ASUS ROG Astral LC GeForce RTX 5090 32GB GDDR7 OC Edition – Liquid-Cooled GPU with 360mm AIO, DLSS4, PCIe 4.0, DP 2.1b, 32GB GDDR7 – ROG-ASTRAL-LC-RTX5090-O32G

ASUS ROG Astral LC GeForce RTX 5090 32GB GDDR7 OC Edition Description & Specifications:

The Ultimate Liquid-Cooled GPU for 8K Gaming, AI, and Extreme Workloads

The ASUS ROG Astral LC GeForce RTX 5090 32GB GDDR7 OC Edition redefines flagship performance with a hybrid liquid-air cooling system, 32GB GDDR7 memory, and NVIDIA DLSS4. Designed for enthusiasts, overclockers, and professionals, it delivers unparalleled 8K gaming, AI model training, and 3D rendering while maintaining whisper-quiet operation under load.

Key Features:

Hybrid Liquid-Air Cooling System

• 360mm All-in-One (AIO) Radiator: Triple 120mm ROG MF-12S ARGB fans with 4.8mm H₂O static pressure and 62.5 CFM airflow for maximum heat dissipation.
• Vapor Chamber GPU Block: Full-coverage nickel-plated copper block with microchannel fins and liquid metal TIM for 25% lower temps vs. air-cooled designs.
• Dual-Mode Cooling: Hybrid pump adjusts flow rate (1.5–3.0 L/min) based on load, reducing noise to 22 dBA at idle.

Unrivaled Performance

• 32GB GDDR7 Memory: 32 Gbps speeds on a 512-bit bus for 8K textures, AI datasets, and multi-display workflows.
• NVIDIA DLSS4 & Reflex: AI-upscaled 8K@144Hz gaming with sub-10ms latency in competitive titles like Cyberpunk 2077: Phantom Liberty.
• 18,432 CUDA Cores: 2.5x faster ray tracing and 3x AI inference vs. previous gen.

ROG Engineering Excellence

• Military-Grade VRM: 28+4 power phases with 100A DrMOS and TUF-rated capacitors for LN2 overclocking stability.
• ROG Aura Sync RGB: Customizable lighting with Armoury Crate integration, including GPU temp/load-reactive effects.
• PCIe 4.0 x16 Interface: Backward-compatible with PCIe 3.0/4.0 motherboards, optimized for 8K AV1 encoding/decoding.
