18" QHD+ 240Hz Gaming Laptop

The MSI Crosshair 18 HX AI 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. It ships with 32GB DDR5 RAM and a 2TB PCIe SSD running Windows 11 Home. The 2560 x 1600 display offers a 240Hz refresh rate for smooth motion in fast-paced titles.

Who This Suits and Who Should Look Elsewhere

This machine suits users who need a large, high-refresh screen and strong multi-core CPU performance for gaming and content creation. The 24-core design handles heavy multitasking and compute workloads. Buyers who prioritise maximum GPU memory for 4K textures or professional rendering should look at configurations with higher video memory capacity.

8GB GDDR7 Video Memory Decides Fit

The single specification that determines suitability is the 8GB GDDR7 frame buffer on the RTX 5070. It delivers high bandwidth for 1440p gaming but limits texture capacity at higher resolutions. If your workflow demands more than 8GB of VRAM, this model will not meet that requirement.

Questions about this item

Do I need a separate power adapter to run the Ultra 9 275HX at its 5.4 GHz turbo?

The laptop ships with its own power supply; no extra adapter is required for the processor to reach 5.4 GHz.

Will my older USB 3.0 peripherals work with the 3.2 Gen 2 Type-A ports on this machine?

Yes, the three USB 3.2 Gen 2 Type-A ports are backward compatible with USB 3.0 and 2.0 devices.

How can I confirm the 240 Hz panel is actually running at 240 Hz after setup?

Open Windows Settings > System > Display > Advanced display and verify the refresh rate shows 240 Hz.
