18-inch UHD+ Mini LED gaming laptop

This 18-inch MSI Raider 18 HX AI A2XWJG-841US laptop pairs an Intel Core Ultra 9 285HX 24-core processor with an NVIDIA GeForce RTX 5090 laptop GPU carrying 24 GB GDDR7 video memory. The 120 Hz Mini LED panel runs at 3840 x 2400 resolution. Windows 11 Home comes pre-installed for immediate use.

Check power and thermal headroom before ordering

The 24-core CPU reaches a 5.5 GHz max turbo frequency and the discrete GPU carries 24 GB GDDR7, so sustained loads will draw significant power from the AC adapter. Verify your workspace has stable mains supply and adequate ventilation for a 7.94 lb chassis measuring 15.91 x 12.09 x 1.26 inches. The 32 GB DDR5 5600 MHz dual-channel memory and 4 TB PCIe 4.0 NVMe storage are already configured.

Thermals, noise and power draw in normal use

HIDevolution applies Gelid GC Extreme thermal interface material on both CPU and GPU to lower peak temperatures and reduce throttling during intensive workloads. A full burn-in stress test validates thermal behaviour before shipment. Expect fan noise to rise under combined CPU and GPU load while the cooling system manages the 36 MB L3 cache processor and high-wattage graphics silicon.

Questions about this item

What comes in the box and what must be bought separately?

The laptop ships with the 18" UHD+ Mini LED display, Intel Core Ultra 9-285HX, NVIDIA GeForce RTX 5090 24 GB GDDR7, 32 GB DDR5 5600 MHz, 4 TB PCIe 4.0 NVMe SSD, Windows 11 Home, Gelid GC Extreme on CPU and GPU, and the power adapter. No extra parts are required for operation.

Which configuration should I choose among the listed versions?

This model is offered as a single configuration: 24-core Ultra 9-285HX at 2.1 GHz up to 5.5 GHz, 32 GB DDR5, 4 TB SSD (2 x 2 TB), 18" 3840 x 2400 120 Hz Mini LED, RTX 5090 24 GB GDDR7, Core Black chassis, 7.94 lbs.

What does the 5.5 GHz max turbo frequency mean in daily use?

The 24-core processor can boost up to 5.5 GHz on demanding threads, so heavy compiles, 3D renders, and high-refresh gaming see peak single-thread speed while the Gelid GC Extreme paste helps sustain clocks under load.
