Cheap Gaming Keyboard with Lights, but without RGB

<-----sponsored ADS----->

We met in the past with ADATA’s XPG gaming brand, but so far we have not used their gaming peripherals. The first product that comes to our editors is the Infarex K20 mechanical keyboard, a model equipped with clicky switches, colorful lights and a simple design without too many elements to stand in the way of a quality gaming experience all at one very low price. However, this description is “too good to be true”

The XPAR Infarex K20 is not a premium keyboard, so when it comes to design and construction, we did not have many claims. So, we were completely surprised when we removed the keypad from the box and found that it was not made 100% of the plastic. While the exterior construction is really “plastic”, at the bottom of the keys we have an “open” metal plate that is easier to clean in time than other “darker” models.

when we found that ADATA did not include programmable extra keys on the gaming keyboard on the side, but we were also disappointed that it was not even wanted to incorporate elements to improve the user experience. For example, many high-end keyboards come with a dedicated volume wheel and multimedia buttons. These functions are controlled using the FN key and the F1-F7 buttons at the top

With a standard design with normal size keys and keypad caps with a soft, matte texture to touch, from From a distance, it might seem like a normal office keyboard, even a trivial one we could say. As soon as it is connected to a USB port, this sensation disappears and seems to resemble a vampire or a “Christmas tree.”

XPG features this keyboard as a “colored light”, but it does not say anywhere that we are dealing with an RGB keyboard. Nor is it a keyboard with RGB illumination, but a keyboard that displays a different color of lighting for each row. The top row is red, the second is orange, then we have a yellow row, one green, one blue and a pink one. As the colors can not be changed, the keyboard benefits from 11 light animation programs, with the ability to accelerate or slow down the speed. Fortunately, there is also the option to completely stop the lights, something we encourage everyone to do in the case of K20 tasking.

An interesting element that points to details of those responsible for the design XPG products is that multiple-key keys have all the characters at the top, where they can be fully illuminated, something that does not even exist on even more expensive keyboards. Being a keyboard with illuminated switches and “open” design, wait for the light to “drain” through the keys.

Another interesting feature for this facade is the cable management channel on the back. Basically, you can draw multiple threads through that channel, or you can move the direction to get the keyboard thread. Either left or right, beside the usual position in the center. In fact, the cable is covered in fabric and seems to be durable.


The Infarex K20 is a mechanical budget, so we did not expect to receive Cherry switches on such a model. XPG chose the closest alternative, that is, buttons made by Chinese company Kailh. This is the Kailh Blue model, Cherry MX Blue Clones, which offers an unexpectedly similar experience.

The Kailh buttons appear to be a little easier to press, requiring only 50g of actuating force , as opposed to the 60g needed for the MX Blue tastes, but this also provides a slightly higher operating speed. In addition to this, the keyboard seems to be very precise in normal use and even in games.

The advantages of a keypad with mechanical switches are the sound feedback you receive at every press . This makes it easier to detect accidental pressures or easier to avoid, as each push requires more force applied to the key. In “office” use, this can help with accuracy in editing and faster identification of mistakes, while in games, every action on screen can be identified with a keystroke.

Obviously, being a keyboard with clicky switches, this is recommended for use in a more … private space, where not to disturb others. We do not recommend such a keyboard for use in an open space office or home in a common room, where other people may be disturbed by the noise of pressure

However, we can not fail to declare disappointed by the lighting system implemented by XPG. Even a single-color keyboard across the surface would have been preferred to a model in all the colors of the rainbow, but horizontally. We hope that XPG will give up these LEDs in the future and integrate either configurable RGB keys or a single-color backlit keypad (white or red appear to be the most common colors on RGB gaming keyboards). [19659004] One thing would be to object: as the light control buttons took the place of the Print Screen, Scroll Lock and Pause keys, Windows screenshots from keyboard shortcuts are impossible to do (Windows + Print Scren or Print Screen + Paste in applications), and the Scroll Lock LED is physically present on the keyboard, but it can not be lit because there is no key. Under these conditions, the LED could be omitted from the assembly.


XPG Infarex K20 from ADATA is a simple, offers a pleasant user experience when it does not have the light beacons. It benefits from mechanical budget switches, but they do their job very well, despite the stigma that many have for the Kailh buttons
