MSI Raider 18 HX AI A2XWJG-841US 18" UHD+ 120Hz Mini LED Ultra 9-285HX RTX 5090 128GB DDR5

Mobile workstation identity

The MSI Raider 18 HX AI A2XWJG-841US is an 18 inch mobile workstation built around an Intel Core Ultra 9 285HX processor with 24 cores and a 5.5 GHz maximum turbo frequency. It pairs that CPU with an NVIDIA GeForce RTX 5090 Laptop GPU carrying 24 GB of GDDR7 memory. The configuration targets professionals and enthusiasts who need desktop-class compute and graphics in a single chassis.

Display and storage interface limits

The 18 inch panel delivers a 3840 by 2400 UHD+ resolution at a 120 Hz refresh rate using Mini LED backlighting. Storage is provided by two 4 TB M.2 PCIe 4.0 x4 NVMe SSDs for an 8 TB total, so sequential throughput is bounded by the Gen4 lane speed. System memory consists of two 64 GB DDR5 5600 modules running in dual channel, limiting memory bandwidth to that data rate.

Thermal build and daily connectivity

HIDevolution applies Gelid GC Extreme thermal interface material to the CPU and GPU during assembly, aiming to reduce core temperatures under sustained load. The chassis measures 15.91 by 12.09 by 1.26 inches and weighs 7.94 pounds, a footprint that demands a spacious bag or desk area. Standard LAN and WLAN interfaces handle wired and wireless networking without additional adapters.
