ASUS announced the 2026 model of ROG Strix SCAR 18 with its new processor, high-end display, renewed cooling system and total system power increased to 320W. The new model includes an Intel Core Ultra 9 Processor 290HX Plus processor and NVIDIA GeForce RTX 5090 Laptop GPU with a maximum TGP value of 175W. ROG Strix SCAR 18 2026 increases its power on the processor side. ASUS ROG Strix SCAR 18 2026 is positioned as the company’s 18-inch flagship gaming laptop.
The remarkable thing about the new model is not only that it uses the RTX 5090 Laptop GPU; Increasing the total power budget of the system to 320W. In Turbo mode, the processor operates with 95W power and the GPU operates with 175W power. In manual mode, an additional 50W power field is opened to the processor and the total system power reaches 320W. While the maximum TGP on the GPU side is again kept at 175W, the real increase is seen in the power budget on the processor side.
The new SCAR 18 uses the Intel Core Ultra 9 Processor 290HX Plus processor. This processor offers a total of 24 cores and 24 threads, with 8 performance cores and 16 efficiency cores. The processor, whose maximum turbo frequency is announced as 5.5 GHz, is listed on ASUS’s product page with a sustainable power value of up to 200W. This structure makes room for high frame rates during gaming and additional workloads such as simultaneous broadcasting, voice chat or content production.
Meet the next evolution of gaming performance with the ROG Strix SCAR 18, engineered to push power, visuals, and immersion to the next level. 320W Dominance. 4K Flagship. 🔥 Pre-orders are now available. pic.twitter.com/xMMkzQTf94— ROG Global (@ASUS_ROG) May 15, 2026 On the graphics side, there is NVIDIA GeForce RTX 5090 Laptop GPU. This GPU comes with 175W maximum TGP, Dynamic Boost, Advanced Optimus, DLSS 4.5, Multi Frame Generation and 24 GB GDDR7 memory.
According to the information provided by ASUS, there is also 1824 AI TOPS value on the GPU side. This hardware is not only about gaming performance; It also focuses on 3D workflows, video editing and production processes working with large files. The model supports up to 128 GB DDR5-6400 memory and up to 8 TB PCIe Gen5 SSD storage. On the memory side, 64 64 GB configurations are supported. On the storage side, there are two upgradeable M.2 2280 slots, and both SSD slots offer PCIe Gen5 support.
ASUS uses the Q-Latch system in its SSD slots; Thanks to this structure, M.2 SSDs can be installed and removed without using screws. The screen of ROG Strix SCAR 18 2026 is one of the main points that distinguishes it from the previous models of the series. The device has an 18-inch Mini LED ROG Nebula HDR panel with 4K resolution and 240Hz refresh rate. The panel comes with 3 ms response time, 1600 nits peak brightness, over 2000 dimming zones, 100 percent DCI-P3 color coverage, DisplayHDR 1000, Dolby Vision, Pantone verification, NVIDIA G-SYNC and Adaptive Sync support.
ASUS also uses ROG Nebula ELMB technology in this model. While in traditional ELMB solutions, the backlight is activated simultaneously on the entire panel, ROG Nebula ELMB works in 40 separate zones using the Mini LED structure. This system matches pixel transitions to backlight timing more precisely. ASUS states that this technology provides up to 16 times motion clarity. The panel also features AGLR technology for reflection reduction and low reflection.
This coating reduces reflections by 55 percent and increases contrast by up to 4.5 times. The cooling system has also been renewed for high power values. The 2026 ROG Strix SCAR 18 uses an end-to-end vapor chamber, sandwich-shaped cooler block, Tri-Fan Technology, and Conductonaut Extreme liquid metal on the CPU and GPU. Since the hot air outlets are moved to the rear hinge section, the sides and bottom of the device work as air inlets.
This structure reduces hot air flow, especially on the mouse side. The new fan system comes with up to 84 LCP fan blades and, according to ASUS’s data, increases the total airflow by 91 percent compared to the previous generation SCAR 18. The full-width cooler section uses 0.1 mm ultra-thin copper fins and the cooler surface area is 246,898 mm². The system is designed to carry 320W total system power in Manual Mode. In lower power scenarios, the device can turn off the fans completely and switch to passive cooling.
On the connection side, there are dual Thunderbolt 5 ports, HDMI 2.1, three USB 3.2 Gen 2 Type-A connections, 2.5G Ethernet, 3.5 mm combined audio jack and DC power input. On the wireless side, there is Wi-Fi 7 and Bluetooth support. The device also has an FHD IR camera with Windows Hello support, a 90Wh battery and charging support via USB Type-C up to 100W. On the design side, the ROG line is maintained. There is an AniMe Vision LED area on the cover of the device.
According to ASUS’s statement, there are 810 LEDs and 8,522 precisely machined holes in this area. In this area, users can show ready-made animations, GIF files or images they have created. There is a full perimeter Aura RGB light strip at the bottom of the device. Stealth Mode in the Armory Crate offers a simpler look by turning off the lights. The dimensions of ROG Strix SCAR 18 2026 vary between 39.9 x 29.8 x 2.35 and 3.5 cm.
The weight is announced as 3.7 kg. These values show that the device is positioned in the high-performance laptop class, which is a desktop alternative rather than portable.
