ASUS ROG Astral LC GeForce RTX 5090 32GB OC Edition Nvidia Graphic Card

The ASUS ROG Astral LC GeForce RTX 5090 32GB OC Edition is the flagship liquid-cooled graphics card in ASUS's premium ROG Astral lineup. Engineered for enthusiasts who demand the highest levels of thermal control and overclocking headroom, it integrates a dedicated 360mm all-in-one liquid cooling solution directly into the card itself — a design that sets it apart from conventional air-cooled alternatives. At its core sits NVIDIA's GeForce RTX 5090 GPU, backed by 21,760 CUDA cores, 32GB of GDDR7 video memory running at 28 Gbps across a wide 512-bit memory interface. This combination delivers exceptional memory bandwidth suited to high-resolution workloads, content creation, and demanding gaming scenarios at up to 7680×4320 (8K) resolution. Cooling is handled by an extra-thick 360×38mm radiator paired with three high-end fans to maximise heat dissipation. A full-coverage copper cold plate spans all heat-generating components on the PCB, channelling thermal load to the radiator with reported up to 30% better performance versus pure air cooling according to ASUS. A premium phase-change GPU thermal pad fills microscopic gaps between the GPU die and thermal module for superior conductivity. Secondary onboard cooling — an axial-tech fan and a low-profile heatsink under the shroud — handles power-delivery component heat quietly and efficiently. Power delivery is reinforced by 80-amp MOSFETs, which ASUS states provide over 35% more headroom versus standard designs, supporting stable operation and higher overclocking potential. The single 16-pin power connector is rated for high-wattage operation; ASUS recommends a minimum 1000W PSU. For display connectivity, the card offers two native HDMI 2.1b outputs and three native DisplayPort 2.1b outputs, supporting up to four simultaneous displays with HDCP 2.3 compliance. It occupies a 2.5-slot profile and includes ARGB Aura Sync lighting. Build quality is reinforced through ASUS Auto-Extreme automated single-pass soldering, a protective conformal PCB coating against moisture and dust, ASUS GPU Guard corner adhesive, and a GPU bracket for uniform mounting pressure.
