18-inch QHD+ gaming laptop

The MSI Crosshair 18 HX AI Cosmo Gray is an 18-inch gaming laptop built around a 24-core Intel Core Ultra 9 275HX processor and an NVIDIA GeForce RTX 5070 GPU with 8GB GDDR7 memory.

Check power, display and port needs

Verify that your workspace can accommodate the 90Wh battery and the supplied power adapter for sustained loads. Ensure any external monitors you plan to use support HDMI 2.1 for full resolution and refresh rate passthrough. Confirm that your peripherals match the available Thunderbolt 4, three USB-A 3.2 ports and RJ45 Ethernet for wired networking.

Aluminium chassis with per-key RGB

The Cosmo Gray aluminium chassis measures 11.02 x 15.9 x 1.17 inches and weighs 6.84 pounds, giving a rigid feel without excessive bulk. A 24-zone RGB backlit keyboard provides per-key illumination for low-light sessions. Thunderbolt 4 enables high-speed docks and external GPUs, while the HD privacy camera includes a physical shutter for daily privacy.
