Review ASUS ROG G20AJ gaming desktop computer

    Once upon a time, the term "gaming computer" meant a desktop PC assembled from standard components, often with the best features on the market. The vast majority of such machines were assembled by the owners themselves. Later, computer sellers began to offer under the name of "gaming" the most powerful among the PCs they assemble. But these devices still lacked one important component. Users who paid very decent money for powerful computers were justifiably proud of their “pets”. And many were upset that your “iron warrior”, with whose help you enjoy high-resolution games with twisted graphics settings and high FPS, looks as ordinary and nondescript as the vast majority of computers. Someone was engaged in modding, although most put up with this. Finally,

    And here we offer a closer look at the new representative of the ASUS Republic Of Gamers line of gaming computers, the G20AJ.

    Packaging and equipment

    The computer comes in a medium-sized box with beautiful color printing. With dimensions of 19 x 59 x 40 cm, the package surprises with its noticeable weight. Inside is a system unit, very compact and weighty; dual power supply; wired keyboard and mouse, as well as two standard power cables.

    Appearance and design

    External elements of the system unit case are made of plastic. The color of the sidewalls is not perfectly black, but rather a very dark gray. The “layer” between them is painted in a beautiful red metallic. The total body volume is only 12.5 liters. The assembly is very high quality, the parts are perfectly fitted.

    The chopped, angular outlines of the hull evoke thoughts either about the cruiser of the imperial fleet, or about the latest missile destroyer of the Zumwalt class.

    The design of the system unit involves a desktop layout so that the proud owner can enjoy the sight of an aggressive and stylish case, and at the same time boast to friends and acquaintances. When you press the power button, the LED panels hidden behind the decorative grilles light up on the front panel and under the bottom. By default, red is set to match the central “layer”. But with the help of a special application it will be possible to change the color of the glow of the panels, I will mention this below.

    The power button is located on the front panel, and from a habit to notice it is not easy. Also in front are (top to bottom): an optical drive tray, two USB ports and headphone and microphone jacks.

    On the top face there is only an outlet ventilation grill. You can also see a large plate radiator under one of the plastic grilles.

    Behind traditionally is the bulk of all kinds of ports and connectors. Again, listing from top to bottom:
    • six USB ports (including two USB 3.0), a LAN port nearby,
    • six audio connectors and a Kensington lock,
    • an HDMI port,
    • video card ports and two power connectors.

    You can also put forward such a “secret” plate at the back:

    The dual power supply is a bookcase of two separate modules inserted into the mounts of thick hard rubber. The interlayer between the modules is also rubber. As you can see in the technical specifications, the power of these modules is different: 180 and 230 watts. Moreover, it will not work to mix up the connectors when connected to the system unit, they are completely different. Very effective protection against the fool.

    Such a strange, at first glance, design solution for the power supply was dictated, apparently, by the need to provide passive cooling. Probably, it was not possible to make or find a power supply unit of suitable power that did not require blowing, so I had to make such a “sandwich”. At the same time, this somewhat simplified the task of internal power distribution for a large number of motley consumers. On the other hand, users will have to hide this whole bunch of wires somewhere.

    The mouse is quite large and elongated. Light weight and a wired connection are traditionally considered a must have for hardcore gamers, especially for fans of network shooters. But the glossy surface looks very impressive only until the first touch. The mouse is instantly covered with fingerprints and specks of dust, so if you don’t give a damn about it, it’s best to immediately put a cleaning cloth next to it.

    The keyboard in the set provided for review was non-Russian. It is made of dark gray matte plastic, very rough to the touch, a rather unusual feeling.

    The key travel is large and one cannot say that it is especially comfortable, it feels like some kind of friction when pressed. At the same time, the overall height of the keyboard is very large, 25 mm.

    For those who like to play in the dark, there is a blue backlight that can be turned on and off by pressing a separate button.

    Changing the brightness is not provided. Also in the upper right corner there is a large volume control knob. In Windows 8.1, the regulator worked without problems, but in Windows 7, the system volume slider did not respond to the rotation of the handle.

    All the necessary software is installed on the computer, just connect the monitor, and you can work and play. The operating system uses 64-bit Windows 8.1. ASUS cautiously stuffed G20AJ with a large number of various applications covering the needs of 95% of users.

    Describing all installed applications will be inappropriate, and pointless. I will dwell only on a couple of the most interesting proprietary utilities from ASUS.

    ASUS Aegis

    This is an informational application for tracking all kinds of technical parameters of the system: processor and memory load, network traffic, processor temperature, fan speed. The application has a very beautiful interface in the style of science fiction films.

    ASUS Command

    This application has the richest functionality, just like a real Swiss knife. With it, you can configure and control many parameters, from hardware to software. Including change the color of the LED backlight housing. Moreover, you can change the color separately for each of the three zones: two halves of the front panel and the backlight. Plus, the brightness of each zone is also adjustable.

    Performance and work experience

    The heart of the G20AJ in this case is the Intel Core i7 4790, clocked at 3.6 GHz. The G20AJ boots up not to say that it is very fast: from pressing the power button to the full boot, 1 minute 20 seconds elapse.

    System drive performance:

    ASUS engineers have tried to make this compact gaming computer as quiet as possible. With a small load, for example, while surfing or working with documents, the system engineer does not make any sounds at all. Perhaps, in such cases, it is not the powerful discrete graphics card NVIDIA GeForce GTX 780 that is involved, but the integrated Intel HD Graphics 4600.

    The vertically oriented optical drive with a notebook-shaped tray works very quietly.

    If you put your hand to the output grilles on the roof of the case and the video card, you can feel the movement of warm air. And if it were not for the LEDs that were on, it would be possible to decide that the computer was turned off.

    With an increase in load, coolers cheerfully enter the business. When running the Unigine Heaven Benchmark puzomer with maximum settings and a resolution of 1920 x 1200, the temperature of the video card quickly crawled from 40 to 83 degrees and stabilized. At the same time, the cooling system did not work at full capacity. In general, the operating modes of coolers change very dramatically, they either start right off the bat or hit the brakes. The noise of the cooling system is quite comfortable in terms of the frequency component. This is not a high-frequency whistle of fan blades or howling motors, but a slightly lower rumble of air blown through the outlet grilles.

    The above-mentioned Unigine Heaven Benchmark showed the following results (1920 x 1200, 8x AAA, Ultra quality):

    • FPS: 50.9
    • Score: 1283
    • Min FPS: 24.4
    • Max FPS: 92.2

    Finally, I tested the G20AJ in harsh combat conditions - Battlefield 4. The game, along with four add-ons with a total “weight” of over 40 GB, was downloaded via the built-in Wi-Fi module. If this is interesting to someone, the download speed ranged from 1.4 to 2.6 Mb / s. The graphic settings were set to “ultra”, with the exception of anti-aliasing, its value was 4. During an hour of active play, I visited a variety of game zones: in the thicket of the jungle, under water, in the thick of fights. All this time, the frame rate was from 60 to 85 FPS, an average of 75. Oddly enough, this parameter fell below water most of all, it can be seen that the effects are too tricky. And not once in the whole game did the cooling system reach its maximum speed, the noise was very moderate, at the level of constant noise of the average system unit.


    G20AJ proved to be a high-performance gaming computer. At the same time, the developers managed to place it in a compact, non-standard and beautiful case with an effective and quiet cooling system. A nice bonus is the ability to adjust the color of the backlight of the system unit, so that the appearance of the G20AJ can be "customized" to a variety of tastes and interiors. Also, this computer pleased with high sound quality, juicy, voluminous, with excellent detail, which allows you to accurately determine the direction of sound sources in the game.

    Of the minuses, you can name only the mediocre keyboard in the set, and the abundance of power wires that will have to be hidden somehow.

    In general, with a light heart, I recommend this computer to all avid players. Although "ordinary" users who need high performance, for example, to work with video and graphic editors, the G20AJ will be useful.

    Recommended retail price: at the moment, the price for the configuration with the Nvidia GTX 770 2GB video card is known - 64,990 rubles.
