Predator 21 X

Beyond Horizons

21 inch

Curved Display

The first notebook to feature a curved display leads you to a new world. A world that bends, pulls you in and never lets go.

Eye Tracking Technology

Focus on what matters — the game. Eye tracking handles natural eye movement so you spend less time jostling analog stick and swiping mice.

Cherry MX Switches

Feel the difference with each press of the mechanical keys: imbued with Cherry MX switch technology and designed explicitly for gaming with an edge.

Light It Up

What good would a top-of-the-line keyboard be without a little RGB backlighting? With PredatorSense, you can tailor the colors to your liking.

Mechanical MX Brown

Mechanical keyboards, heralded by many as essential to gaming, are tactile, responsive and have just the right amount of push without the noise.

Flip-Over Module

Tactile numpad and precision touchpad in one flippable device with adjustable lighting through PredatorSense. No matter the situation, you’re ready.


Dual NVIDIA® GeForce® GTX 1080

While one NVIDIA® GeForce® GTX 1080 is pheonomenal, we decided on two — in SLI — because MORE. Each GPU is overclocked and eager for a challenge.


To be the best, you need the best. Unlock real potential with the overclocked 7th Gen Intel® Core i7 processor and put the 21 X to the test.

Enough Memory? Yep

This machine is absolutely filled to the brim with RAM. With 64GB of DDR4 2400, you can push multi-tasking to the limits and then some.

We’ve Been Raided!

What’s better than a PCI express SSD? Two PCIe SSDs, using NVMe technology, in RAID 0. AKA — ridiculously fast drives. Don’t blink. You’ll miss the boot up.


5-Fan Cooling System

Be one with the cold. Exquisitely designed and deadly efficient, five fans work in unison to maintain a constant cool



Ultrathin and all metal, three Predator AeroBlade fans keep your GPU/CPU at a nice, cool temp. Listen closely as they whisper, “game on, my friend. Game on.”

Heat Pipes? Nine

That’s right. Nine heat pipes distribute and rid the 21 X of its excess heat. With great power, comes great heat — comes incredible cooling.

Go With The Flow

With five fans, you better believe the aerodynamic airflow is cold and fast. Before you know it, you might just forget it’s producing heat at all.


4 Speakers + 2 Subwoofers

Surround yourself with the superior sound of Dolby Audio Premium, blaring through a four speaker/two woofer setup. Things are about to get loud.

It Just Sounds So Good

Hear more — more sounds, more clarity, more range, more EVERYTHING. A 3-way Hi-Fi design makes sure what you hear is clean, crisp and weighted with bass.

Dolby Audio Premium

Dolby Audio Premium delivers rich, powerful sounds. By dynamically adjusting the audio you’re given theater-like quality in a virtual surround sound experience.


TrueHarmony utilizes a unique design that offers more accurate sound reproduction and fuller-bodied audio.
