axial-tech fans, a vapor chamber and a phase-change thermal pad, and ASUS rates it SFF-Ready for compact builds. Its OC mode boost of 2685 MHz is a mild step over the reference card, so the draw is cooling and size rather than raw speed. Owners rate it highly, and it sits below ASUS's TUF and ROG models on extras while keeping the same GPU and 16-pin power connector.

What reviewers say

  • 4.8 / 528 ratings

Owners rate it 4.8 out of 5 and mostly praise its cooling and how easily it fits smaller cases. Complaints center on the power supply requirement and the single 16-pin connector.

What people mention
  • CoolingPraisedOwners say the vapor chamber and three fans keep GPU temperatures low under sustained load.
  • SizePraisedBuyers report the 2.5-slot body fits cases where larger cards will not.
  • NoisePraisedFans stay quiet at moderate loads, according to owners.
  • Power drawMixedSome note the 850W recommended supply and single 16-pin connector as a build constraint.
  • OverclockMixedA few say the factory OC is small enough to be barely noticeable over reference clocks.

About the ASUS Prime GeForce RTX 5080 16GB GDDR7 OC Edition Graphics Card

The ASUS Prime GeForce RTX 5080 OC Edition is a graphics card built on the NVIDIA Blackwell architecture with 16GB of GDDR7 memory. It supports DLSS 4 and ray tracing. It is SFF-Ready, so it is compatible with small-form-factor builds.

Three Axial-tech fans cool the card. They have a smaller fan hub, longer blades and a barrier ring to increase downward air pressure. The shroud, heatsink and heat pipes are arranged so the fans can use airflow from the chassis side panel. A vapor chamber moves heat away from the GPU. A phase-change GPU thermal pad improves heat transfer and helps the card hold up under heavy loads.

The card connects through PCI Express 5.0 and draws power through one 16-pin connector. It has three DisplayPort 2.1 ports and one HDMI 2.1 port, and it can drive up to six displays at a maximum resolution of 8K.

Questions and answers

Is the RTX 5080 worth it over the RTX 4080?
It brings DLSS 4, GDDR7 memory and PCIe 5.0, so it is the newer platform. Whether the step up matters depends on whether you use DLSS 4 and ray tracing heavily.
Will it fit a small-form-factor case?
ASUS lists it as SFF-Ready at 306 mm long, 126 mm wide and about 2.5 slots thick. Check your case's clearance for those figures before buying.
What power supply do I need?
ASUS recommends an 850W unit with a 16-pin connector. A weaker supply may trip under heavy gaming loads.
How many monitors can it drive?
Up to six displays through three DisplayPort 2.1 ports and one HDMI 2.1 port, at resolutions up to 8K.
Does it support DLSS 4?
Yes. It runs DLSS 4 and hardware ray tracing on the Blackwell architecture.
What is in the box?
The card itself. A 16-pin adapter is not listed, so confirm your power supply has the native connector.
