Build a Ziggurat / Laptops and PCs

0 847

When assembling a powerful gaming PC, money was always the biggest problem. Even before the growth of the dollar, the mention of which was already nagging, a really fast processor and a really powerful single-chip video card cost a lot, about 50 thousand rubles. And to them it is necessary to purchase a motherboard, RAM, a bunch of other iron, as well as a spacious enclosure into which all this economy should fit. There were no other problems in general.

There were no special difficulties with assembling a powerful and quiet gaming PC: it was only necessary to think carefully about the cooling system and invest more money in it. But when trying to build a powerful, quiet and at the same time compact gaming PC problems began. The vast majority of cases for such a task does not fit, and it is from them that the computer's dimensions depend.

Of course, on sale there are small cases, in which you can fit even a large video card like NVIDIA GeForce GTX 980 or AMD Radeon R9 290. But they will not really be compact, and they look like an amateur . What to do, these are the costs of the universality of all computer cases on the market.

Here the producers of all kinds of computer hardware come out onto the stage, releasing, among other things, also computers entirely. Giants like ASUS can afford to produce gaming PCs in specially designed, customized cases that can not be found in stores. The advantage of such computers will be an unusual design, compactness and, if the manufacturer especially tries, quiet and efficient operation of the cooling system. Inside such cases there will be no "extra" volume, and the cooling system can be as unique as the case itself.

This is how the gaming PC ASUS ROG G20: compact, fast and quiet. The maximum thickness of the shell is only 10 centimeters, and its appearance can be envied by almost any computer case.

# External appearance

Judging by its appearance, ASUS ROG G20 is more like a game console, a Steam Machine or a ziggurat – remember, there were such truncated pyramids in the days of the ancient Sumerians? At the same time, it contains almost the most powerful iron from the currently available one.

On the front, top and bottom panels the manufacturer has placed patterned ventilation grilles, behind which is a multicolored LED backlight. Also on the front face (or faces? – the body is made so that it seems like there are two of them) ASUS ROG G20 there is a power button, two USB 3.0 ports, a pair of 3.5 mm headphone and microphone jacks, and a thin optical Drive.

The upper panel, side view

All the other connectors are located on the back of the gaming PC: six USB ports, two of which relate to the third version, an Ethernet network connector, six audio outputs, an HDMI port, and the back of the video card on which other video outputs are located: DL DVI- D and DL DVI-I, HDMI and Display Port.

There are also two power connectors on the rear panel – the ASUS G20 requires two power supplies. One PSU is used to power the video card, and the other is used for the rest of the system.

Two blocks are combined with each other with a rubber backing. This is not an obligatory version of the layout: if necessary, the blocks can be pulled out of this rubber case.

The total power of two units is 410 watts – just right for a gaming PC with one video card and limited expansion capabilities.

In the box with a PC are a wired keyboard and mouse. This periphery is made specifically for the ASUS ROG G20, and it can not be purchased separately.

The complete mouse was the simplest manipulator with two buttons and a wheel in between. But the keyboard is more interesting: its keys have LED lighting, and above the digital unit is a round volume control.

Backlight is also in the PC itself: it has a bottom and a front face highlighted.

# Technical Specifications

There may be several modifications of the ASUS ROG G20 in retail. They will differ from each other by processors, video cards and storage capacity. In the test lab got quite powerful, though not the most productive modification of the G20.

Inside our version of the ASUS ROG G20 is a desktop quad-core Intel Core i7-4790 processor with a frequency of 3.6 GHz (up to 4.0 GHz in Turbo Boost mode), L3 cache size of 8 MB and heat pack of 84 watts. In other configurations, another quad-core processor (not supporting Hyper Threading) – Intel Core i5-4460 – can be installed in the ASUS ROG G20. Or it could be a dual-core processor (but supporting Hyper Threading) – Intel Core i3-4150.

The G20 motherboard is based on the Intel H97 chipset, its full name ASUS H97-I / G20AJ / DP_MB will not be found in the price lists of computer stores, because the board is designed specifically for this gaming PC and not sold separately.

The amount of RAM in our experimental is 16 GB in all its modifications. Two SO-DIMM DDR3L-1600 notebooks are responsible for the memory. Such a volume of RAM will be enough not only for modern games, but also for working with video and photos.

There should be no problems with the graphics of our experimental one, because it has one of the top-end video cards: NVIDIA GeForce GTX 780, and the processor video core has not been disabled by the manufacturer. As for the modifications, other NVIDIA cards can be installed in the ASUS ROG G20:

  • NVIDIA GeForce GTX980 (4GB);
  • NVIDIA GeForce GTX970 (4GB);
  • NVIDIA GeForce GTX760 (2GB);
  • NVIDIA GeForce GTX750 (1GB / 2GB);
  • NVIDIA GeForce GTX745 (1GB);
  • NVIDIA GeForce GTX780 (3GB);
  • NVIDIA GeForce GTX770 (2GB).

Support for next-generation wireless networks is another trump card under the body of our experimental. Inside this PC is the Realtek RTL8821AE module, which allows you to connect to networks of 802.11 a / b / g / n / ac standards with frequencies of 2.4 and 5 GHz.

There were two drives in such a compact computer. This SSD Kingston RBU-SC400S37128G volume of 128 GB and a usual 3.5-inch terabyte hard drive TOSHIBA DT01ACA100. It is noteworthy that a similar SSD Kingston can not be found in the price lists of domestic stores, which can not be said on the HDD – it is often found in retail. In other versions of the ASUS ROG G20, an SSD of up to 256 GB and a HDD of up to 3 TB can be installed.

ASUS ROG G20 is about like a gaming laptop, about 80 thousand rubles. This, of course, is expensive, but on the other hand the power of such a gaming PC will last for several years. True, so many are asking for the only configuration that is still on sale – all the same, but NVIDIA GeForce GTX 770 is used as the video card. It was not possible to find the tested configuration at the time of writing the article.

# The internal arrangement of the ASUS ROG G20

The slim body of the ASUS G20 contains the power of a full-fledged gaming PC, which means that the issue of assembling and cooling its iron turns out to be very interesting. According to the official website of the manufacturer, the cooling system of this gaming PC will suck the cold air through the ventilation slots on the bottom, and let out hot air through the top panel. Also, there is a duct for the video card.

Now is the time to open the case and see how our subject looks from the inside. Initially, the process of opening the ASUS ROG G20 was very simple. To disassemble the computer, remove the top decorative panel and unscrew the two screws: on the upper and lower ends. After that, you can gently move aside the left side panel of the gaming PC.

On the inside of the side panel there are three holes that resemble the face of an angry Martian, but in fact they are used for cooling systems of a video card and processor. Through these holes, cold air enters their coolers.

The inside of the ASUS G20 is extremely compact. After the first (and simplest) phase of disassembling the PC, it becomes clear that ASUS engineers tried to use the internal space of the shell as efficiently as possible. Each cubic centimeter of volume is occupied by some important piece of iron.

The processor cooler is made very simply. Two heat pipes with a diameter of 8.5 mm are fed to a radiator, which is cooled by means of two large turbines.

Immediately I want to note the first minus the compactness of the ROG G20: the heat pipes pass exactly above the RAM. She, like any other element of the PC, unnecessary heating is absolutely not needed.

The video card in the ASUS G20 was an ordinary, reference model. There are no frills in its cooling system – exactly the same video adapter can be found in retail without problems, except that it will not be easy to meet the L-shaped PCIe adapter in Russian stores.

After dismantling the video card and the turbines that cool the processor heatsink, you can properly consider the ASUS ROG G20 motherboard. "Motherboard" of this gaming PC does not belong to any standard form factor because of its unusual shape. All important electronics are concentrated on the top half of the motherboard, and on the lower half is the power subsystem of the video card, drives and the case lighting.

The hard disk, located next to the video card, causes some concerns. The fact is that the external side of the video card, looking directly at it, under the most unfavorable conditions can heat up to 80 or 90 ° C. In this scenario, the video card will heat the hard disk, and its maximum operating temperature, according to the specifications, is 60 ° C. About how much the hard disk will actually heat up with the maximum load on the PC, we will tell you in the next section.

Unfortunately, it was not possible to disassemble the last cog in the ASUS ROG G20. The fact is that the processor heatsink closes two screws that press the heat distribution cover of the cooling system to the processor. Therefore, there is a fair question: how did the manufacturer able to screw the cooling system to the processor socket, if the radiator closes two of the four screws? He can have several answers, and the search for the most probable of them can be done in the comments. And we will collect everything back and proceed to testing.
