    Deceptively Powerful

    ROG G20 is designed to dominate the small form factor gaming desktop segment, and has already received critical acclaim, receiving the Best Choice of the Year and Golden Awards at Computex 2014. G20 features a compact 12.5-liter case that houses a 4th gen Intel® Core™ i7 processor and NVIDIA® GeForce® graphics to give you unstoppable performance for games and home entertainment in WQHD quality.

    In spite of this performance, G20 delivers incredible energy efficiency. It draws just 20W in Eco Energy mode to give you 50% more energy savings than the industry average1. There's even the ASUS-exclusive Aegis application to help you monitor system parameters.

    G20 is designed with no visible exterior side exhaust vents. G20 has a thermal design that takes advantage of natural convection, with a hidden airflow channel that ensures efficient heat management for marathon gaming sessions. On top of that, it runs silently at just 22dB at idle2.

    On the outside, G20 sports a bold design – boasting a matte-black finish, aggressive lines, Mayan-inspired markings and customizable lighting effects showcase up to 8 million colors.

    A one-stop gaming and entertainment system, ROG G20 is set to dominate the small form factor gaming desktop segment. Despite its 12.5-liter size, G20 packs quite a punch, giving you the performance you'd expect from a hardcore gaming system at a fraction of the size.

    Under the hood, ROG G20 can be specced with up to a 4th gen Intel Core i7 processor to give you unprecedented levels of gaming and multitasking performance. G20 gives you the power to take on the most demanding of tasks, allowing you to play games at their highest settings, watch videos in 4K UHD and even create awesome websites and 3D models for work.

    flexibility to choose the ROG G20 that best
    suits your game, from GPU options to
    hybrid drives that deliver the speed of an
    SSD with the capacity of a platter drive.

Through a unique mix of hardware and audio tuning software, SonicMaster brings you right into the fight. Gunshots ring out, explosions reverberate and even footsteps become auditory cues on the digital battlefield. Be immersed in battle whether you're using a headset or speakers3. ROG AudioWizard sound processing provides ROG Desktops with an additional layer of audio enhancement, with up to five customizable modes you can easily switch on-the-fly.

    Intel® Gigabit Ethernet with GameFirst II
    Less lag for more wins!

    The very latest Intel® Gigabit Ethernet both lowers demands on the processor and improves connection stability — a double win for online gaming. Adding more lag-reducing support is ROG's GameFirst II with cFosSpeed traffic-shaping technology. Revamped to display an even more intuitive user interface, GameFirst II exclusive's EZ Mode open allows beginners to lower lag with no expert knowledge; while Advanced Mode allows hardcore tweakers to take full control. Either way, ROG G20 offers latency that's up to eight times lower than standard Ethernet, even when handling heavy network traffic — so your games and victories come first!

    Effective Heat Management for Ultimate Stability

    ROG G20 is designed with no visible exterior side exhaust vents in order to keep the chassis' neat, clean lines. ROG G20 has a thermal design that takes advantage of natural convection, with a hidden airflow channel that ensures efficient heat management. Two internal fans further enhance heat dissipation, making ROG G20 ideal for marathon gaming sessions.

    Efficient and Quiet

    G20 isn't just powerful, it's energy-efficient as well. In Eco Energy Mode, its ultra-low power design draws as little as 20W at idle - so you won't be racking up huge electricity bills when you leave G20 on overnight to download games. It can also function as your home server with Intel® Ready Mode technology, drawing only 10W even when it's connected to the internet – as much electricity as a low-power light bulb. On top of that, it runs whisper-quiet at just 22dB at idle.
