Overview

Processor & Graphics

The ASUS ROG Strix Scar 18 G835LWG-TQ363WS is powered by the Intel Core Ultra 9 290HX processor, running at a 2.7GHz base clock with a turbo frequency up to 5.5GHz, backed by 36MB of cache across 24 cores and 24 threads. An Intel AI Boost NPU rated up to 13 TOPS handles on-device AI workloads.

Graphics are handled by an NVIDIA GeForce RTX 5080 Laptop GPU with 16GB GDDR7 memory. ROG Boost pushes clocks up to 1550MHz at 175W total graphics power, combining a 1500MHz boost clock plus 50MHz overclock, with 150W base power and 25W of Dynamic Boost. A MUX Switch paired with NVIDIA Advanced Optimus routes the display directly to the discrete GPU when needed.

Memory & Storage

The configuration ships with 32GB of DDR5-6400 memory across two SO-DIMM slots running in dual-channel mode, with support for up to 128GB total across the two slots. Storage is a 1TB PCIe 4.0 NVMe M.2 Performance SSD, with two M.2 PCIe slots available in total for expansion.

Display

The 18-inch ROG Nebula HDR display uses a Mini LED panel at 4K WQUXGA resolution (3840×2400) in a 16:10 aspect ratio, with an anti-glare and low-reflection (AGLR) coating. Color coverage reaches 100% DCI-P3, and the panel carries Pantone Validation.

Refresh rate runs at up to 240Hz, though the display defaults to 120Hz in Standard, Eco, and Optimized GPU modes — reaching 240Hz requires switching to Ultimate GPU mode through Armoury Crate. The panel supports NVIDIA G-Sync for variable refresh rate.

Connectivity & I/O

Wireless connectivity includes Wi-Fi 7 (802.11be) on a triple-band 2×2 configuration paired with Bluetooth 5.4.

  • 3x USB 3.2 Gen 2 Type-A, data speed up to 10Gbps
  • 2x Thunderbolt 5 with DisplayPort, power delivery, and G-Sync support, data speed up to 120Gbps
  • 1x HDMI 2.1 FRL
  • 1x 3.5mm Combo Audio Jack
  • 1x 2.5G LAN port

Battery & Power

A 90Wh, 4S1P, 4-cell Li-ion battery powers the ASUS ROG Strix Scar 18 G835LWG-TQ363WS, paired with a 450W AC adapter. The adapter outputs 21V DC at 21.45A and accepts 100-240V AC input at 50/60Hz.

Build & Form Factor

The chassis weighs 3.70 Kg (8.16 lbs) and comes in a Black colorway. Lighting is handled through Aura Sync, covering the Aura Sync logo, an Aura Sync Light Bar, and the AniMe Vision display panel.

Input comes from a backlit chiclet keyboard with per-key RGB lighting and a dedicated Copilot key, alongside a touchpad. A 1080P FHD IR camera supports Windows Hello for biometric sign-in. Audio runs through a 4-speaker system with Smart Amp Technology, Hi-Res certification for headphones, Dolby Atmos, AI noise-canceling, and a built-in array microphone.

Software

The laptop runs Windows 11, bundled with M365 Basic for one year, Office 24, and a 30-day McAfee trial.

Security

Security features include a firmware Trusted Platform Module (TPM), along with BIOS administrator and user password protection.
