ROG Strix RTX 4080 SUPER Gaming Card

The ASUS ROG Strix GeForce RTX 4080 SUPER Gaming graphics card targets enthusiasts who need high frame rates at 4K resolution. It ships with 16GB GDDR6X memory and connects through a PCIe 4.0 interface. A boost clock of 2580 MHz supports demanding rasterised and ray-traced workloads. The 3.5-slot cooler uses a patented vapor chamber and three Axial-tech fans.

Vapor Chamber Cooling Under Load

The milled heatspreader and vapor chamber move heat away from the GPU die during extended sessions. Three scaled Axial-tech fans deliver 23% more airflow across a massive fin array. A diecast shroud, frame and vented backplate add rigidity while allowing hot air to escape. Digital power control with high-current stages and 15K capacitors maintains stable voltage when clocks stay elevated.

PCIe 4.0 and Display Output Limits

The card operates on a PCIe 4.0 x16 link, so bandwidth tops out at the 4.0 specification. External displays connect through HDMI 2.1a and DisplayPort 1.4a, limiting single-cable refresh rates to those standards. Auto-Extreme automated manufacturing aims to improve long-term reliability. GPU Tweak III software provides manual control over clocks, fan curves and thermal targets.

Questions about this item

How much heat and noise do the three Axial-tech fans and 3.5-slot vapor-chamber cooler produce under sustained load?

The triple Axial-tech fans are scaled for 23 % more airflow, and a patented vapor chamber with milled heatspreader feeds a massive fin array, so temperatures stay lower while acoustic output remains controlled during long sessions.

What power connectors and PSU headroom does the 16 GB GDDR6X card require?

Digital power control with high-current stages and 15K capacitors draws power through the standard PCIe 4.0 interface and supplemental PCIe power cables; ensure your supply has the needed 8-pin or 12VHPWR connectors and sufficient wattage headroom.

Will the HDMI 2.1 and DisplayPort 1.4 outputs drive my existing 4K high-refresh monitor without adapters?

Yes — the card provides HDMI 2.1a and DisplayPort 1.4a ports, so a 4K high-refresh display connects natively using its own cable.
