Overview
The ASUS ROG Astral GeForce RTX 5090 32GB GDDR7 White OC Edition is a high-performance desktop graphics card built on NVIDIA's GeForce RTX 5090 GPU architecture. It combines 32GB of GDDR7 video memory, a 512-bit memory interface, PCI Express 5.0 connectivity, and a factory-overclocked operating mode.
Part of the ASUS Republic of Gamers Astral series, this white graphics card features a quad-fan cooling design and addressable RGB lighting. It is designed for compatible desktop systems requiring substantial graphics memory, high-resolution display output, and GPU acceleration for demanding graphics workloads.
Graphics Processing and Memory
The NVIDIA GeForce RTX 5090 graphics processor features 21,760 CUDA cores and supports a maximum digital resolution of 7680 × 4320. The card includes 32GB of GDDR7 memory operating at 28 Gbps across a 512-bit memory interface.
ASUS specifies a default boost clock of 2580 MHz and an OC-mode clock of 2610 MHz. The available operating mode depends on the selected configuration and supported ASUS software.
Cooling and Physical Design
The ROG Astral cooling assembly uses four fans and a substantial heatsink to manage heat generated during graphics processing. The card occupies 3.8 expansion slots, so chassis clearance and motherboard expansion-slot layout should be checked before installation.
The white exterior is complemented by addressable RGB lighting with ASUS Aura Sync support. Compatible ASUS components can coordinate lighting effects through supported software.
Display Connectivity
The graphics card provides two native HDMI 2.1b ports and three native DisplayPort 2.1b ports. It supports HDCP 2.3 and can drive up to four displays simultaneously.
The maximum supported digital resolution is 7680 × 4320. Actual display resolution, refresh rate, and feature availability depend on the connected monitor, interface, cable, and configuration.
Key Features
- NVIDIA GeForce RTX 5090: Graphics processing with 21,760 CUDA cores and support for NVIDIA RTX technologies.
- 32GB GDDR7 memory: High-capacity video memory with a 512-bit interface and 28 Gbps memory speed.
- Factory-overclocked operation: ASUS specifies a 2610 MHz clock in OC mode and a 2580 MHz default boost clock.
- Quad-fan cooling: A four-fan thermal design integrated into a 3.8-slot graphics card.
- Multi-display connectivity: Two HDMI 2.1b ports and three DisplayPort 2.1b ports, with support for up to four simultaneous displays.
Applications
This graphics card is suited to high-performance desktop computing, advanced PC gaming, 3D rendering, GPU-accelerated creative applications, and workloads that benefit from substantial dedicated video memory. Its high-resolution display outputs also support compatible multi-monitor workstations.
Software-specific capabilities depend on the application, operating system, graphics driver, and supported NVIDIA technologies.
System Requirements and Compatibility
- Expansion interface: Requires a compatible PCI Express graphics slot. The card uses PCI Express 5.0.
- Power supply: ASUS recommends a 1000W power supply for a fully overclocked GPU and CPU system configuration.
- Power connection: The card uses one 16-pin auxiliary power connector.
- Chassis clearance: The card measures 357.6 × 149.3 × 76 mm and occupies 3.8 slots. Check the case's supported graphics card length, height, thickness, and power-cable clearance.
- Display equipment: Connected monitors and cables must support the desired resolution, refresh rate, and display features.
DC Supplies Product Note
Plan for both the card's physical size and its power requirements before selecting the rest of the system. The 357.6 mm card length and 3.8-slot thickness can restrict case and expansion-slot choices. Follow ASUS installation guidance for the 16-pin power connection, and select a suitable power supply based on the complete system configuration rather than GPU requirements alone.
