ASUS's 16-inch high-end gaming laptop. It pairs the Core Ultra 9 275HX with an RTX 5090 Laptop GPU running up to 175 W, a 240 Hz Mini LED panel and two Thunderbolt 5 ports. Memory and SSDs can be swapped through a tool-less bottom cover. Tests praise the display and performance; loud fans, a smudge-prone plastic base and short battery life draw criticism.

ASUS says its liquid metal offers 17 times the conductivity of the previous compound with up to 15 °C lower temperatures in internal tests, and that the dual ACR layer improves contrast 4.5 times. These are manufacturer claims. ASUS ROG Strix SCAR 16 (2025) G635
In Notebookcheck's RTX 5090 sample the Mini LED panel measured about 773 cd/m² in SDR and over 1,400 cd/m² in HDR, with SDR contrast around 10,771:1 and PWM at 20,555 Hz. The factory colour profiles were very accurate and local dimming can be switched off. Fan noise while gaming in Turbo reached 53.6 dB(A); the review lists loud fans, no PCIe 5.0, a plastic base that shows smudges and no rear ports as negatives.
Notebookcheck: Asus ROG Strix SCAR 16 (2025) review — RTX 5090 Laptop and mini LEDIn the same test GPU power was 175 W in Turbo, 160 W in Performance and 55 W in Quiet and battery modes. Cyberpunk 2077 at QHD Ultra ran at 46 fps in Quiet and 108 fps in Turbo, so the quiet mode cuts more than half the gaming speed. The review suggests the RTX 5080 model unless the larger VRAM is needed.
Notebookcheck: Asus ROG Strix SCAR 16 (2025) review — RTX 5090 Laptop and mini LEDUltrabookreview's RTX 5080 G635LW sample ran the CPU at 85–90 °C and the GPU at 80–82 °C while gaming in Turbo, with fans around 48 dBA; Silent mode caps the GPU at 55 W. On 100 W USB-C PD the battery drained 20–30 W per hour in games. The keyboard was called “excellent”; the sharp front edge, missing lid lip, 135-degree hinge and weak webcam were criticised. The chassis and keyboard are shared with the G635LX; the GPU results should not be carried over to this model.
Ultrabookreview: Asus ROG Scar 16 G635 reviewIn the same review, battery runs (about 120 nits, 60 Hz, Silent) gave roughly 4 hours of text editing, about 3 hours of 4K HDR Netflix and about 3 hours of browsing with RGB and AniMe on. The author notes these are clearly shorter than the Scar 18 and suspects early drivers, without confirming the cause.
Ultrabookreview: Asus ROG Scar 16 G635 reviewOn the ASUS ROG forum JanhWo, who says they have used a G635LX for about a month, reported that after sleeping unplugged the bottom lighting turned on brightly and stayed on when charged with the lid closed, that opening and closing the lid was the only fix, that the AniMe clock animation keeps scrolling and that one dot stays bright when the brightness is lowered.
