18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 G815LW is an 18-inch gaming laptop built around an Intel Core Ultra 9-275HX processor with 24 cores and a 5.5 GHz maximum turbo frequency. It pairs that CPU with an NVIDIA GeForce RTX 5080 graphics card carrying 16 GB of GDDR7 memory. The system runs Windows 11 Home on 32 GB of DDR5 5600 MHz memory in dual-channel configuration. A 2 TB PCIe 4.0 x4 NVMe SSD provides the primary storage.

Buyers who need desktop-class performance

This machine suits users who want a 2.5K 240Hz IPS-level display and the thermal headroom provided by Gelid GC Extreme on the GPU and Conductonaut on the CPU. The 7.54 lb weight and 15.71 by 11.73 inch footprint make it a poor fit for frequent travel or compact workspaces. Anyone prioritising all-day battery life or a thinner profile should look at smaller ultraportable alternatives.

RTX 5080 with 16 GB GDDR7 decides the tier

The graphics card is the single specification that determines whether this laptop matches a workload. Sixteen gigabytes of GDDR7 memory paired with the RTX 5080 architecture sets the ceiling for 1440p and 4K gaming, real-time rendering and GPU-accelerated compute. If a workflow does not require that level of video memory or compute throughput, a lower-tier GPU will cost less and run cooler.

Questions about this item

What power adapter wattage does the G815LW require for the Ultra 9-275HX and RTX 5080?

The laptop ships with a power adapter sized for the 24-core Ultra 9-275HX and RTX 5080 with 16 GB GDDR7 to sustain 5.5 GHz turbo clocks.

Can I keep my existing DDR5 5600 SODIMMs when upgrading this 32 GB dual-channel kit?

The system runs 32 GB of DDR5 5600 in two 16 GB modules; matching capacity and speed avoids down-clocking the memory controller.

How do I verify the WQXGA panel is running at 240 Hz after driver installation?

Open Windows display settings or the NVIDIA control panel and confirm the refresh rate shows 240 Hz at 2560 x 1600 resolution.
