The ASUS ROG Astral LC GeForce RTX 5090 OC Edition features a custom-built 360mm AIO liquid cooling system with an extra-thick 38mm radiator and three performance-grade fans. A full-coverage copper cold plate directly cools all heat-generating components, resulting in up to 30% better performance than traditional air cooling. Additionally, a low-profile heatsink and axial-tech fan quietly exhaust heat from the power delivery system, ensuring long-term reliability.
Advanced 80-amp MOSFETs enable high overclocking potential while maintaining acoustic and thermal balance. A phase-change thermal pad boosts heat transfer efficiency to sustain performance under pressure.
To ensure maximum stability and GPU-first power delivery, the ASUS ROG Thor III 1600W Titanium Gaming Power Supply is the perfect companion. With GPU-First architecture, it enhances voltage stability by up to 45%, delivering consistent power during intensive gaming and overclocking scenarios, unlocking the full potential of the RTX 5090 platform.
