18-inch QHD+ 240Hz display

The 18.0 inch panel runs at 2560 x 1600 resolution with a 240Hz refresh rate. An IPS matrix provides wide viewing angles and consistent colour across the screen. The non-touch surface avoids glossy reflections during long sessions. This size and speed suit competitive gaming and content review alike.

Intel Core Ultra 9 275HX sustained performance

The 24-core processor combines 8 performance and 16 efficient cores with 36 MB smart cache. Under continuous load the chip manages thermals while holding high frequencies up to 5.4 GHz turbo. The 24 threads keep background tasks from stalling the foreground workload. This balance helps maintain frame rates during extended play.

Thunderbolt 4 and HDMI 2.1 connectivity

One USB-C port carries Thunderbolt 4 with DisplayPort and Power Delivery 3.0 support. A single HDMI 2.1 output drives external displays at high refresh rates. Three USB-A 3.2 Gen1 ports and an RJ45 jack complete the wired interface. Bandwidth limits follow the Thunderbolt 4 and HDMI 2.1 specifications.

Questions about this item

How loud and hot does the 24-core Ultra 9 275HX get when the laptop runs all day?

The 24-core Ultra 9 275HX reaches 5.4 GHz turbo and shares the 18-inch chassis with the RTX 5070 8GB GDDR7, so sustained loads will spin the fans and warm the keyboard deck; MSI's Cooler Boost design helps move heat out the rear vents.

What must I already own to use the Thunderbolt 4 port with Power Delivery 3.0?

You need a Thunderbolt 4 or USB-C device that accepts PD 3.0 charging and DisplayPort alt-mode — for example a compatible dock, monitor or eGPU — and a matching cable rated for 40 Gbps.

Will my older USB-A 3.0 peripherals work with the three USB-A 3.2 Gen1 ports?

Yes, the three USB-A 3.2 Gen1 ports are backward compatible with USB 3.0 and USB 2.0 devices, so existing mice, keyboards and drives will connect at their native speeds.
