The Asus ROG Zephyrus S is made up of plastic with a matte black finish. Asus also did some excellent jobs in hiding the fingerprint smudges on its exterior.

It is also considered lightweight as it only weighs around 2kg so you can just carry it with one hand as it is very light. The design is overall simple and elegant, a black-themed with several branding elements on the exterior and interior.

Top marks for those who noticed the absence of a webcam. We’ve seen laptop vendors move the built-in camera below the display in order to facilitate ultra-thin bezels, but Asus has gone a step further by removing the webcam altogether. An odd choice, and though Asus does bundle the laptop with an external camera in select markets, not having a built-in solution in a premium machine such as this is a major oversight.

GX502 does, however, have something most competitors don’t; an ‘Active Aerodynamic System’ (AAS) built into the base of the magnesium-alloy chassis. In keeping with earlier Zephyrus models, AAS raises the rear of the laptop up 7mm by flexing the bottom panel when the lid is opened. Asus reckons the end result is a 22 percent increase in airflow for the two internal fans, and there’s an added benefit in that the keyboard is automatically raised to a more comfortable incline.

Another thing to keep in mind is that the fans can be loud. When it runs at high speeds (around 5,000 to 6,000 rpm), fan noise can go up to a maximum of 46.8 dBa. In short, you’ll definitely notice the sound from the fans.

The keyboard features a 16.8m RGB programmable lighting with a bunch of multimedia and function keys that can be executed using different key commands. The touchpad is a big improvement over previous models. It’s large and responsive, and even the click mechanism feels solid. The lighting is handled by ROG’s AuraSync technology, which provides per-key RGB backlighting with plenty of room for customization.

I/O Ports and Battery

The ROG Zephyrus GX502G features a 3x USB-A 3.1, 1x USB-C gen 2 with DP and charging, HDMI 2.0b, LAN, headphone/mic.

The selection of those ports will prevent you from using an external sort of USB hub and different kinds of docks.

Now, we conduct the battery tests with Windows Better performance setting turned on, screen brightness adjusted to 120 nits and all other programs turned off except for the one we are testing the notebook with. Similarly to its 17-inch compatriot – the ROG Zephyrus S GX701, the GX502 is equipped with a 76Wh battery pack. We found the laptop to be capable of providing around 6 hours of Web browsing time and 5 hours of video playback, only on battery power.


GX 502G is equipped with a 15.6 inches display with a super-fast 240Hz refresh rate as standard. The Display panel is also G-Sync which can be considered top-choice for gamers. Great for those who prefer higher refresh rates especially in fps games which requires you to respond quickly.

Viewing angles are excellent and color reproduction is great and can be viewed perfectly even under bright lighting. When it comes to performance, the key highlight for the GX502 is definitely the 240Hz display. The powerful hardware ensured that we got to experience absolutely stutter-free visuals for a lot of games, especially for games like CS; GO or Apex Legends. The other two aspects of the display we found great were the color reproduction and the thin bezels, which enables for a more seamless viewing experience.


The Pre-installed “ROG Armoury Crate” software comes in handy as it has some sort of necessary features that you can access with just a few clicks. The GX502 can also toggle between G-Sync and Optimus. G-Sync is Nvidia’s adaptive sync technology that prevents screen tearing, which makes games look smooth at higher framerates. However, it kills battery life fast because it requires the GPU to be engaged at all times. Optimus mode allows the system to switch between the Nvidia GPU and Intel integrated graphics, meaning you’ll save hours of battery life when you aren’t gaming. Past laptops could only offer one or the other, but on Asus’ recent ROG laptops, you can toggle between the two.

The fan profiles were linked to system power profiles, making for an easy one-click switch between low-power mode up to high-performance setup.

You can also configure the lightings in the whole laptop and sync every light along with a selection of lighting animations.


We’d tested the Asus ROG Zephyrus S GX502G using different benchmarking tools and the result we’d got is more than great coming from a powerhouse Intel Core i7 9750h paired with the Nvidia RTX 2070.

The Asus ROG Zephyrus S GX502G can be considered as a top choice when buying a gaming laptop as it is a small-form-factor/compact powerhouse that can run almost all games in highest settings with great frames per second thanks to its graphics card which is the Nvidia RTX 2070. The 6-core/12-threads Intel Core i7-9750H processor will also help in rendering faster than the usual 4-core/8-threads processor in the market.
