The ASUS ROG Astral LC GeForce RTX 5090 OC Edition is a flagship liquid-cooled graphics card built on NVIDIA's Blackwell architecture, aimed at enthusiasts and creators who want top-tier RTX 5090 performance with lower thermals and noise than an air-cooled card. It pairs the full GB202 GPU (21,760 CUDA cores) with 32GB of GDDR7 memory on a 512-bit bus (28 Gbps), cooled by a factory-fitted 360mm AIO with a vapor-chamber block and ARGB lighting. Outputs are 3x DisplayPort 2.1b and 2x HDMI 2.1b, supporting up to 8K (7680x4320). Requires a 1000W PSU with a single 16-pin GC-HPWR connector; the 2.5-slot GPU block plus a 400mm radiator need careful case/radiator-mount planning before purchase.
