Built for 4K gaming and creative work

The ASUS TUF RTX 4080 Super OC delivers 16 GB of GDDR6X memory on a PCI Express 4.0 x16 interface. It targets enthusiasts who need high frame rates at 4K resolution and reliable throughput for rendering or video workloads. The factory overclock adds extra headroom for demanding titles.

Thermals and power in daily use

The TUF cooling array moves heat away from the GPU so temperatures stay controlled during extended sessions. Fan curves keep acoustic output low at idle and moderate under load. The card draws power through standard connectors and operates within the RTX 4080 SUPER envelope.

Bundled software and accessories

GPU Tweak III provides a unified dashboard for clock offsets, fan curves and real-time monitoring. A metal backplate stiffens the PCB and protects the rear components. The package includes a support bracket that prevents sag in horizontal mounts.

Questions about this item

How do I install the card into a PCI Express 4.0 x16 slot and what step is often missed?

Align the card with the PCI Express 4.0 x16 slot, press firmly until the retention latch clicks, then connect the required power cables from the PSU; the step people miss is forgetting to plug in all power connectors before booting.

What maintenance will the 16GB GDDR6X model need over time?

Dust the heatsink and fans every few months with compressed air, check that fan blades spin freely, and replace thermal paste only if temperatures rise unusually after several years of use.

What limit appears first during sustained loads on the RTX 4080 SUPER?

The GPU temperature target is reached first, causing the boost clock to throttle back until the cooling system catches up.
