Core Hardware

This MSI Crosshair 18 HX AI is an 18 inch gaming laptop built around an Intel Core Ultra 9 275HX processor with 24 cores and 24 threads. It targets users who need desktop-class multi-threaded performance in a portable chassis. The system ships with 64GB of DDR5 5600 memory and a 2TB PCIe Gen 4x4 NVMe SSD. Windows 11 Pro is pre-installed.

Display and Graphics Headroom

The 18.0 inch IPS panel delivers a 2560 x 1600 QHD+ resolution at 240 Hz with 100% DCI-P3 coverage. An NVIDIA GeForce RTX 5070 laptop GPU with 8GB GDDR7 drives the screen for high-refresh competitive play and content creation. The 240W adapter and 90Whr battery set the practical ceiling for sustained combined CPU and GPU load.

Deciding Specification

The 24-core Intel Core Ultra 9 275HX running up to 5.4 GHz is the single figure that determines fit. If your workload scales across all 24 threads at high frequency this machine matches it; if you only need strong single-thread speed a lower-tier CPU will suffice.

Questions about this item

Will the HDMI 2.1 port drive my older 1080p monitor at its native resolution?

Yes, the HDMI 2.1 output supports 1080p and higher resolutions, so your existing monitor will work at its native setting.

How can I verify the 240 Hz panel is actually running at 240 Hz after I set up Windows 11 Pro?

Open Settings > System > Display > Advanced display and confirm the refresh rate dropdown shows 240 Hz for the internal 18" QHD+ panel.

Does the box include a Thunderbolt 4 cable or do I need to buy one separately for my external SSD?

The 240 W power adapter is included; a Thunderbolt 4 cable for peripherals is not supplied and must be purchased separately.
