18-inch UHD+ 240Hz Mini LED gaming laptop

The MSI Titan 18 HX A2WJ-1258US pairs an 18-inch UHD+ 240Hz Mini LED panel with an Intel Core Ultra 9 290HX Plus 24-core processor and NVIDIA GeForce RTX 5090 Laptop GPU with 24 GB GDDR7. It ships with 128 GB DDR5 5600 MHz memory and 32 TB PCIe 4.0 NVMe storage across two 8 TB drives. Windows 11 Pro is pre-installed.

Gelid GC Extreme thermal compound on CPU and GPU

HIDevolution applies Gelid GC Extreme thermal interface material to both the CPU and GPU to lower system temperatures and reduce throttling during sustained workloads. A full burn-in stress test verifies thermal behaviour before shipment. The chassis measures 15.91" x 12.11" x 0.94-1.26" and weighs 7.94 lbs.

HIDevolution quality-control and upgrade validation

Each unit receives a complete quality check including latest BIOS and driver installation, benchmark validation, keyboard and touchpad test, port functionality check, display inspection and physical chassis review. Upgrades are covered under warranty and the build is performed by an authorized MSI BTO dealer.

Questions about this item

How do I install the Gelid GC Extreme thermal interface material on the Ultra 9-290HX Plus CPU and RTX 5090 GPU?

The Gelid GC Extreme TIM is pre-applied by HIDevolution during the build process; no user installation is required. The step buyers often miss is verifying that the latest stable BIOS firmware is installed before heavy workloads, which the vendor performs during quality control.

What maintenance or replacement will the 128 GB DDR5 5600MHz memory and 32 TB PCIe 4.0 NVMe SSD need later?

The DDR5 memory and PCIe 4.0 NVMe SSDs are solid-state components with no moving parts, so they require no scheduled maintenance. If capacity or speed needs change, both the two 64 GB memory modules and the two 8 TB M.2 drives are user-replaceable.

Which limit appears first under sustained load on the 18-inch UHD+ 240Hz Mini LED display with the RTX 5090 24 GB GDDR7 GPU?

Sustained gaming at 3840 x 2400 resolution and 240 Hz will hit the GPU thermal envelope first. The Gelid GC Extreme compound and the 0.94-1.26 inch vapour-chamber cooling keep temperatures lower, but the 24 GB GDDR7 frame buffer and 5.5 GHz CPU turbo ceiling define the performance ceiling.
