Victory, accelerated.

Game with the greatest, backed up by the power of up to Intel® Core™ Ultra 9 processor 275HX. With 8 Performance and 16 Efficient cores, this next-gen silicon can drive high framerates in esports and AAA games alike. The SCAR 18 also has access to AI acceleration in select content creation apps, giving you incredible flexibility on how you can utilize your gaming machine.

The best of the best

The 2025 Strix SCAR 18 offers the very best Windows 11 Pro gaming experience, featuring up to Intel® Core™ Ultra 9 processor 275HX and up to NVIDIA® GeForce RTX™ 5090 Laptop GPU with NVIDIA Max-Q technologies, including Advanced Optimus. This killer hardware is complemented with up to 64GB of 5600MHz DDR5 RAM and 4TB of PCIe 4.0 storage, with the memory slots upgradable to 6400MHz DDR5 RAM and SSD slots both offering full support for PCIe Gen 5, ensuring that you always have the edge on your competition.

Ultimate power

Performance requires power, so we’ve cranked the SCAR 18 to the max. In Turbo mode, the max wattage is 55W for the CPU and an incredibly high 175W for the GPU. For those willing to tinker in Manual mode, you have access to an additional 25W for the CPU, for a total system max wattage of 255W. No matter what kind of gamer you are, the raw power on tap with the Strix SCAR 18 will give you a leg up on your opponents.

Your Ultimate Pit Stop

We’ve completely redesigned the 2025 Strix SCAR 18 to make upgrades easier than ever. This tool-less design allows for simple access to both the RAM, SSD, and fans, and we’ve also brought our latest Q-latch system here for those SSD slots. Like an experienced pit crew, you can remove and replace your SSD and RAM in seconds, having the machine back up and running without missing a lap. A specially designed frame covers the rest of the mainboard to protect the other components, but can easily be removed with a few screws for users who want to tinker further.

ROG Intelligent Cooling

We’ve completely revamped the cooling solution of the 2025 Strix SCAR 18 with precise calculations in mind to ensure that you get the best gaming experience with your machine, every time. We relocated all of the exhaust vents to the rear of the hinge, keeping warm air away from your mousing hand. The sides and bottom of the machine act as an air intake, creating a natural, efficient path for airflow. Air also flows through the keyboard deck, keeping your hands cooler during intense gaming sessions. When pairing an end-to-end vapor chamber with a sandwiched heatsink, Tri-Fan Technology, and Conductonaut Extreme liquid metal on both CPU & GPU, the 2025 Strix SCAR 18 achieves a lower noise level in Turbo Mode compared to the previous generation, while still offering the same calculated excellence you expect from a Strix SCAR machine.

ROG Nebula HDR

Your laptop’s display is a window into new worlds, which is why we put the absolute best on our ROG Strix SCAR 18. This ROG Nebula HDR display with Mini LED technology features over 2000 dimming zones, 1200 nits of peak brightness, and beautiful colors thanks to 100% coverage of the DCI-P3 color space. The 2025 SCAR 18 has also been upgraded with a brand-new dual ACR layer, which reduces reflections and enhances contrast by 4.5X for incredibly vivid colors. When combined with our own Nebula HDR engine, this display ensures every game and movie is done true justice. And with a blazing fast refresh rate of 240Hz and full NVIDIA G-SYNC support, motion will be incredibly smooth, allowing you to see every enemy before they see you.

Studio-quality Sound

Dolby Atmos-powered speakers include two tweeters and two downward firing woofers to create an authentic sound stage for your games. Hi-Res audio ensures you hear your music in the same quality it was recorded. Two-Way AI Noise Cancelation processes both incoming and outgoing audio to filter any errant background noises, making sure that your calls, chats and streams come through without distraction.
