Power supply for 2 cards 1080. How to choose a power supply
In early 2017, Nvidia introduced a new top-of-the-line consumer video card line based on the Pascal architecture. She became Nvidia GeForce GTX 1080 Ti. The video adapter is designed for users who do not have budget restrictions. Users are used to the TITAN line bringing increased performance, but in this case, the novelty blurs the line between the popular series and the ultimate TITAN X models.
Like , the GTX 1080 Ti is based on GPU GP102. Because of this, their characteristics are similar, but the memory capacity of the novelty is reduced from 12 to 11 GB. The reason for this lies in the reduced memory bus of 352 bits instead of 384. The small difference in the amount of video memory is compensated by its increased frequency.
Main geforce specs GTX 1080 Ti are presented in the table below.

The impressive characteristics of the new video adapter significantly affect its price. Immediately after the release, the price was about $ 800. But due to a significant increase in the popularity of cryptocurrency and the profitability of its mining, the demand for a video adapter has grown significantly. Accordingly, the price too. Now you can buy it for about 1100 dollars.
GTX 1080 Ti review
Appearance reference video card is practically no different from other models in the line. The developer corrects the internal content, and the outer shell undergoes only minor cosmetic changes. It is worth noting that the look of the reference model is liked by most buyers. The case made of aluminum with chopped edges is already considered a classic for Nvidia.
The video adapter supports SLI. A new SLI bridge was developed for this line, which increased the throughput. Given the optimization, the optimal number of video cards is limited to two, but in theory four can be used.
Without load, the temperature does not exceed 45 degrees. Graphics card operating temperature Nvidia GTX 1080 Ti in games is about 65-70 degrees. Fan speed does not exceed 1500 rpm.
As the testing and review of the Nvidia GTX 1080 Ti video card showed, the noise level is very insignificant when working with a load. If you use a video adapter for cryptocurrency mining, then during prolonged operation at maximum power, it may overheat. In this case, it is recommended to purchase water cooling for the GTX 1080 Ti graphics card.
What power supply is needed for the GTX 1080 Ti
The power consumption of the GTX 1080 Ti is 250W, which is 70W higher than the previous model. The graphics card uses a seven-phase power system, which has dual switches to reduce the load. For the reference model, the manufacturer recommends using a power supply with a power of at least 600 watts.
What processor is needed for the GTX 1080 Ti
To unleash the full potential of the video card, you must use the processor Intel Core i5 with a frequency of 4.5 GHz or Intel Core i5 with a frequency of 4 GHz. Play with less powerful processor uncomfortable. The CPU simply does not keep up with the video adapter and the textures are loaded at the wrong time. Also, in some games, twitching of the picture may be observed.

Quality is the main characteristic of any power supply. In the dashing 90s, a good breadwinner of all components was judged by its weight, but the cunning Chinese quickly learned to make the hulls heavier with the help of bolts mounted on adhesive tape. Now no one is engaged in such "life hacks", and there is no need for this. For a long time, the weight of the power supply does not mean anything. In 2016, it is very difficult to determine the build quality by external signs. " metal box». « With fan». « With a bunch of braided wires». « Oh, and here the cables come unfastened!» In fact, only the name of the manufacturer, price and efficiency classification 80 PLUS speak about the reliability of the unit.
All three points, as you understand, are interconnected. So, cheap devices from SeaSonic, ENERMAX and be quiet! you won't find it for sale. Yes, the market for computer power supplies is quite conservative. Therefore, the name plays a big role. The paradox lies in the fact that there are not very many power supply manufacturers themselves, and there are a dime a dozen companies that produce ready-made solutions under their own logo. It all depends on the office itself, namely on how closely it monitors the production process. Therefore, sad situations sometimes happen when at first the quality specific model keeps stable high level. And she gains well-deserved popularity. But after a year or two, under the same name, they release a block on a different platform with a modified “stuffing” the worst quality. Below is a table of reliable manufacturers, it includes those who are more or less represented in Russian retail. It is difficult to sell expensive blocks worth 10-30,000 rubles in times of crisis. Therefore, retail is mostly filled with simpler solutions. The same ENERMAX in Russia is almost “ended”. But, as Ostap Bender said, foreign countries will help us!

When selecting components for a new computer, it is very important to choose the right power supply (PSU), since insufficient power will lead to unstable PC operation. On the other hand, buying a PSU with a large margin is also not best idea, as this will hit the budget hard and will not allow you to assemble the optimal configuration. In this article we will tell you which power supply is needed for NVIDIA graphics cards GEFORCE GTX 1060, 1070, 1070 Ti, 1080 and 1080 Ti.
Power supply for GEFORCE GTX 1060
In order to determine which power supply is needed for the NVIDIA GEFORCE GTX 1060 video card, first of all, let's turn to the specifications on the manufacturer's official website. According to official data this graphics card consumes 120W electricity. At the same time, this indicator is the same for both the version with 3 GB of video memory and for the version with 6 GB of video memory.
You can check the power supply capacity recommended by NVIDIA using the online PSU calculator. Such calculators allow you to select the components used in the computer and roughly estimate which PSU is needed to operate such a PC. In this case, we will use . If choose Intel processor Core i9 9900KF, one GEFORCE graphics card GTX 1060, 2 hard drives, 4 modules random access memory, 4 fans, 4 additional cards PCI express and 1 DVD drive, then MSI calculator recommends 400W.
Given the above data from NVIDIA and MSI, we can conclude that NVIDIA GEFORCE GTX 1060 requires a 400W PSU to run properly. If you want to play it safe or have a margin for upgrading components in the future, then you can purchase a PSU with some margin. For example, you can take a model that provides 100 watts more. In this way, for the GTX 1060, the power supply with a margin will be 500 watts.
Power supply for GEFORCE GTX 1070 and GTX 1070 Ti
In order to find out which power supply is suitable for the NVIDIA GEFORCE GTX 1070 and GTX 1070 Ti video cards, we need to study the specifications on the NVIDIA website. According to official specifications, this video card consumes 150-180 watts power. Moreover, this indicator is the same for both the regular version and the improved version with the prefix Ti.
Also in the characteristics of the video card, NVIDIA gives recommendations on the power of the power supply. In this case, for both versions of the GTX 1070 recommended PSU power is 500W.
You can check the recommended power supply capacity indicated by NVIDIA using the online PSU calculator. These calculators allow you to roughly estimate the power of the power supply based on the components used. In our case, we will use . We will list an Intel Core i9 9900KF processor, one GEFORCE GTX 1070 Ti graphics card, 2 hard drives, 4 RAM modules, 4 fans, 4 additional PCI express cards, and 1 DVD drive. With these accessories MSI's calculator recommends just over 450W.
In this case, MSI's calculator produced a result 50 W less than NVIDIA recommends. Therefore, for maximum reliability, you need to focus on a larger value.
Thus, it can be concluded that NVIDIA GEFORCE GTX 1070 or 1070 Ti requires a 500W PSU to run properly. If you want to leave room for an upgrade or just want to play it safe, then you can install the PSU with some headroom. For example, you can purchase a model that will give out 100 watts more. In this way, for the GTX 1070 and GTX 1070 Ti, the PSU power will be 600 W with a margin.
Power supply for GEFORCE GTX 1080 and GTX 1080 Ti
In order to decide which PSU is suitable for NVIDIA GEFORCE GTX 1080 and GTX 1080 Ti video cards, we need to study the official specifications on the NVIDIA website. According to official information, the video card GTX 1080 draws 180W, and the GTX 1080 Ti graphics card is 250W.
also in official specifications the company indicates the recommended power supply capacity. In this case for the GTX 1080, the recommended power was 500 W, and for the GTX 1080 Ti graphics card - 600 W.
You can check the power of the power supply, which is indicated in the specifications, using the online PSU calculator. Such calculators allow you to make an approximate estimate of the power of the power supply based on the specified components. For verification, we will use .
First, let's check the values for the GEFORCE GTX 1080. Let's specify an Intel Core i9 9900KF, one GEFORCE GTX 1080 graphics card, 2 hard drives, 4 RAM modules, 4 fans, 4 additional PCI express cards and 1 DVD drive. The result of a calculator with such components a little over 450 watts(same as 1070 and 1070 ti).
To check the GEFORCE GTX 1080 Ti value, we will use the same components. GTX 1080 Ti result - 525W.
In the case of the GTX 1080 and GTX 1080 Ti graphics cards, MSI's calculator gives values that are noticeably lower than those recommended by NVIDIA. Therefore, when choosing a PSU, you should first of all focus on the official values \u200b\u200bfrom NVIDIA.
From this it can be concluded that GTX 1080 requires a 500W PSU, and for the GTX 1080 Ti at 600 watts. If you want to play it safe or leave a margin for a future upgrade, then you can take a 100 W model more. In this way power supply with a margin for the GTX 1080 will be 600 watts, and for the GTX 1080 Ti - 700 watts.
This unit (like the 850-watt model of this series) is based on the Enhance development platform, has quite decent electrical output, quality components (in particular, pure Japanese capacitors) and a semi-modular design with flat cables. There are 6 PCI-E 6+2-pin connectors available.
The Chieftec GPS-1000C power supply has approximately equal price, electrical and acoustic characteristics.
The advantages of this model include a shorter body length (160 mm versus 180 mm), but the disadvantages, in our opinion, are more serious than those of the Volga: a less convenient cable system ( more fixed cables, fewer available SATA and Molex connectors) and a much shorter warranty period.
Among the more efficient models, the Zalman Acrux series power supplies, certified at an efficiency level of 80 PLUS Platinum, can be noted as the most affordable PSUs with this level of efficiency.
Nevertheless, the appearance of interesting new products with a good combination of price, efficiency and comfort is by no means excluded. And we, of course, will try to acquaint you with such novelties.
