ASUS ROG Zephyrus S17 GX703HS-XB99 identity

This ASUS ROG Zephyrus S17 GX703HS-XB99 is a 17.3 inch gaming laptop built around an 11th Gen Intel Core i9-11900H processor with eight cores and a 4.9 GHz turbo frequency. The system pairs 48GB of DDR4 memory with a GeForce RTX 3080 laptop GPU carrying 16GB of GDDR6 video memory. It targets users who need desktop-class compute and graphics in a portable chassis.

Three four-terabyte PCIe SSD RAID 0 array

Storage consists of three 4TB PCIe NVMe SSDs configured in RAID 0, presenting 12TB of contiguous capacity to the operating system. The striped array raises sequential throughput for large asset ingestion and reduces load times for sprawling project directories. Windows 11 Pro ships pre-installed on the volume so the machine is ready for production workflows immediately.

17.3 inch 4K 120Hz IPS display headroom

The 3840 by 2160 IPS panel refreshes at 120 Hz, giving colour-accurate preview space for 4K timeline scrubbing and high-frame-rate competitive play. Thunderbolt 4 and USB 3.2 Gen 2 Type-C ports supply external GPU or storage expansion when internal thermal or bandwidth ceilings are reached. The 90 WHr battery and 280W adapter sustain moderate workloads away from mains power.

Questions about this item

Can the 32 GB DDR4 SODIMM module be replaced with a higher-capacity stick later?

The laptop uses one 32 GB DDR4 SODIMM alongside 16 GB soldered memory; swapping the module for a larger DDR4 stick is the only way to increase total RAM beyond 48 GB.

Which component hits its thermal ceiling first during extended gaming on the RTX 3080 16 GB GDDR6 GPU?

The 11th Gen Intel Core i9-11900H 8-core processor reaches its 4.9 GHz turbo limit and throttles before the GPU under sustained 4K 120 Hz loads.

How loud do the fans get and what power does the 280 W adapter draw when the 17.3" 3840x2160 120 Hz display runs all day?

Under continuous 4K 120 Hz gaming the cooling system spins up to maximum airflow while the 280 W power supply delivers near its rated output to feed the CPU, RTX 3080 and three NVMe SSDs.
