The ASUS TUF Gaming K3 is a full-size mechanical keyboard with 104 keys and it is really TUF (tough) with 1.1kg weight and almost no flex on its structure.

The TUF Gaming K3 has a floating key design, with an aggressive branding on the upper right corner of the keyboard. It is very easy to clean this type of keyboard, you just need to brush off the dust on the top plate.

As for the layout, it has a standard layout with 104 keys so changing the keycaps will not be a problem.

For the connectivity of the keyboard, it has a thick non-braided, non-removable cable with USB passthrough that allows you to insert a low-powered USB device thru it. With this, it is somewhat hard to bring this keyboard around with its hard and not so flexible cable.

At the back of the keyboard, you will notice the design of the TUF series with a pixelated camo and rugged military design to showcase how tough the keyboard is and will withstand during long gaming sessions. In addition, you can see 2 Flipout feet with rubbers on it and 2 large rubber pads on the bottom to keep the keyboard in place.



When it comes to switches, ASUS decided not to use Cherry for this one due to the fact that Cherry switches are expensive and are usually used for the ROG mechanical keyboards. Obviously, they will need to source out a cheaper mechanical switch which is Kailh. During the past few years, Kailh was regarded as one of those clones that have a higher rate of chattering compared to other or similar clones like the Gateron. On the other hand, the Kailh used in this board has the newer mould already and thus making it a good substitute for Cherry MX to keep its price lower.


ASUS used a plate mounted OEM stabs and it’s unlubed, expect a lot of rattles here. On the contrary, you can safely use any dielectric grease to lessen the rattle without voiding the product’s warranty.



The material used here is ABS. ABS (short for “ Acrylonitrile Butadiene Styrene ”) is a commonly used plastic and shines easily.


The keycaps are coated and the legends are UV printed, it will be easily fade over time. Fonts are decent but with a little bit of gamer-y style.


The ASUS TUF Gaming K3 has an OEM profile keycaps. Mainstream brands/keyboards are usually using this kind of profile since it is widely available from the manufacturers.


The ROG Armoury Crate is now the latest software for all ASUS products including the TUF series. On the upper left part, you can see the icon with keyboard and mouse, meaning you can sync other ASUS products like the Impact 2 Wireless with other products with the ASUS Aura Sync. In addition to this, the TUF Gaming K3 has only 2 tabs in which you can change the key assignment in the first tab. Secondly, you can adjust the lighting modes on the second tab with 10 different lighting effects + the Aura Sync function.

The TUF Gaming K3 doesn’t have any macro functions in this software, only via OTF macro recording which is not user friendly for some gamers who need macro functions. On the positive side, it has an onboard memory which saves all of your settings if you need to bring this with you when you travel.


The ASUS TUF Gaming K3 is retailed at around 4,000 pesos, making it affordable for most ASUS users/fans to have a mechanical keyboard that has an Aura Sync compatibility with their other ASUS components. The overall quality of the TUF gaming k3 is decent, solid with no flex on both sides. In addition, it has RGB lightings and equipped with the newer version of Kailh switches. You can either pick a red switch variant if you mostly play FPS games, browns for balanced typing and gaming and blues if you like that clicky sounds when typing. Moreover, it has an included magnetic wrist rest with adds comfort for those long periods of typing and gaming.

There are a few things to take note of when you have decided to get one. First, it has no macro functions that you can adjust on its software, only via on-the-fly. Second, it has a non-removable cable so you can use a custom cable. Lastly, installing the ROG Armoury crate forces you to update the firmware of the keyboard for you to be able to use the application.
