Overview
The ASUS ROG Astral GeForce RTX 5080 16GB GDDR7 OC Edition is a high-performance desktop graphics card designed for gaming, graphics-intensive applications, and creative workloads. Based on the NVIDIA GeForce RTX 5080 GPU and Blackwell architecture, it combines dedicated graphics processing, high-bandwidth GDDR7 memory, and advanced cooling hardware in a factory-overclocked design.
This model features 10,752 CUDA cores, 16GB of GDDR7 video memory, and support for PCI Express 5.0. Its ROG Astral cooling system incorporates four fans and a vapor chamber to manage heat during demanding workloads.
Graphics Performance and Memory
The GPU operates at a default boost clock of 2,760 MHz, with an OC mode clock of 2,790 MHz. The 256-bit memory interface and 30 Gbps memory speed support graphics-intensive workloads, high-resolution gaming, and GPU-accelerated creative applications.
NVIDIA technologies supported by the RTX 50 Series platform include DLSS 4, fourth-generation ray tracing cores, fifth-generation Tensor Cores, and NVIDIA Reflex 2. Actual performance depends on the application, system configuration, drivers, and selected settings.
Cooling and Thermal Design
The ROG Astral cooling assembly uses a four-fan design, a patented vapor chamber, and a phase-change GPU thermal pad. The heatsink and fin arrangement are engineered to dissipate heat from the GPU and memory during sustained operation.
- Four-fan cooling design with Axial-tech fans.
- Patented vapor chamber for heat transfer.
- Phase-change GPU thermal pad.
- Protective PCB coating designed to help guard against moisture and debris.
- Die-cast metal frame, shroud, and backplate construction.
Display Connectivity
The card provides five display outputs: two native HDMI 2.1b ports and three native DisplayPort 2.1b ports. It supports HDCP 2.3 and a maximum digital resolution of 7680 × 4320. Up to four displays can be supported simultaneously, subject to the operating environment and display configuration.
Display selection should account for the monitor's resolution, refresh rate, supported interface, and cable requirements. The graphics card's output connectors and the monitor's input connectors must be compatible.

System Compatibility and Installation
This graphics card is designed for compatible desktop systems with a PCI Express graphics slot. Before installation, check the motherboard and chassis clearances, available power connections, system power supply capacity, and airflow.
ASUS recommends an 850W power supply for this graphics card. The card uses one 16-pin power connector. The power supply and cable arrangement must be appropriate for the installed system and comply with the manufacturer's connection requirements.
The card measures 357.6 × 149.3 × 76 mm and occupies 3.8 slots. Check the available case length, expansion-slot clearance, and space around the card before purchasing. The large cooler may restrict access to adjacent expansion slots.
DC Supplies Product Note
Chassis clearance and power delivery are important considerations for this particular model. Its 357.6 mm length and 3.8-slot thickness require a case with sufficient graphics-card clearance. ASUS's 850W power supply recommendation is intended for a fully overclocked GPU and CPU system configuration; actual system requirements depend on the complete component selection. Confirm the power supply's supported 16-pin connection and cable requirements before installation.
