ASUS ROG Strix RTX 4080 OC Edition graphics card

This ASUS ROG Strix RTX 4080 OC Edition graphics card targets enthusiasts who need high frame rates at 4K resolution. It ships with 16GB of GDDR6X memory connected through a PCIe 4.0 interface. The factory overclock pushes core frequencies beyond reference specifications for extra headroom in demanding titles. A 3.5-slot cooler assembly handles the thermal load of the Ada Lovelace architecture.

Axial-tech fans and vapor chamber under sustained

Three Axial-tech fans scaled up for 23% more airflow feed a massive fin array across the 3.5-slot design. A patented vapor chamber with a milled heatspreader contacts the GPU die directly to spread heat quickly. Diecast shroud, frame and backplate add rigidity while vented surfaces let hot air escape the chassis. Digital power control with high-current stages and 15K capacitors maintains stable voltage during extended gaming sessions.

PCIe 4.0 and display interface practical limits

The card communicates over a PCIe 4.0 x16 link, so bandwidth matches other Ada Lovelace GPUs on the same platform. Video output relies on HDMI 2.1a and DisplayPort 1.4a for 4K high-refresh or 8K signals. GPU Tweak III software provides performance tweaking, thermal controls and system monitoring in one utility. The 16GB GDDR6X frame buffer sets the ceiling for texture-heavy workloads at ultra settings.

Questions about this item

How loud and hot does the Strix 4080 run under sustained load with its 3.5-slot cooler and 23% airflow gain?

The 3.5-slot design pairs a patented vapor chamber with milled heatspreader and three scaled-up Axial-tech fans to move 23% more air, keeping GPU temperatures lower during all-day operation.

What power connectors and PSU headroom does the ROG-STRIX-RTX4080-O16G-GAMING need to run?

Digital power control with high-current power stages and 15K capacitors feeds the Ada Lovelace GPU, so a quality ATX 3.0 or equivalent supply with native 12VHPWR or dual 8-pin cables is required.

Will the HDMI 2.1a and DisplayPort 1.4a ports on this 4080 drive my current 4K display without adapters?

The card provides HDMI 2.1a and DisplayPort 1.4a outputs, matching the inputs on most modern 4K panels for direct connection.
