MSI Raider 18 HX AI A2XWJG 18" UHD+ 120Hz Mini LED Ultra 9-285HX RTX 5090 64GB DDR5 1TB NVMe

18-inch UHD+ Mini LED gaming laptop

The MSI Raider 18 HX AI A2XWJG pairs an 18-inch UHD+ Mini LED panel running at 120 Hz with an Intel Core Ultra 9 285HX processor and an NVIDIA RTX 5090 laptop GPU equipped with 24 GB of GDDR7 memory. The system ships with 64 GB of DDR5 memory in a dual-channel configuration and a 1 TB PCIe 4.0 NVMe SSD, targeting enthusiasts who need desktop-class performance in a portable chassis. Windows 11 Pro is pre-installed and the unit is finished in Core Black.

Verify power, memory and storage compatibility

The CPU is a 24-core design with a maximum turbo frequency of 5.5 GHz and 36 MB of L3 cache, so confirm that your cooling expectations match a high-wattage mobile processor. Memory operates at 5600 MHz across two 32 GB modules, leaving no free slots for future expansion unless you replace the existing kit. The single 1 TB NVMe drive occupies one M.2 slot; additional storage requires an open M.2 connector on the motherboard.

Gelid GC Extreme TIM and 7.94 lb chassis

HIDevolution applies Gelid GC Extreme thermal interface material to both CPU and GPU during assembly, aiming to reduce peak temperatures and limit throttling under sustained load. The laptop measures 15.91 by 12.09 by 1.26 inches and weighs 7.94 pounds, so plan for a sturdy backpack and adequate desk space. A full quality-control pass including BIOS updates, burn-in testing and port verification is performed before shipment.
