MSI Titan 18 HX AI (A2XW)
Flagship desktop-replacement
A no-compromise 18" flagship — RTX 5090 at the full 175 W, a 4K Mini LED panel, and up to 128 GB RAM. The trade-off is heat and noise: owners report 96–100 °C CPU temps and prominent fan noise at full draw, and there is no G-Sync. A desk-bound powerhouse, not a quiet one.
