18-inch UHD+ Mini LED display

The 18-inch panel delivers a 3840 by 2400 resolution at 120 Hz using Mini LED backlighting. This configuration targets gamers and creators who need high pixel density and smooth motion in a single chassis. The display size and refresh rate suit competitive play and colour-critical workflows alike.

Gelid GC Extreme thermal interface material

HIDevolution applies Gelid GC Extreme on the CPU and GPU to lower core temperatures under load. The upgrade aims to reduce throttling during sustained gaming or rendering sessions while keeping fan noise in check. Power draw remains governed by the stock 16-core Ryzen 9 9955HX3D and RTX 5080 16 GB GDDR7 limits.

Dual 4 TB PCIe 4.0 NVMe and 64 GB DDR5 6400 MHz

The storage array combines two 4 TB drives for 8 TB total capacity on PCIe 4.0 x4 lanes. Memory ships as two 32 GB modules running at 6400 MHz in dual-channel mode. Windows 11 Pro is pre-installed with updated BIOS, drivers and a full burn-in validation before shipment.

Questions about this item

Will the 18-inch UHD+ Mini LED display fit in a standard 15.91 by 12.09 inch laptop sleeve?

The chassis measures 15.91 inches wide by 12.09 inches deep, so a sleeve sized for those external dimensions will accommodate it.

Can the 64 GB DDR5 6400 MHz memory be expanded beyond the factory 2 x 32 GB configuration?

The system ships with both SO-DIMM slots populated at 64 GB total; further expansion would require replacing the existing modules.

Does the 8 TB PCIe 4.0 NVMe storage arrive as a single drive or as the 2 x 4 TB pair installed by the builder?

It is configured as two 4 TB M.2 PCIe 4.0 x4 NVMe SSDs for a combined 8 TB capacity.
