Platinum White 16-inch OLED Gaming Laptop

The ASUS ROG Zephyrus G16 GU605CX is a Platinum White gaming laptop built around a 16.0-inch 2.5K OLED panel running at 240 Hz. It ships with Windows 11 Pro and targets users who want high-refresh HDR visuals in a 4.08 lb chassis measuring 13.94 x 9.69 x 0.59~0.65 inches.

64 GB LPDDR5X and 4 TB NVMe Storage

The system integrates 64 GB of LPDDR5X 7467 dual-channel memory soldered to the board, leaving no SO-DIMM slots for expansion. A 4 TB M.2 PCIe 4.0 x4 NVMe SSD handles the operating system and game library, while the thin profile relies on vapor-chamber cooling enhanced with Gelid GC Extreme on the GPU and Conductonaut on the CPU.

RTX 5090 with 24 GB GDDR7 and Ultra 9 285H

The NVIDIA GeForce RTX 5090 mobile GPU brings 24 GB of GDDR7 video memory for 4 K gaming and creative workloads. The Intel Core Ultra 9 285H 16-core processor boosts to 5.4 GHz with 24 MB L3 cache, delivering headroom for heavy multitasking; sustained loads will be limited by the slim thermal envelope.

Questions about this item

What happens when the Intel Core Ultra 9-285H hits its 5.4 GHz turbo ceiling during long sessions?

The processor reaches its maximum turbo frequency of 5.4 GHz under load, and the Gelid GC Extreme thermal compound on the GPU helps maintain stable temperatures during sustained operation.

How loud or hot does the RTX 5090 with 24 GB GDDR7 get when running all day?

The GPU uses Gelid GC Extreme thermal interface material applied by the builder, which lowers graphics-chip temperatures and keeps fan noise reduced during extended workloads.

Which external display cable do I need for the 16" 2560 x 1600 240 Hz OLED panel?

The built-in screen is driven internally; for an external monitor use the laptop's HDMI or USB-C video outputs with a cable that matches your display's input.
