16-inch 2.5K OLED gaming laptop

The ASUS ROG Zephyrus G16 GU605CX in Platinum White pairs a 16-core Intel Core Ultra 9 285H processor with an NVIDIA GeForce RTX 5090 GPU carrying 24 GB GDDR7 video memory. A 16.0" 2560 x 1600 OLED panel runs at 240 Hz. The system ships with 64 GB LPDDR5X 7467 memory and 16 TB of PCIe 4.0 NVMe storage across two 8 TB drives. Windows 11 Pro is pre-installed.

Verify power and peripheral needs

The chassis measures 13.94" x 9.69" x 0.59" ~ 0.65" and weighs 4.08 lbs. Confirm your workspace accommodates these dimensions and that your power source can sustain the 285 H processor with 5.4 GHz max turbo and the RTX 5090 under load. Check that any external monitors support the laptop's video outputs and that your bag or sleeve fits the 16-inch form factor.

Thermal upgrades and validated build

HIDevolution applies Thermal Grizzly Conductonaut on the CPU and Gelid GC Extreme on the GPU to lower operating temperatures. Every unit receives a full quality check: latest stable BIOS and drivers, burn-in stress testing for thermals, benchmark validation, keyboard and touchpad verification, port functionality, display inspection and physical chassis review. The BTO warranty covers the applied upgrades.

Questions about this item

What comes in the box and what must be purchased separately?

The laptop ships with Windows 11 Pro installed, 64 GB LPDDR5X memory soldered on board, and two 8 TB PCIe 4.0 NVMe SSDs totalling 16 TB. No RAM or storage upgrades are required.

Which configuration should I choose for the display and graphics?

This single SKU pairs a 16 inch 2.5K 240Hz OLED panel with an RTX 5090 carrying 24 GB GDDR7, so there is no alternative screen or GPU to select.

How does the 5.4 GHz turbo frequency behave under sustained gaming loads?

The 16 core Ultra 9 285H can reach 5.4 GHz on boost; HIDevolution applies Conductonaut on the CPU and Gelid GC Extreme on the GPU to keep temperatures lower during extended sessions.
