MSI Crosshair 18 HX AI gaming laptop 18" QHD+ 240Hz Ultra 9 275HX 32GB DDR5 4TB RTX 5070

18-inch QHD+ 240Hz gaming laptop

The MSI Crosshair 18 HX AI combines an 18-inch IPS panel at 2560 x 1600 with a 240Hz refresh rate and 100% DCI-P3 coverage. An Intel Core Ultra 9 275HX processor with 24 cores and 36MB smart cache drives the system alongside 32GB of DDR5 memory. A GeForce RTX 5070 laptop GPU with 8GB GDDR7 handles graphics workloads, while a 4TB SSD provides storage capacity. Windows 11 Home ships pre-installed.

90Wh battery and thermal management

The 90Wh battery powers the platform during mobile use. Cooler Boost 5 thermal design manages heat from the 24-core processor and dedicated GPU under sustained loads. Fan behaviour scales with component temperature to balance airflow against acoustic output. Power draw varies with workload intensity across the CPU and GPU combination.

Thunderbolt 4 and peripheral connectivity

A single Thunderbolt 4 port supports high-speed data, display output and charging through one connector. Three USB-A 3.2 ports, HDMI 2.1 and RJ45 Ethernet cover legacy and wired networking needs. The 24-zone RGB keyboard and HD privacy camera integrate into the Cosmo Gray chassis measuring 11.02 x 15.9 x 1.17 inches at 6.84 pounds. Wi-Fi 6E and Nahimic 3 audio complete the feature set.
