| The ROG Strix Scar 18 2026 will ship with a 4K Mini LED display. |
ASUS is preparing to unleash what could be its most powerful gaming laptop to date, with a leaked ROG Strix Scar 18 (2026) prototype hinting at unprecedented power delivery and a stunning 4K display upgrade.
Earlier this week, ASUS officially kicked off its 2026 gaming laptop season with the announcement of a trio of new ROG Strix models. While the company shared extensive details about the upcoming ROG Strix G16 2026 and ROG Strix G18 2026, they also confirmed that an updated version of the flagship ROG Strix Scar 18 is on the horizon—and if a new leak is any indication, this machine is shaping up to be a true desktop replacement in every sense of the word.

A Hefty Power Leap: The 450W Adapter
Currently, ASUS has only teased that it will reveal more details about the ROG Strix Scar 18 (2026) "in the coming months," with a suggested official launch window sometime between April and June. However, while the company plays its cards close to the chest, leakers are filling in the gaps.
According to information shared by X account Huang514613, the new 18-inch behemoth will ship with a massive new AC adapter capable of delivering up to 450 watts. For context, last year’s model utilized a 330W or 380W adapter depending on the configuration. While the new charger retains the familiar rectangular connector, the leaker notes that this power increase is designed to allow the new Strix Scar 18 to "fully stretch its legs"—a clear indication that ASUS is aiming to push the limits of the internal hardware without power throttling.
The leaked comparison image also reveals a notable physical change: the 2026 model weighs approximately 430 grams more than its predecessor. This weight gain strongly suggests that ASUS has installed a significantly beefier cooling solution to manage the thermal demands of the new components. Considering we encountered no major thermal issues when reviewing last year's model, this extra heft points to an aggressive performance target that likely requires a completely redesigned vapor chamber or liquid metal implementation.
For those looking to compare the previous generation, you can still check out the current ROG Strix Scar 18 model available on Amazon , though the 2026 version is shaping up to be a substantial upgrade.
4K Mini LED Meets a 240Hz Refresh Rate
Perhaps the most significant visual upgrade comes in the display department. ASUS is reportedly equipping the new ROG Strix Scar 18 with a 4K Mini LED panel. Outputting at a crisp 3,840 x 2,400 pixels in a 16:10 aspect ratio, this new screen marks a massive resolution jump from last year’s 2,560 x 1,600 display.
Gamers worried about a trade-off between resolution and smoothness can breathe easy—the new panel maintains the silky 240 Hz refresh rate that high-end gamers expect, along with full 100% DCI-P3 color space coverage. The inclusion of Mini LED technology suggests that users can also expect superior contrast ratios and HDR performance, making this laptop equally suited for AAA gaming marathons and professional creative work.
Next-Gen Silicon: Intel Core Ultra 9 290HX Plus and RTX 5090
Under the hood, the ROG Strix Scar 18 (2026) is poised to be a launch vehicle for some of the most anticipated hardware of the year. According to the leak, the laptop will pair Intel’s Core Ultra 9 290HX Plus processor with Nvidia’s GeForce RTX 5090 laptop GPU.
The "Plus" variant of Intel’s flagship HX chip is expected to offer higher sustained clock speeds compared to the standard Ultra 9 290HX, while the RTX 5090 will represent Nvidia’s next-generation Blackwell architecture for laptops. Combined with the 450W power delivery system, this configuration is positioned to compete directly with high-end desktop gaming rigs.
While ASUS has remained silent on pricing for the 2026 flagship, the combination of a 4K Mini LED screen, next-gen silicon, and a 450W power envelope suggests that the new Strix Scar 18 will command a premium price point. The current model retails for around $3,599 on Amazon, and given the substantial upgrades, a price increase for the 2026 iteration seems likely.
