MSI Titan 18 HX AI A2XWJG · Core Ultra 9 285HX · RTX 5090 Laptop

Intel Core Ultra 9 285HX · NVIDIA GeForce RTX 5090 Laptop (175W) · 64GB DDR5-6400 · 6TB SSD (RAID 0) · 18″ 4K 120Hz Mini-LED · 3.6 kg
Premium Mg-Al alloy builddual Thunderbolt 5, four NVMe slots, great mechanical keyboard, vibrant 4K 120Hz mini-LED, 260W combined power. No G-Sync/Adaptive Sync, no Advanced Optimus, high noise & heat, high standby power draw, underwhelming haptic touchpad, slow SD reader. RTX 5090 barely outpaces RTX 4090 – huge premium with compromises.
