18-inch UHD+ Mini LED display

The 18-inch panel delivers a 3840 by 2400 resolution at a 120 Hz refresh rate using Mini LED technology. High pixel density and fast response suit creative work and competitive gaming alike. Bright highlights and deep contrast arrive without an external monitor.

Intel Core Ultra 9 285HX with RTX 5090

A 24-core processor reaches 5.5 GHz maximum turbo alongside the mobile RTX 5090 with 24 GB GDDR7 memory. Gelid GC Extreme thermal compound replaces stock paste on both chips to lower peak temperatures. The design frees thermal headroom for sustained workloads without adding external cooling.

32 GB DDR5 and 8 TB NVMe storage

Dual-channel 5600 MHz DDR5 totals 32 GB for memory-intensive applications and multitasking. Two 4 TB PCIe 4.0 NVMe drives combine for 8 TB of fast storage, eliminating the need for secondary drives. Capacity covers large project libraries, though the 32 GB RAM ceiling may limit extreme virtualization or dataset work.

Questions about this item

What thermal limit does the Intel Core Ultra 9-285HX hit first during long gaming sessions?

The 24-core processor reaches its 5.5 GHz turbo ceiling before sustained loads push temperatures high enough to throttle, so clock speed is the first bound you encounter.

How loud and hot does the chassis get when the RTX 5090 runs at full load all day?

Gelid GC Extreme paste on both CPU and GPU keeps core temperatures lower than stock, letting fans stay at moderate RPM instead of spinning to maximum.

Which DDR5 memory kit must already be installed for the 5600 MHz dual-channel speed to work?

The system ships with 32 GB configured as 2 x 16 GB DDR5 5600 MHz modules, so no additional memory purchase is required.
