EVGA has announced the Z15 and Z20 gaming keyboards. Their descriptions noted using a 32-bit Arm Cortex-M33 microcontroller, which allowed to increase the polling rate to 4 kHz. The keyboards are backlit and include multimedia keys and a roller volume control. The backlighting of each key is individually configurable. Keyboards are connected to the computer via USB.

The Z15 model with mechanical switches is available in two versions. For one, the quiet Kailh Speed ​​Silver Linear switches are selected, and for the other, the tactile and audible Kailh Speed ​​Bronze Clicky switches are selected. The actuation force is 40 and 50 g, respectively. The full stroke in both cases is 3.5 mm, and the working stroke is 1.1 mm. The resource of these switches is declared equal to 70 million operations. The user can independently change the switches, customizing the keys individually to their liking. At the same time, he can also choose the third option for switches, which provides the only a tactile response.

The Z20 also comes in two flavours, but it uses Light Strike LK Optical Mechanical switches. One variant received quiet, linear Dark Gray switches, and the other received Light Gray switches with feedback. The first ones are triggered with a force of 45 g, the second ones, with 50 g. The full stroke is 3.0 and 3.5 mm, respectively, and the stroke before activation in both cases is 1.5 mm. The manufacturer estimates the resource of these switches at 100 million operations. It is also important that such a key takes less than 0.5 ms to return to its original state, while the keys on the Z15 keyboard return after being pressed in 5 ms.
