ROG Strix GeForce RTX 4080 16GB GDDR6X

The ASUS ROG Strix GeForce RTX 4080 OC Edition is a refurbished graphics card built on the NVIDIA Ada Lovelace architecture. It connects via PCI Express 4.0 and provides 16GB of GDDR6X memory across a 256-bit interface. The card features a triple-fan cooler with a patented vapor chamber and a 3.5-slot design for thermal management.

Buyers targeting 4K gaming or GPU compute with

This card suits users who need 16GB GDDR6X for high-resolution textures and large frame buffers at 7680 x 4320 output. It requires a 750W power supply and a 16-pin connector, plus clearance for a 358 mm long, 3.5-slot thick ATX form factor. Builders with smaller cases or lower-wattage PSUs should consider different models.

16GB GDDR6X on 256-bit bus decides fit

The single specification that determines suitability is the 16GB GDDR6X memory on a 256-bit interface. This capacity and bandwidth combination enables 4K and multi-monitor workloads that 12GB or narrower-bus cards cannot sustain. Verify case length, slot width, and PSU requirements before purchase.

Questions about this item

What comes in the box and do I need to buy a 16-pin power cable separately?

The card includes a 16-pin power connector; a compatible 750W PSU with that cable is required but not supplied

Which clock speed should I expect when gaming — the 2625 MHz game clock or the 2655 MHz boost clock?

The 2625 MHz game clock is the typical sustained frequency under load; 2655 MHz is the peak boost reached in lighter bursts

What does the 320 W thermal design power mean for my power supply and case airflow?

A 750W PSU is recommended and the 3.5-slot triple-fan cooler needs adequate case clearance for the 358 mm length
