Refurbished RTX 5080 with GDDR7

This ASUS ROG Astral graphics card ships as a manufacturer-refurbished unit tested to full function. It carries the NVIDIA RTX 5080 GPU with 16GB of GDDR7 memory. The card targets enthusiasts who want high-end rendering performance and accept minor cosmetic signs of prior use.

Four-slot cooler and modern display outputs

The design occupies four expansion slots and relies on a fan-and-heatsink assembly to manage a 360-watt total graphics power rating. Three DisplayPort 2.1 connectors and two HDMI 2.1 ports support multiple monitors at up to 8K 4320p resolution. A PCI Express 4.0 x16 slot and an 850-watt power supply are required for installation.

PCIe 4.0 bandwidth ceiling and DLSS 4 reliance

The card operates on a PCI Express 4.0 x16 interface, which caps theoretical throughput at the 4.0 standard rather than the newer 5.0 spec. Heavy ray-tracing workloads lean on DLSS 4 upscaling to sustain frame rates, so native performance at maximum settings will be limited by the interface and the 16GB VRAM buffer. Buyers who need more memory or a second card for multi-GPU scaling should look elsewhere.

Questions about this item

What PCI Express standard does the ROG Astral RTX 5080 OC use and what bandwidth limit does it impose?

The card uses a PCI Express 4.0 x16 interface, which caps the link speed at the 4.0 generation rate between the GPU and the motherboard.

What physical space and power connectors are required to install this 4-slot graphics card?

It occupies four expansion slots and needs a power supply rated for at least 850 W to meet the 360 W total graphics power specification.

How is the card installed and which step is commonly missed when connecting the display outputs?

Seat the card firmly in the PCI Express 4.0 x16 slot, attach all required power cables, then connect monitors to the three DisplayPort 2.1 or two HDMI 2.1 ports — forgetting to plug the power cables is the frequent oversight.
