Verdict

The ASUS ROG Astral LC GeForce RTX 5090 is a flagship liquid-cooled graphics card featuring the NVIDIA Blackwell architecture with 21,760 CUDA cores and 32GB of GDDR7 memory on a 512-bit bus. Key characteristics include an integrated 360mm AIO radiator with magnetic daisy-chainable fans, a full-coverage cold plate, and a high-end 24-phase power delivery system utilizing 80-amp MOSFETs. Main pros consist of unrivaled 4K gaming and AI performance, exceptionally low operating temperatures (often staying in the low 60°C range), and a factory-overclocked boost clock of 2610 MHz in OC mode. However, notable cons include its extreme price tag, the significant physical footprint of the 360mm radiator, and high power consumption that can peak at a 600W limit.
