ROG Zephyrus 16.0" 240Hz OLED

The ASUS ROG Zephyrus GU605CW is a 16.0 inch gaming laptop built around a 240Hz OLED panel at 2560x1600 resolution. It targets users who want high refresh rates and colour accuracy in a portable chassis. The system pairs an Ultra 9-285H processor with an NVIDIA GeForce RTX 5080 16GB GDDR7 GPU for demanding workloads.

240W PSU and 90 WHr battery

A 240W power supply feeds the CPU and GPU combination while a 4-cell 90 WHr battery handles mobile use. The 16-core 16-thread processor reaches 5.4GHz turbo frequency with 24MB cache. Thermal output and fan noise will scale with the 240Hz panel and discrete graphics load during extended sessions.

Thunderbolt 4 and Duex Max monitor

One Thunderbolt 4 port and a USB 3.2 Type-C connector support external displays and high-speed peripherals. An SD card reader and combo audio jack round out the I/O. The bundle includes a Mobile Pixels Duex Max 14-inch FHD secondary screen that attaches for dual-monitor workflows. Onboard 32GB LPDDR5X memory is not upgradeable.

Questions about this item

How is the 32 GB LPDDR5X memory installed, and what mistake do people make?

The memory is soldered to the motherboard and cannot be upgraded or replaced. The common mistake is buying SO-DIMM modules expecting to add capacity.

What maintenance will the 90 Whr battery need later?

The 4-cell 90 Whr battery is internal and not user-replaceable. When capacity degrades, service by a qualified technician is required.

What limit appears first during sustained loads on the RTX 5080 with 16 GB GDDR7?

The 240 W power adapter caps combined CPU and GPU draw, so the GPU will throttle before thermal limits are reached.
