18-inch QHD+ 240Hz gaming laptop

The MSI Crosshair 18 pairs an 18.0-inch QHD+ panel at 2560 x 1600 with a 240Hz refresh rate. An Intel Core Ultra 9 275HX processor delivers 24 cores and a 5.4 GHz turbo frequency. The NVIDIA GeForce RTX 5070 laptop GPU provides 8GB of GDDR7 video memory. The system includes 32GB of DDR5 memory and a 1TB PCIe SSD. Windows 11 Pro comes pre-installed.

Sustained load behaviour

The 24-core processor combines 8 performance cores with 16 efficient cores to maintain throughput during extended sessions. Thunderbolt 5 ports support high-bandwidth peripherals without throttling the internal PCIe bus. The 18-inch chassis provides thermal mass for the CPU and GPU under continuous load. Wi-Fi 6E and Bluetooth handle wireless connectivity while the RJ-45 jack offers a wired alternative.

Upgrade context

This configuration replaces earlier 16-core mobile workstations that lacked Thunderbolt 5 and GDDR7 graphics memory. The jump is worthwhile when workloads need 24 threads, 240Hz panel response, and the 36MB cache of the Ultra 9 275HX. Buyers moving from 15-inch QHD machines gain the larger 18.0-inch display area and the 1TB PCIe SSD capacity in a single step.

Questions about this item

How loud and hot does the 24-core Ultra 9 275HX get during all-day loads?

The 24-core Ultra 9 275HX runs up to 5.4 GHz inside an 18-inch chassis weighing 6.83 pounds with 1.17-inch thickness, giving the cooling system substantial room to manage sustained heat and fan noise.

Which cables or peripherals must I already own to use the Thunderbolt 5 and HDMI 2.1 ports?

You need Thunderbolt 5-certified cables for the two Thunderbolt 5 ports and an HDMI 2.1 cable for the HDMI 2.1 output; the three USB 3.2 Gen 2 Type-A ports accept standard USB-A plugs.

Will my older USB 3.2 Gen 1 drives and displays work with the three USB 3.2 Gen 2 Type-A ports and HDMI 2.1?

Yes — the three USB 3.2 Gen 2 Type-A ports are backward compatible with USB 3.2 Gen 1 devices, and the HDMI 2.1 port works with older HDMI displays at their native capabilities.
