TUF Gaming GeForce RTX 4080 16GB

The ASUS TUF Gaming GeForce RTX 4080 is a full-size ATX graphics card built for enthusiasts who need high frame rates at 4K. It uses the NVIDIA Ada Lovelace architecture with 16GB of GDDR6X memory and a triple-fan cooler housed in a metal exoskeleton. The card occupies 3.65 slots and measures 348.2mm long.

16-Pin power connector and 750W PSU requirement

This model draws up to 320W through a single 16-pin connector, so the system power supply must deliver at least 750W. The PCB uses military-grade capacitors rated for 20K hours at 105C, and the dual ball fan bearings are rated to last twice as long as sleeve designs. Axial-tech fans provide 23% more airflow than the previous layout.

16GB GDDR6X memory with PCIe 4.0 bandwidth

The 16GB frame buffer handles 4K gaming, heavy texture mods and multi-monitor workloads across four displays at up to 7680 x 4320 resolution. Three DisplayPort 1.4a outputs and two HDMI 2.1 ports drive high-refresh panels without adapters. GPU Tweak III software exposes clock tuning, fan curves and real-time monitoring for the 2505 MHz game clock and 2535 MHz boost clock.

Questions about this item

What does the 2535 MHz boost clock mean once the card is installed in my system?

It is the maximum GPU frequency the card targets under load when power and temperature headroom allow. Actual sustained clocks depend on your case airflow and the 320 W power limit.

How does the PCIe 4.0 interface affect real-world throughput?

The card runs at PCIe 4.0 x16, doubling the lane bandwidth of PCIe 3.0. In current games the difference is small; it matters more for compute workloads that saturate the bus.

Will the 348 mm length and 3.65-slot thickness fit my ATX case?

Measure from the motherboard PCIe bracket to the nearest obstruction — drive cage, radiator, or side panel. You need at least 348 mm clear length and vertical space for a 3.65-slot cooler.
