Victory, accelerated.

For gamers who refuse to compromise on performance, visuals or upgradeability, the new ROG Strix SCAR 18 G835 is built to deliver an uncompromising gaming experience in a laptop form factor.

The 2026 ROG Strix SCAR 18 combines an Intel Core Ultra 9 290HX Plus processor with up to an NVIDIA GeForce RTX 5090 Laptop GPU, a 4K 240Hz Mini LED display, advanced ROG cooling and support for up to 128GB of DDR5 memory and 8TB of PCIe storage.

But the SCAR 18 isn't simply about putting powerful components into a large chassis. It has been engineered around a single objective: giving gamers the performance and features they need to play, compete and create at the highest level.

Here's everything you need to know about the new ROG Strix SCAR 18 G835.

Flagship performance with Intel Core Ultra 9

At the heart of the ROG Strix SCAR 18 G835 is the Intel Core Ultra 9 290HX Plus processor.

The processor features 24 cores and 24 threads, with a maximum turbo frequency of up to 5.5GHz and an Intel AI Boost NPU capable of up to 13 TOPS.

For gamers, this provides the processing power needed for demanding modern games, while the additional CPU headroom can also benefit streaming, content creation, multitasking and other demanding workloads.

The SCAR 18 is therefore more than just a gaming machine. It can also serve as a powerful mobile workstation for users who need serious processing performance.

Up to NVIDIA GeForce RTX 5090 Laptop GPU

The headline feature for many gamers will be the graphics hardware.

The ROG Strix SCAR 18 G835 can be configured with an NVIDIA GeForce RTX 5090 Laptop GPU featuring 24GB of GDDR7 memory and a maximum TGP of 175W.

For gamers who want flagship graphics performance, this is the configuration to watch.

The 2026 SCAR 18 is also available in configurations featuring an NVIDIA GeForce RTX 5080 Laptop GPU with 16GB of GDDR7, depending on the SKU and market.

Why does GPU power matter?

Modern games increasingly rely on powerful GPUs for high-resolution textures, ray tracing, advanced lighting and AI-powered graphics technologies.

The NVIDIA GeForce RTX 50 Series also brings technologies such as DLSS 4.5 and Multi Frame Generation to supported games, allowing gamers to take advantage of AI-assisted performance and image quality improvements.

For anyone interested in understanding exactly what the SCAR 18 can deliver, the full G835 specifications provide a detailed breakdown of the available configurations.

A 4K 240Hz Mini LED display

Powerful hardware deserves a display capable of showing it off.

The ROG Strix SCAR 18 features an 18-inch ROG Nebula HDR display with a 4K resolution of 3840 × 2400 and a 16:10 aspect ratio.

The Mini LED panel features more than 2,000 dimming zones, a 240Hz refresh rate, 100% DCI-P3 colour coverage and a 3ms response time. It can also reach up to 1,600 nits of peak brightness.

This combination is particularly impressive because it brings together two qualities gamers don't always get in the same display: high resolution and high refresh rate.

4K for incredible detail

The 3840 × 2400 resolution provides significantly more pixels than a conventional Full HD gaming display.

That additional resolution can make games look sharper and more detailed, particularly on the SCAR 18's large 18-inch panel.

It's also useful for creative professionals working with high-resolution photos, video and other visual content.

240Hz for smooth gameplay

The 240Hz refresh rate allows compatible games to display significantly more frames per second than a conventional 60Hz or 120Hz panel.

For competitive gamers, this can contribute to smoother motion and a more responsive visual experience.

The display defaults to 120Hz in Standard, Eco and Optimised GPU modes, while 240Hz can be enabled through Armoury Crate when the GPU is set to Ultimate mode.

Mini LED and HDR

The Mini LED panel uses more than 2,000 dimming zones to provide more precise control over brightness across different areas of the screen.

Combined with HDR support, this is designed to deliver brighter highlights, deeper contrast and greater visual depth.

The display also features anti-glare and low-reflection technology to reduce distracting reflections and help maintain image clarity.

The SCAR 18 is also the first ROG laptop to feature ROG Nebula ELMB, a technology designed to improve motion clarity without sacrificing brightness or variable refresh rate functionality.

Designed for gamers and creators

The 16:10 aspect ratio isn't only beneficial for gaming.

The taller display provides additional vertical screen real estate, which can be particularly useful when working with documents, editing timelines, creative applications and other productivity tools.

Combined with 100% DCI-P3 colour coverage and Pantone validation, the SCAR 18 can also appeal to creators who want a gaming laptop that doubles as a capable creative machine.

Whether you're editing video, designing graphics, creating 3D content or gaming, the display is designed to handle demanding visual workloads.

ROG Intelligent Cooling keeps the hardware running

Putting flagship components into a laptop creates an obvious challenge: heat.

The SCAR 18 addresses this with ROG Intelligent Cooling.

The cooling system includes an end-to-end vapor chamber, sandwiched heatsink and Tri-Fan Technology.

The result is a cooling architecture designed to help the CPU and GPU maintain high performance during demanding workloads.

The SCAR 18 can reach up to 95W CPU power and 175W GPU power in Turbo mode, while Manual mode provides additional CPU headroom for users who want to fine-tune performance.

That's particularly important in a gaming laptop because sustained performance can be just as important as peak performance.

Up to 128GB of DDR5 memory

One of the standout features of the new SCAR 18 is its upgradeability.

According to the ROG Strix SCAR 18 G835 specifications, the laptop supports up to 128GB of DDR5-6400 memory through two SO-DIMM slots.

That's far beyond what most gamers will need today.

However, the additional capacity makes the SCAR 18 particularly interesting for power users, creators and professionals who run demanding applications alongside their games.

For example, users working with large datasets, virtual machines, high-resolution media projects or complex creative applications can benefit from additional system memory.

Up to 8TB of storage

Game installations are getting larger.

Modern AAA games can consume well over 100GB of storage, making fast and expandable storage increasingly important.

The ROG Strix SCAR 18 G835 supports two M.2 PCIe slots and can support up to 8TB of storage, including configurations using PCIe Gen 5 SSDs in RAID 0.

That gives gamers plenty of room for a large game library while providing fast storage performance.

More importantly, both the memory and storage are user-upgradeable.

Tool-less upgrades

One of the most practical features of the new SCAR 18 is its approach to upgrades.

ROG has designed the chassis with tool-less access, making it easier to access the memory and SSD slots.

This means the laptop can evolve with your needs.

You could start with a lower storage or memory configuration and upgrade later as your requirements change.

For gamers investing in a premium laptop, this can help extend the useful lifespan of the device.

Thunderbolt 5 connectivity

The SCAR 18 is also built for high-speed connectivity.

It includes two Thunderbolt 5 ports, supporting DisplayPort, power delivery and G-SYNC, with data speeds of up to 120Gbps.

The laptop also includes:

• HDMI 2.1
• Three USB 3.2 Gen 2 Type-A ports
• 2.5G LAN
• 3.5mm combo audio jack

This makes it possible to connect multiple peripherals, external displays, high-speed storage and networking equipment.

For a desktop replacement setup, that connectivity can be particularly useful.

Wi-Fi 7 and 2.5G Ethernet

Online gaming requires a reliable network connection.

The SCAR 18 supports Wi-Fi 7 as well as a 2.5G LAN connection.

Wi-Fi 7 provides the latest generation of wireless connectivity, while 2.5G Ethernet gives gamers a high-speed wired option when maximum network stability is required.

For competitive gaming, connecting through Ethernet can be particularly useful when latency and connection stability matter.

A gaming design built for ROG fans

Performance isn't the only thing that defines the SCAR series.

The ROG Strix SCAR 18 G835 features per-key RGB lighting, an Aura Sync light bar and AniMe Vision lighting.

The AniMe Vision system adds customisable visual elements to the chassis, allowing gamers to personalise the laptop.

The result is a machine that looks like a gaming laptop rather than trying to hide its gaming identity.

A full-size gaming experience

An 18-inch laptop sits at the larger end of the gaming laptop market.

That's intentional.

The larger chassis gives ROG more room for powerful hardware, cooling and a large display.

The SCAR 18 weighs approximately 3.73kg and measures 39.9 × 29.8 × 2.35–3.50cm.

This isn't designed to be the laptop you carry around all day.

Instead, it's aimed at gamers who want something closer to a desktop replacement that can still be moved when necessary.

A 90Wh battery

The SCAR 18 is equipped with a 90Wh battery.

As with any high-performance gaming laptop, actual battery life will vary depending on what you're doing.

Gaming on battery power will naturally place significantly more demand on the system than browsing the web or watching video.

For demanding gaming sessions, the 450W power adapter is designed to provide the power required by the high-performance CPU and GPU configurations.

Windows 11 Pro

The South African G835 configurations listed by ASUS include Windows 11 Pro, providing access to the full PC gaming ecosystem alongside professional productivity features.

Windows 11 provides access to popular game launchers, PC Game Pass and a huge range of gaming and creative applications.

The SCAR 18 also includes support for Xbox Game Pass Premium, with the South African specification page currently listing a two-month offer in eligible markets.

More than a gaming laptop

Although the SCAR 18 is clearly designed around gaming, its hardware makes it capable of much more.

The combination of a 24-core processor, up to RTX 5090 graphics, high-capacity memory and fast storage makes it suitable for:

It's particularly well suited to:

Competitive gamers
The 240Hz display, fast response time, G-SYNC and high-end NVIDIA GPU make the SCAR 18 a compelling option for competitive gaming.
