Overview
The MSI Raider 18 HX is unapologetically large. The 18” display, 64 GB of RAM, and RTX 5080 at full 150W TGP make it a desktop replacement that happens to fold shut. If you want the biggest screen and the most power in a laptop chassis, this is it.
Display
The 18” QHD+ (2560x1600) IPS panel at 240Hz is the Raider’s defining feature. The extra screen real estate compared to 16” laptops is immediately noticeable. Games feel more immersive, and multitasking with side-by-side windows is comfortable. Color accuracy is good (95% DCI-P3) with 350-nit brightness.
Performance
The RTX 5080 Laptop at 150W TGP is running at its maximum power limit, which puts it ahead of the same GPU in thinner laptops that power-limit to 100-120W. Paired with the Core Ultra 9 285HX and 64 GB of DDR5, there’s no bottleneck.
In games: expect 100+ fps at QHD+ in most AAA titles with max settings. Competitive shooters hit the 240Hz limit easily. The 240Hz panel matches the GPU output perfectly.
Thermals and Noise
MSI’s Cooler Boost 5 system with multiple fans and heat pipes keeps the CPU and GPU from throttling, but the trade-off is noise. Under full gaming load, fan noise hits 50+ dBA. You’ll want headphones.
Build
At 6.83 lbs plus the charger, the Raider 18 HX lives on a desk. The chassis is thick and sturdy. The per-key RGB keyboard has satisfying key travel, and the large trackpad works well. MSI’s build quality is good if not luxury, no creaks or flex.
Battery
The 99.9 Wh battery (FAA maximum) lasts 5-6 hours for productivity and under 2 hours of gaming. This is expected for the hardware inside. Keep the 330W charger handy.
