If you are looking for the next generation of ZenBook, then you can check out the ASUS ZenBook 3 UX390UA, which is said to be re-imagined for the next era of mobile computing, where each precision component and detail is carefully crafted, re-designed and re-engineered to make the machine as sophisticated as possible.

Details of  ASUS ZenBook 3 UX390UA


Like other ASUS ZenBooks, the UX390UA comes with a unique and stunning look, which will be instantly recognized with the iconic spun-metal finish on its uni-body metal enclosure. Aside from this, it is added with a beautiful twist through a two-phase anodizing process, creating a stunning golden edge highlight. While it is thin and light, like its predecessors, its design is taken to another level, making it even lighter and thinner using premium, aerospace-grade aluminum, which is also 50% stronger than the usual material used before. It has a lightweight, ultra-slim, yet very durable, display, which is covered with 0.4 millimeters of super-strong Corning Gorilla Glass 4.

As for its typing features, this ZenBook laptop sports a full-size backlit keyboard that stretches from edge to edge, and has a 2.1-millimeter bezel at each side and a key pitch of 19.8 millimeters, which is generally similar with most desktop keyboards. And while the keyboard is designed to be incredibly slimmer than the previous generation, it still has an impressive 0.8-millimeter key travel. Moreover, it comes with a precision touchpad that is cleverly engineered for maximum accuracy and comfort, with a glass covering for smooth control, Smart Gestures technology, palm-rejection functionality and handwriting support.


When creating the ASUS ZenBook 3, Asus has seemed to overcome the challenge of combining high-performance parts into the smallest chassis yet for the ZenBook family, resulting in an incredibly powerful laptop that uses the latest Intel Core i7 processor, an ultra-fast 512GB PCIe Gen 3 SSD, 16GB of 2133MHz LPDDR3 RAM and the latest USB-C port that supports display. With the powerful processor inside a slim chassis, engineers of this laptop had to create a new cooling system with the use of state-of-the-art components, such as a copper-alloy heat pipe with merely 0.1-millimeter thick walls and a liquid-crystal-polymer fan impeller that is just 0.3 millimeters thick. This innovative addition gently routes the warm air through hidden vents in the device’s hinge for quiet and efficient cooling function even it is being used under full load.

This laptop is also given unsurpassed audio capabilities by the ASUS Golden Ear team using the next generation of SonicMaster audio technology, leading to astonishing results. It uses 4 separate high-quality speakers that are powered by a smart 4-channel amplifier that produces true surround-sound that will delight you with cinema-quality and distortion-free realism.

In spite of having an ultra-slim design, this ASUS ZenBook 3 amazingly offers a battery life that lasts throughout the day, as it uses a special high-capacity 40Wh lithium-polymer battery that is specially designed to precisely fit into the laptop’s extremely thin profile. In addition, it uses a fast-charging technology that allows charging of up to 60% capacity in just less than 50 minutes.

Accessing the ASUS ZenBook 3 UX390UA is also more secure and very easy, with its fingerprint sensor built on the touchpad and its Windows Hello feature, which no longer requires you to type in your password each time you log into the device. All it takes to unlock this ZenBook is just a single touch, which is as effortless as a smartphone.

Considering all the performance features of this laptop, you no longer need to worry about what you can or cannot do with it.


Using the Intel HD graphics processing unit (GPU), the ASUS ZenBook 3 UX390UA will bring you the ultimate visual experience, harnessing the power of the manufacturer’s exclusive display technologies combined with optimized software and hardware components to deliver the best possible images. Its TV-grade 1000:1 contrast ratio, wide 72% NTSC color gamut and Asus Splendid technology (which fine-tunes display parameters) ensure that you will get more vivid, accurate and life-like colors for any type of image. Its ASUS Tru2life video enhancement technology optimizes the appearance of every pixel in each video frame to deliver pinpoint sharpness and 200% better contrast. And paired with a newly designed display, with ultra-slim bezel that is just 0.3 inches wide, this laptop will offer improved clarity and form factor, most importantly giving you a distraction-free view of its stunning 12.5-inch full HD screen. Moreover, it has wide 178-degree viewing angles, crisp detail and superb color reproduction.

Pros and Cons

Pros of ASUS ZenBook 3 UX390UA

  • Generally, this is a fast and very light laptop, so you will be impressed by its capability to be carried and transported easily even in its leather case.
  • With blazing-fast 7th-generation 2.5GHz Intel Core i5-7200U processor, this device can deliver a 10% to 15% increase in overall performance and power compared to its 6th-generation predecessor, which is even boosted by a substantial enhancement in its 4K video playback and decoding capability.
  • It runs on Windows 10 Pro, meaning that you will have the most flexibility from an OS, which is great especially if you are an IT professional.

Cons of ASUS ZenBook 3 UX390UA

  • The typing experience on this laptop is not that smooth, partly due to its shallow 0.8-millimeter key travel, resulting to a tactile feedback that is less than optimal. Basically, the keyboard is just too small in terms of spacing, which means that you will not get used to it if you are a touch typist.
  • Having only one connectivity port is a choice of design that would not meet the needs of some users, especially those who often make presentations, thus relying on multiple connectivity ports.
  • Its fan can be moderately loud to be a white noise maker, which can be annoying.

The Verdict

The ASUS ZenBook 3 UX390UA has the beautiful looks, power and the extreme portability that definitely outweigh whatever drawbacks it has. This laptop will certainly make a smart purchase especially if you are going to use it for professional purposes.
