18-inch Mini LED 4K 120Hz display

This gaming laptop pairs an 18-inch Mini LED panel at 3840x2400 with a 120Hz refresh rate for high-detail visuals. The Intel Core Ultra 9 275HX reaches 5.4GHz across 24 cores and 24 threads, supported by 64GB of DDR5 SO-DIMM memory. An NVIDIA GeForce RTX 5090 with 24GB GDDR7 provides dedicated graphics power. The system includes an 8TB PCIe NVMe SSD and ships with Windows 11 Home.

Suited for stationary high-performance workloads

The 7.6lb chassis and 400W power supply make this unit best for desk-bound creators, engineers, or gamers who need desktop-class compute and a large colour-accurate screen. Buyers who prioritise portability, all-day battery life, or a smaller footprint should consider lighter alternatives. The 99 WHr battery and 1.25-inch profile are built around sustained AC performance rather than mobility.

8TB PCIe NVMe SSD capacity

The single specification that decides fit is the 8TB PCIe NVMe SSD. It determines whether the laptop can hold large project libraries, game collections, or dataset caches without external storage. If the workload fits within a smaller drive, a lower-capacity configuration may be more cost-effective; if it exceeds this limit, external expansion will be required.

Questions about this item

How do I install the 64GB DDR5 SO-DIMM modules and what step do people get wrong?

The laptop uses DDR5 SO-DIMM slots. The common mistake is buying standard DIMM sticks instead of the shorter SO-DIMM form factor, which will not fit.

What maintenance or replacement will the 99 WHr 4-cell battery need later?

The 99 WHr battery is a 4-cell pack that will lose capacity over time; plan to replace the entire pack when runtime drops below your needs.

What limit shows up first on the RTX 5090 24GB GDDR7 under sustained load?

The 400W power supply caps total system draw, so the GPU will hit its power limit before thermal throttling becomes the primary bottleneck.
