Design and Build Quality

The chassis of the Asus Tuf Gaming A15 FA566IU-HN254T has a plastic chassis with a smooth grey finish. The design here is a lot better than other Asus Tuf variants but still has a lot of scope for improvement. The build quality here is solid however the lid wobbles a little. The display maintains a modern design with thin 7mm bezels.  According to Asus, the Asus Tuf Gaming A15 FA566IU-HN254T goes through rigorous MIL-STD-810H tests. These tests include Drop, Shake, Humidity, Heat, and Cold.

Keyboard and Trackpad

The Asus TUF Gaming A15 FA566IU-HN254T has a chicklet style backlit keyboard. The WASD keys are transparent and get a little extra RGB backlight. The arrow keys are a bit small with the num pad being a little narrow. Overall you will have a good experience while typing and Gaming. The trackpad on the other hand has a smooth matte surface though it lacks a little precision. The dedicated mouse buttons on the bottom quite clicky and tactile and it is always better to have dedicated buttons.


The Ports selection here is quite basic and has nothing special going for it but at the same time, it has all the essential ports that 95 percent of people need.

  • 1 x 3.5mm COMBO audio jack
  • 1x Type-A USB2.0

  • 1x Type-C USB 3.2 (Gen 2) with display support DP1.4

The GPU here is an upper midrange GTX 1660Ti with  GB of dedicated graphics memory though it is true that you may not be as powerful as its 20 series RTX counterparts however I don’t think so there is any game that would be unplayable.
