ASUS Republic of Gamers (ROG) Zephyrus S GX531 First Impression

ASUS Republic of Gamers (ROG) announced Zephyrus S GX531 in India. At a mere 14.95~15.75mm thin, Zephyrus S is 12% slimmer than the original Zephyrus (GX501). It’s equipped with the latest Intel Core i7-8750H CPU and up to NVIDIA GeForce GTX 1070 Max-Q graphics. Narrow bezels squeeze a 15.6-inch display, with a 144Hz refresh rate and 3ms response time, into a 14.2-inch chassis. The all-metal chassis is strong enough to meet military-grade durability standards without compromising on design, with sleek lines and a premium finish. An advanced cooling system ensures optimal performance of all components, incorporating the proprietary Active Aerodynamic System (AAS) — a design and engineering hallmark of the Zephyrus series.

Design

Zephyrus S uses a mix of aluminum and magnesium alloys in its construction to achieve this balance. Each lid is meticulously machined from a solid block of aluminum. This precise CNC-milling process takes five tooling stages and nearly 72 minutes to carve out all the intricate details that ensure a perfect fit, creating a lid that is remarkably rigid, yet slim. It also helps the Zephyrus S casing remain durable: engineering samples have already met military-grade durability standards for jolts and vibration.

Contrasting finishes accentuate the lid design: two-stage anodizing accents the stealthy surfaces with copper highlights, while a surgical slash separates competing textures. Similar lines cut across the area above the keyboard, giving Zephyrus S a distinctive style. Scissor-door hinges keep a low profile until the laptop is opened, exposing the display and opening Zephyrus’ unique air intake.

Display

Narrow bezels allow the 15.6-inch display to be squeezed into a 14.2-inch chassis. This reduces the entire footprint, allowing the Zephyrus S to fit into tighter spaces than its predecessor. In addition, the slimmer bezels create a more immersive gaming experience.

The 120Hz panel on the initial version doubled the refresh rate of conventional displays, while Zephyrus S pushes the refresh rate to 144Hz, and reduces blurring and ghosting by lowering the response time to 3ms.

The IPS-type AHVA panel also has excellent image quality. It covers 100% of the sRGB color gamut, ensuring richness of color, and wide viewing angles keep the picture from washing out when viewed in split screen.

Performance

Cooling the critical components that comprise Zephyrus S is a difficult engineering feat due to the ultrathin design, but it’s imperative to ensure peak performance. Because of this, ASUS and ROG thermal engineers developed the innovative Active Aerodynamic System (AAS) for the original Zephyrus. When the lid of the laptop is lifted, a special vent opens underneath the chassis to let the laptop draw in more cool air. Similarly, the AAS intake measures 5mm on Zephyrus S, stretching across the entire back of the body to improve airflow by 22% compared to traditional designs. Additional airflow comes in from through the keyboard, and the keyboard’s forward layout makes more room for additional cooling throughout the system.

Within the chassis, the Zephyrus S contains five heat pipes that pull heat away from the CPU and GPU, and also the VRM circuitry that feeds them power. The CPU and GPU connect to both shared and dedicated heatsinks to ensure efficient cooling for any workload, and the power components stay under 80°C to improve long-term reliability. Thermal energy is channeled along the pipes to four heatsinks and exhaust vents at the rear corners, twice as many as in the first Zephyrus.

Keeping heatsinks free of dust and debris is key to preserving cooling performance, which is why the engineering team added self-cleaning fans to eject particles from the system through anti-dust tunnels. This special feature prevents accumulation on the fins to ensure consistent cooling and improve long-term stability.

With 83 blades each, the dual 12V AeroAccelerator fans have 17% more blades than in the original Zephyrus. Airflow is also improved by the fan’s shaped aluminum shroud, which has curved edges and raised guides to help channel more air into the blades. Rotational speeds are determined by an intelligent algorithm tied to three profiles. Keyboard shortcuts allow users to switch between Overboost mode for maximum gaming performance, Silent mode for lower acoustics, and Balanced mode that maintains a level between the two.

Keyboard

Although the keyboard-forward layout on Zephyrus S primarily benefits cooling, it also allows for a more comfortable desktop-like resting position. Overstroke technology fires earlier in the key travel for quicker responsiveness and the longer post-actuation distance maximizes the 1.2mm of travel to improve the overall typing feel. The durable switches are rated for 20 million presses, so they can withstand heavy use, and N-key rollover ensures each press registers precisely regardless of how many keys are mashed at once.

Storage and connectivity

The Intel Core i7-8750H CPU in Zephyrus S is backed by fast DDR4 2666MHz memory and NVMe storage, while 802.11ac Wave 2 Wi-Fi connects to compatible wireless networks at greater-than-gigabit speeds. USB 3.1 Gen 2 Type-C (USB-C) and full-size HDMI 2.0 ports support desktop monitors and big-screen TVs, allowing users to connect dual auxiliary displays. More USB ports are ready for essential gaming peripherals and ubiquitous external storage, and there’s a USB 3.1 Gen 2 Type-A port offering additional bandwidth for compatible devices.
