Why this product
Core Ultra 9 290HX Plus, 24 cores
2.7 GHz base rising to 5.5 GHz, 24 cores and 24 threads with 36 MB of cache, plus an on-die NPU rated at 13 TOPS.
RTX 5080 16 GB at up to 175 W
GeForce RTX 5080 Laptop GPU with 16 GB of GDDR7, boosting to 1550 MHz at a 175 W total graphics power with ROG Boost.
18-inch Mini LED at 3840 x 2400
ROG Nebula HDR panel, 240 Hz, 100% DCI-P3, NVIDIA G-SYNC and Pantone validation. Non-touch.
2 TB in RAID 0, memory to 128 GB
Two 1 TB PCIe 4.0 NVMe drives striped as a single 2 TB volume. The 32 GB of DDR5 sits in two SO-DIMM slots and can be taken to 128 GB.
MUX switch with Advanced Optimus
The display can be driven straight from the RTX 5080 rather than through the integrated graphics, and switches automatically.
Thunderbolt 5 and 2.5 Gb Ethernet
Two Thunderbolt 5 ports, HDMI 2.1 FRL, three USB 3.2 Gen 2 Type-A, 2.5 Gb LAN, Wi-Fi 7 and Bluetooth 5.4.

- 32 GB of DDR5 fitted across two SO-DIMM slots, upgradeable to a maximum of 128 GB.
- Two M.2 PCIe 4.0 slots, both occupied by 1 TB drives configured as RAID 0.
- Charges over USB Type-C Power Delivery at 45 W to 100 W as well as from the supplied 450 W adapter.
- Replacement M.2 SSDs must be single-sided; double-sided drives do not fit the bays.
- The panel runs at 120 Hz by default. The full 240 Hz requires the GPU mode to be set so the display is driven directly by the RTX 5080, which needs a restart.
- The 2.5 Gb RJ-45 port does not supply or accept Power over Ethernet.
Best for
- Gaming at the panel's native 3840 x 2400 with the GPU given its full 175 W.
- Work that uses every core: rendering, compiling, video export, simulation.
- A desk-bound main machine where the 450 W adapter is always to hand.
- Wired networking at 2.5 Gb and Thunderbolt 5 docking.
Trade-offs
- Carrying around all day: 3.70 kg before you add a 450 W power brick.
- Running demanding work off the battery: a 90 Wh battery against a 175 W graphics card means mains power for anything heavy.
- Double-sided M.2 upgrades: only single-sided SSDs fit.
- Touchscreen use: the Mini LED panel is not a touch display.
The ASUS ROG Strix SCAR 18 G835LWG-TQ313W is an 18-inch gaming laptop built around a 24-core Intel Core Ultra 9 290HX Plus and an NVIDIA GeForce RTX 5080 Laptop GPU with 16 GB of GDDR7. The graphics card is allowed a 175 W total graphics power and boosts to 1550 MHz with ROG Boost, and a MUX switch with NVIDIA Advanced Optimus lets the panel be driven directly by the RTX 5080 rather than through the integrated graphics.
The 18-inch ROG Nebula HDR display is a Mini LED panel running 3840 x 2400 at 240 Hz, covering 100% of DCI-P3, with NVIDIA G-SYNC and Pantone validation. It is not a touchscreen. Note that the machine ships at 120 Hz and the full 240 Hz becomes available once the GPU mode is set so the display is driven directly by the discrete graphics, which requires a restart.
Memory is 32 GB of DDR5 in two SO-DIMM slots with a 128 GB maximum, so it can be expanded later. Storage is 2 TB, made up of two 1 TB PCIe 4.0 NVMe drives striped in RAID 0; replacement drives must be single-sided. Connectivity runs to two Thunderbolt 5 ports, HDMI 2.1 FRL, three USB 3.2 Gen 2 Type-A, a 2.5 Gb Ethernet port, a 3.5 mm combo jack, Wi-Fi 7 and Bluetooth 5.4. The RJ-45 port does not carry Power over Ethernet.
The keyboard is per-key RGB backlit with a numeric keypad, and the camera is 1080p with infrared for Windows Hello. The 90 Wh battery is served by a 450 W adapter, with USB-C Power Delivery charging supported from 45 W to 100 W. Windows 11 Home, Off Black, 3.70 kg. ASUS part number 90NR0LI1-M00E20.
