18-inch WQXGA 240Hz laptop

The ASUS ROG Strix G18 G815LW is an 18-inch gaming laptop with a 2560 x 1600 IPS-level display running at 240Hz. It is powered by an Intel Core Ultra 9-275HX 24-core processor reaching 5.5 GHz and an NVIDIA GeForce RTX 5080 GPU with 16 GB GDDR7 memory. The system includes 64 GB of DDR5 5600MHz memory and 16 TB of PCIe 4.0 x4 NVMe storage. It ships with Windows 11 Pro.

Suits high-refresh competitive play

This configuration suits users who want maximum frame rates at 2.5K resolution and need large memory capacity for content creation or virtualization. The factory-applied Gelid GC Extreme thermal compound on the GPU and Conductonaut on the CPU target sustained performance under load. Buyers who prioritise thin-and-light portability or lower power consumption should look at smaller form factors.

16 TB NVMe storage and 64 GB DDR5 headroom

The dual 8 TB NVMe drives provide extensive space for large game libraries, project files and datasets without relying on external drives. The 64 GB dual-channel DDR5 kit handles memory-intensive workloads such as 3D rendering, video editing and multiple virtual machines. The 16 GB GDDR7 frame buffer on the RTX 5080 supports high-resolution textures and compute tasks, while the 24-core CPU delivers throughput for parallel processing.

Questions about this item

What power adapter is required for the 5.5 GHz Ultra 9-275HX and RTX 5080 to run at full load?

The laptop ships with a high-wattage AC adapter sized for the 24-core CPU and 16 GB GDDR7 GPU; the exact wattage is printed on the brick included in the box.

Will my existing PCIe 3.0 NVMe drives work in the second M.2 slot if I keep the 16 TB RAID array as the boot drive?

The platform supports PCIe 4.0 x4 NVMe; a PCIe 3.0 drive will function in the spare M.2 slot at its native speed without affecting the 2 x 8 TB boot array.

How can I verify the 240 Hz WQXGA panel and 64 GB DDR5 5600 are active after Windows 11 Pro boots?

Open Settings > System > Display and confirm 2560 x 1600 at 240 Hz, then open Task Manager > Performance > Memory and confirm 64 GB DDR5 5600 running dual-channel.
