Asus Zenbook 3 UX390UA-RH71-CB Review

Asus Zenbook 3 UX390UA-RH71-CB Review

The all new Asus Zenbook 3 UX390UA-RH71-CB is big on power but unlike many high end models with impressive hardware is not big on size as it comes in a very compact 12.5 inch display design.

The market is crowded with plenty of budget friendly mobile options that lack any serious performance but this Zenbook is on the complete opposite with both top end performance and what you would expect to come with it, a high price tag.

Below we are going to look into this model a bit closer and list some of the biggest benefits and downsides it has to offer.


Processor: Intel Core i7-7500U

Memory: 8 GB of RAM

Storage: 512 GB SSD

Screen: 12.5 Inch

OS: Windows 10

Asus Zenbook 3 UX390UA-RH71-CB Review



There is no question that if you are looking for something extremely portable that the Asus Zenbook 3 UX390UA-RH71-CB has you covered as plenty of hard work went into designing a laptop that is road ready.

With a total weight of just 2.1 Kg and a thickness of just 1.27 cm this model from Asus is very convenient to carry around for extended periods of time.

Many consumers get the idea that if it is compact and mobile it must be lacking in power and unfortunately for many of the models on the market this is the case but not so with the Zenbook.

Asus has done a great job of cramming plenty of high end hardware into its smaller frame and the Intel Core i7 provides top end performance to easily handle everything from basic day to day use to gaming and everything in between.

Another way that they have been able to squeeze a bit more performance out of this model is by going with an SSD drive over SATA.

One of the downsides of many SSD models is the lack of storage space but by going with the larger 500 GB option this isn’t so much of a problem on this particular model and gives you a great balance of increased performance without losing too much on the storage side.

While the Asus Zenbook 3 UX390UA-RH71-CB does have plenty of great features such as the Intel Core i7 it really feels like you are paying a premium for the smaller design as this model will not be easy on your wallet.

For consumers who can live with a slightly bulkier laptop model you will be able to find other options that have equal hardware for a much lower price.

The 8 GB of memory works well, especially when paired with a powerful Intel Core i7 processor but for the price tag it feels like this should have been increased to something more like 12 or 16.


The Asus Zenbook 3 UX390UA-RH71-CB is a very interesting addition to the laptop lineup this winter and will be a very attractive option for those who have a large budget to spend on their next tech device.
