MSI Crosshair 18 HX AI Intel Core Ultra 9 275HX RTX 5070 64GB 2TB 18" QHD+ 240Hz Gray gaming

18-inch QHD+ 240 Hz gaming laptop

The MSI Crosshair 18 HX AI pairs an 18.0-inch IPS panel at 2560 x 1600 resolution with a 240 Hz refresh rate and 100% DCI-P3 coverage. An Intel Core Ultra 9 275HX processor with 24 cores and 64GB of DDR5 5600 memory drives the system. A GeForce RTX 5070 GPU with 8GB GDDR7 video memory handles graphics. A 2TB PCIe Gen 4x4 NVMe SSD stores the operating system and games. Windows 11 Home ships pre-installed.

Sustained load behaviour

The 240 W power adapter feeds the 24-core processor and RTX 5070 while the four-cell 90 Whr battery remains available for mobile use. Thermal design targets stable clocks during extended sessions rather than short burst frequencies. The 10/100/1000 Mbps LAN port and Intel Wi-Fi 6E AX211 with Bluetooth 5.3 maintain network connectivity under load. Rear-mounted HDMI v2.1, USB-A 3.2 Gen1 and RJ45 ports keep cable routing tidy during long gaming periods.

Deciding specification

The GeForce RTX 5070 with 8GB GDDR7 determines whether this laptop meets a buyer's performance target for modern titles at QHD+ resolution. Buyers needing more video memory or a higher GPU tier should consider other configurations. The 64GB DDR5 5600 capacity and 2TB NVMe SSD are fixed and not user-expandable beyond the installed specifications.
