18-inch QHD+ 240Hz gaming laptop

The MSI Crosshair 18 HX AI pairs an 18.0" IPS panel at 2560 x 1600 with a 240 Hz refresh rate and 100% DCI-P3 coverage. An Intel Core Ultra 9 275HX with 24 cores drives the system alongside 32GB of DDR5 5600 memory and a 2TB PCIe NVMe SSD. Graphics come from an NVIDIA GeForce RTX 5070 laptop GPU with 8GB of GDDR7 video memory. Windows 11 Home is pre-installed.

Who this suits and who should look elsewhere

This machine targets gamers and creators who need a large, high-refresh display and strong multi-threaded CPU performance in a single chassis. The 24-core processor and 32GB of RAM handle heavy workloads and modern titles at QHD+ resolution. Buyers who prioritize portability, longer battery life away from a wall outlet, or a smaller footprint should consider more compact alternatives.

Deciding specification — 240 Hz QHD+ panel

The 18.0" QHD+ display running at 240 Hz is the single spec that determines fit. It delivers the resolution and motion clarity required for competitive gaming and detailed content work. If the target use case does not demand that combination of size, pixel density and refresh rate, a different panel configuration will serve better.

Questions about this item

What are the laptop dimensions and weight so I can check bag fit?

The chassis measures 15.9 by 11.02 by 1.17 inches and weighs 6.83 lbs, so verify your sleeve or backpack fits an 18-inch form factor.

Does the 240 W power brick use a proprietary barrel plug or USB-C PD, and which port handles charging?

The included 240 W adapter connects via the dedicated barrel jack; the single USB-C Thunderbolt 4 port supports DisplayPort and PD 3.0 but not full system charging.

How do I replace the 90 Whr battery when it wears out?

The 4-cell 90 Whr pack is internal; swap it by removing the bottom cover screws, disconnecting the battery cable, and fitting the new unit.
