ASUS ROG Strix RTX 4090 BTF OC graphics card

Refurbished RTX 4090 for high-end builds

This ASUS ROG Strix RTX 4090 BTF OC is a manufacturer-refurbished graphics card with 24 GB GDDR6X memory. ASUS has tested the unit and confirms full functionality, though slight cosmetic wear may be present. It ships in plain packaging and connects via a PCI Express 4.0 x16 slot. The card targets enthusiasts who want flagship rasterisation and AI performance without buying new.

Thermals and power at stock settings

The triple-slot cooler uses fans and a heatsink to manage a 450 W total graphics power rating. At the 2.23 GHz base clock and 1.31 GHz VRAM clock the card runs within its thermal envelope while driving up to four displays through three DisplayPort 1.4 outputs and one HDMI 2.1 port. ASUS recommends an 850 W power supply for stable operation.

Behaviour under sustained load

When the GPU boosts to 2.52 GHz during extended gaming or rendering sessions, the cooling assembly continues to dissipate heat without throttling the 24 GB frame buffer. DLSS 3 frame generation and ray tracing workloads remain consistent because the power delivery and memory bandwidth are unchanged from a new unit. Buyers who need a warranty longer than the refurbished term or who require pristine aesthetics should consider other options.
