Our verdict

A well-built high-end card on paper, with reinforced construction and strong cooling, though buyers should confirm PSU wattage and case clearance since there's no review history yet to lean on.

Overview

A GeForce RTX 5080 graphics card in Asus's TUF Gaming line with 16GB of GDDR7 memory, factory overclocked, built on the Blackwell architecture with a 3.6-slot triple-fan cooler.

TUF Gaming is Asus's durability-focused tier, so the emphasis here is reinforced components and a protective PCB coating rather than the styling of Asus's ROG line. It needs a minimum 850W power supply with a 12V-2x6 (12VHPWR) connector, and at 348mm long and 3.6 slots wide, case clearance is worth checking before buying since it's a genuinely large card.

GeForce RTX 5080, 16GB GDDR7, Blackwell architecture
3.6-slot cooler with triple Axial-tech fans
Requires 850W+ PSU, 12V-2x6 (12VHPWR) connector
2700 MHz boost clock, 2730 MHz in OC mode

Who it's for

Suits builders with a spacious case, an 850W or larger PSU, and a want for high-end 4K or high-refresh 1440p gaming performance. Not a fit for compact or small-form-factor builds, or anyone without a PSU that supports the required 12VHPWR connector.

Pros and cons

Pros

16GB GDDR7 memory for high-end gaming
Large 3.6-slot cooler with three Axial-tech fans
Reinforced components and protective PCB coating
GPU Tweak III software for monitoring and tuning

Cons

Requires an 850W+ PSU with a 12VHPWR connector
Large 348mm, 3.6-slot size needs a big case

Performance notes

The card runs on Nvidia's Blackwell architecture with DLSS 4 support, and the triple Axial-tech fan array is sized for the 3.6-slot heatsink to move heat off a card drawing meaningfully more power than previous generations. A phase-change thermal pad on the GPU die replaces standard thermal paste, which Asus positions as holding up better under sustained heavy loads. Factory clocks run at 2700 MHz boost by default with a 2730 MHz OC mode available through GPU Tweak III software.
