TUF Gaming RTX 5080 16GB GDDR7

The ASUS TUF-RTX5080-O16G-GAMING is a PCI Express 5.0 graphics card built on the NVIDIA Blackwell architecture. It delivers 10752 CUDA cores and 16GB of GDDR7 memory on a 256-bit bus for 4K gaming and creative workloads. The factory overclocked design targets enthusiasts who want high frame rates without moving to a larger chassis. Military-grade components are used throughout the power delivery.

Installation notes 3.6-slot ATX card

The card measures 348 mm long, 146 mm tall and 72 mm thick, occupying 3.6 expansion slots in an ATX case. Verify that your case has the clearance and that your power supply can deliver 850W with the required connectors. The 360W thermal design power means adequate case airflow is essential. A common issue is forgetting to connect all power cables before the first boot.

Sustained load behaviour 360W TDP

Under continuous load the 360W TDP keeps the cooler working at a steady rate rather than spiking briefly. The large heatsink and vapour chamber move heat away from the GPU core and memory modules over long sessions. Fan curves ramp gradually to maintain temperature targets without sudden speed changes. This stability helps prevent throttling during extended rendering or gaming periods.

Questions about this item

How can I confirm the card is running at its OC clock after installation?

Use GPU-Z or ASUS GPU Tweak III to verify the boost clock exceeds the reference 5080 specification and that memory reports 960 GB/sec bandwidth on the 256-Bit GDDR7 interface.

What comes in the box and what must I source separately?

The package contains the TUF-RTX5080-O16G-GAMING card, a quick-start guide and a warranty card; you must supply an 850W PSU with enough PCIe power connectors for the 360W TDP and a case that clears 348 mm length and 3.6-slot width.

Should I choose the 16 GB GDDR7 version or a different capacity?

This model exists only as a 16 GB GDDR7 variant with 10752 CUDA cores; no other memory size or memory type is offered for the TUF-RTX5080-O16G-GAMING.
