Built for heavy compute and play

The MSI Raider 18 HX AI A2XWJG pairs an Intel Core Ultra 9 285HX with an NVIDIA GeForce RTX 5090 Laptop GPU carrying 24 GB of GDDR7 video memory. The 24-core processor reaches a 5.5 GHz max turbo frequency and includes 36 MB of L3 cache. A 32 GB DDR5 5600 MHz dual-channel kit and 8 TB of PCIe 4.0 NVMe storage complete the platform. Windows 11 Home is pre-installed.

Sustained workload behaviour

Gelid GC Extreme thermal interface material is applied to the CPU and GPU during the build-to-order process. The upgrade targets lower core temperatures during extended heavy loads to reduce the likelihood of thermal throttling. A full burn-in stress test validates temperature stability before the system ships. The 120 Hz Mini LED panel runs at 3840 x 2400 resolution.

Thermals noise and power

The custom TIM application aims to keep the 24-core processor and RTX 5090 cooler under normal gaming and content-creation sessions. Lower sustained temperatures help the fans spin at reduced speeds, which cuts acoustic output. The 18-inch chassis measures 15.91 x 12.09 x 1.26 inches and weighs 7.94 lbs, providing internal volume for the cooling solution.

Questions about this item

Will the 18-inch UHD+ Mini LED panel fit on my desk and in a standard laptop bag?

The chassis measures 15.91 by 12.09 by 1.26 inches and weighs 7.94 lbs, so verify your bag’s internal dimensions and desk depth before buying.

Can the 32 GB of DDR5 memory be upgraded later if I need more capacity?

The system ships with 32 GB in a 2 x 16 GB dual-channel configuration; check the service manual for the maximum supported capacity and available slots.

Does the 8 TB storage arrive as a single drive or multiple modules, and is it user-replaceable?

It is configured as 2 x 4 TB M.2 PCIe 4.0 NVMe SSDs, so both modules are accessible for future replacement or expansion.
