ASUS ROG GT51CA – Full Specifications and Review


The flagship of the entire Republic of Gamers line is ASUS ROG GT51CA – a gaming system unit with two NVidia GeForce Titan X graphics cards, very high performance and a few interesting features.


Appearance and equipment

The system unit comes in a very large box. It does not fit in any trunk and barely fits into the opening of the rear door of the car.

Included are a wired keyboard and mouse. These are simple models, from the frills only the volume control. The keyboard is not a notebook type, the keys are full-sized, with a large stroke.

One of the highlights of the ASUS ROG GT51CA is a special bracelet. It is made of soft material – either silicone or elastomer – and if you bring it to the system unit, you will have access to the secret section on the disk, where you can store your passwords and other important information.

The system unit is much larger than the average tower. The design is aggressive, a kind of transformer style. Steel case, with a high-quality coating, smooth plastic overlay panels.

At first it seemed to me that the front panel is a door, but it’s just a decorative element. The NFC receiver for working with the bracelet is located approximately in the middle between the logo and the top edge of the panel. This place is indicated by a small N icon.

Supply fan and cooling system

Supply fan of the cooling system immediately attracts attention. The color of its backlight can be changed using a proprietary application.

During acceleration, the backlight pulsates, the duration of this effect can be set independently. The color of the vertical front panels and the backlight of the motherboard are also separately regulated.

To the right of the front panel is a vertically located DVD drive. And on the left is the acceleration enable button.



Above is a series of connectors with illuminated designations. A very correct decision, you don’t have to peer or highlight where to stick a USB flash drive. The connectors are tilted at about 45 degrees, so they are much more convenient to use when the system unit is under the table.

On the upper plane of the casing there is a large air inlet vent closed by a fanciful grill. The top panel itself is raised a few centimeters above the wall of the steel casing, which can be seen through the grill.

Transparent window of the ASUS ROG GT51CA

A transparent window is embedded in the left wall of the case, through which you can enjoy the backlight of the motherboard and the luminous inscriptions on the video cards. You can see the water block on the processor, connected to an exhaust fan, which plays a key role in the removal of hot air from the housing.

  • The right wall of the housing is “deaf”.
  • The power supply is located at the bottom of the system unit.
  • There are several supply channels: a fan on the front panel, as well as grilles on the top and bottom of the case.
  • It’s very interesting to see how the ASUS ROG GT51CA is organized internally.
  • Behind the plastic panel in the lower right corner is a supply fan. The panel, obviously, plays the role of the duct.
  • Lattice, which was visible through the glass of the body wall:

The abundance of powerful overclocked components requires good cooling. For example, the use of CBO helps not only more efficiently cool the processor, but also does not clutter up the space above the motherboard and does not impede air flow.

  • All wires through the technological holes are removed for the blank panel on the right side of the case
  • Inside view of the upper supply grille
  • Despite two powerful graphics cards, the ASUS ROG GT51CA works great on a 700-watt power supply. A good example of monster redundancy of 1000-1500 watts.
  • Video cards are protected by steel “chippers”, which play a decorative role – they hide the ends of the video cards. Through the slits in them, the glowing inscriptions of the GEFORCE GTX are clearly visible.
  • One of the two NVMe SSDs
  • Second is hidden under the top video card, parallel to the motherboard, it is almost invisible.
  • 2 TB Winchester


Sound of the ASUS ROG GT51CA

Hardcore gamers need quality sound like air. In order to hear by ear to determine where a rocket, shell or arrow flew into you.

Not to mention the fact that you need to listen to your favorite music with good recordings and good equipment.

For the first ASUS is not responsible, but as for the equipment, the ASUS ROG GT51CA uses a digital-to-analog converter and an ESS Saber headphone amplifier.

I listened to FLAC videos from my collection, and I must say that some songs sounded for me in a new way. I even thought about replacing the audio card.

In games, the ASUS ROG GT51CA sounds great: no noise, clear detail, good spatial positioning of sound sources, impressive bass and unpressed mid and high frequencies.

Software of the ASUS ROG GT51CA

The system unit comes with Windows 10 Home installed, fully configured and ready to use, just connect the monitor and keyboard with the mouse. It turned out to be a little adware and trial software, fewer have to clean it up. Aegis II proprietary application allows you to:

  • Allocate more resources to specific applications.
  • Perform thin overclocking of the system.
  • Drive the included bracelet. To take advantage of all the amenities of this accessory, you will first need to create an account or log in under the existing one. After that, if you attach the bracelet to the case, a secret virtual disk is automatically opened.
  • Aegis II also allows you to instantly disperse the system without rebooting – just click on the inconspicuous Turbo 2 inscription in the upper right corner.


Performance and work experience of the ASUS ROG GT51CA

In terms of hardware in the ASUS ROG GT51CA, everything is very serious, top-end equipment. The processor is the sixth generation Intel Core i7 6700K.

According to the specification, its maximum operating frequency is 4.2 GHz. In ASUS ROG GT51CA the upper limit is raised to 4.3 GHz, and with one click of the mouse you can accelerate to 4.6 GHz.

ASUS claims that each processor for the ASUS ROG GT51CA is tested in overclocking for 40 hours. The motherboard is based on the Intel Z170 chipset. The amount of RAM is 64 GB DDR4 (four modules of 16 GB).


Features of the ASUS ROG GT51CA

It was very interesting to see how many FPS the system unit will show in a fairly loaded game. I tested it in Battlefield 4, including on one of the heaviest maps – Operation Firestorm 2014.

It’s not heavy in terms of the game, but in terms of the load on the video card with the Ultra settings and a resolution of 1920 x 1200, the ASUS ROG GT51CA showed 105 to 200 frames / sec., on other cards – from 140 to 200.

Probably 200 is a limitation of the engine. At the same time, the system unit did not howl with all the fans, but rather hummed quietly, with a clear rustle of flow from the CBO fan.

The main channel for the output of hot air is the fan of the CPU cooler. CPU has to puff out for everyone: CPU often goes to higher speeds, and the air flow from him is felt at a distance of more than a meter.

Warm air also exits through the power supply and slots near the graphics cards, but these channels play a secondary role.

So we can’t say that the system unit works quietly under load. If the room has a sufficiently high temperature, that is, when the summer is hot, then with active downloading or surfing, the fan periodically “gives a voice”.

Although the sound of the cooling system cannot be called unpleasant, it is mainly mid and low frequencies, pronounced aerodynamic noise when the stream passes through the CBO radiator and fan grilles.


Final Words

ASUS ROG GT51CA is a massive and very high-performance computer. Today it’s hard to put together something more powerful.

RAID0 from two NVMe SSDs is twice as fast as single drives and 6 times faster than regular SSDs connected via SATA.

64 GB of RAM is enough for any game for several years ahead. The processor will also be relevant for a long time, given the slowdown in development of new chips.

The only question is video cards: with the release of the NVidia GeForce GTX 1070 and 1080, the Titan X installed here are no longer top-end.

The fact is that the GTX 1080 was announced only in early June, and the tested sample was assembled earlier.

And ASUS already has plans to release a version of the GT51 with GTX 1070 and 1080. But in any case, buyers of the ASUS ROG GT51CA will not be left out – a pair of Titan X will plug the vast majority of existing systems for a long time.

As for the design, the system unit certainly does not look dull. Four separately adjustable backlight zones allow you to color the computer for every taste, mood, and even for a specific game. Thanks to a customizable backlight, it fits into any interior.
