18-inch QHD+ 240Hz gaming laptop

The MSI Crosshair 18 HX AI is an 18-inch gaming laptop built around a 2560 x 1600 QHD+ display running at 240Hz. It pairs an Intel Core Ultra 9 275HX 24-core processor with an NVIDIA GeForce RTX 5070 GPU carrying 8GB of GDDR7 video memory. The system ships with 64GB of DDR5 memory and a 2TB PCIe SSD, running Windows 11 Pro.

Upgrading from lower-tier mobile GPUs

Moving to this configuration makes sense when the previous machine topped out at a 1080p panel or a GPU with less video memory. The 240Hz refresh rate and QHD+ resolution together demand more graphics throughput than entry-level mobile cards can sustain in modern titles. If the current laptop already runs a comparable RTX mobile GPU at 1440p, the visual jump will be marginal.

Suits users who need high refresh 1440p on a large

This laptop suits buyers who want an 18-inch form factor with a fast 240Hz QHD+ screen, 64GB of memory and Thunderbolt 5 connectivity for external peripherals. It is less suited for anyone prioritising portability, because the chassis measures 15.9 x 11.02 x 1.17 inches and weighs 6.83 pounds. Buyers needing an SD card reader or a fingerprint sensor should look elsewhere.

Questions about this item

What are the exact chassis dimensions of the 18.0-inch Crosshair 18 so I can check bag fit?

The laptop measures 15.9 x 11.02 x 1.17 inches and weighs 6.83 pounds, so verify your sleeve or backpack compartment against those figures.

Which screw type and drive count secure the bottom cover for the DDR5 and PCIe SSD upgrades?

Remove every visible Phillips-head screw on the underside; the step most people miss is the two screws hidden beneath the rear rubber feet.

When will the 2 TB PCIe SSD likely need replacement under heavy write workloads?

Consumer TLC drives of this capacity typically reach their rated TBW after several years of sustained heavy writes; monitor SMART health in Windows 11 Pro and replace when the wear indicator approaches the limit.
