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 hull heavier with the help of bolts set on tape. Now nobody is engaged in such "life hacks", and there is no need for it. For a long time, the weight of the power supply does not say 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, this is where the cables come loose!»In fact, only the name of the manufacturer, the price and the efficiency classification of 80 PLUS speaks about the reliability of the unit.
All three points, as you yourself understand, are interrelated. So, cheap devices from SeaSonic, ENERMAX and be quiet! on sale you will not find. Yes, the computer power supply market is quite conservative. Therefore, the name plays an important role. The paradox is that there are not very many manufacturers of power supplies themselves, and companies that produce ready-made solutions under their own logo are a dime a dozen. It all depends on the office itself, namely on how closely it monitors the production process. Therefore, sometimes there are sad situations when at first the quality of a particular model is kept at a consistently high level. And she is gaining well-deserved popularity. But a year or two later, under the same name, they release a block on a different platform with a modified "filling" of inferior 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 over. But, as Ostap Bender said, abroad will help us!
This unit (like the 850-watt model of this series) is based on the Enhance development platform, has quite decent electrical output parameters, high-quality elements (in particular, purely Japanese capacitors) and a partially modular design with flat cables. PCI-E 6 + 2-pin connectors available 6 pieces.
The Chieftec GPS-1000C power supply unit also has approximately equal price, electrical and acoustic characteristics.
The advantages of this model can be written down to the shorter body length (160 mm versus 180 mm), but the disadvantages, in our opinion, are more serious than that of the Volga: less convenient cable system (more non-removable cables, fewer available SATA and Molex connectors) and a significantly shorter warranty period.
Among the more efficient models, the Zalman Acrux series power supplies are 80 PLUS Platinum certified as the most affordable PSUs at 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 new products.
When choosing components for a new computer, it is very important to choose the right power supply unit (PSU), since insufficient power will lead to unstable operation of the PC. On the other hand, buying a power supply unit with a large margin is also not a good idea, as this will hit the budget hard and will not allow you to assemble an optimal configuration. In this article, we will tell you what kind of power supply is needed for NVIDIA GEFORCE GTX 1060, 1070, 1070 Ti, 1080 and 1080 Ti video cards.
Power supply for GEFORCE GTX 1060
In order to determine what kind of power supply is needed for the NVIDIA GEFORCE GTX 1060 video card, first of all, let's turn to the characteristics on the manufacturer's official website. According to official data this video card consumes 120W electricity. At the same time, this indicator is the same both for 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 power supply is needed for the operation of such a PC. In this case, we will use. If you choose an Intel Core i9 9900KF processor, one GEFORCE GTX 1060 graphics card, 2 hard drives, 4 RAM modules, 4 fans, 4 additional PCI express cards and 1 DVD drive, then MSI calculator recommends 400W.
Considering the above data from NVIDIA and MSI, we can conclude that For normal operation of the NVIDIA GEFORCE GTX 1060 video card, a 400 W power supply is required... If you want to play it safe or have a stock for upgrading components in the future, then you can purchase a power supply unit with some margin. For example, you can take a model that delivers 100 watts more. Thus, for GTX 1060, the power supply will be 500 W with a margin.
PSU 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 graphics cards, we need to study the characteristics on the NVIDIA website. According to the official specifications, this video card consumes 150-180 W power. Moreover, this indicator is the same for both the regular version and the improved version with the Ti prefix.
Also, in the characteristics of the video card, NVIDIA provides recommendations on the power of the power supply. In this case, for both versions of the GTX 1070 recommended power supply unit is 500 W.
You can check the recommended power supply power, which NVIDIA indicated, using the online power supply 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 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 such components MSI calculator recommends a little over 450W.
In this case, the MSI calculator produced 50W less than NVIDIA recommends. Therefore, for maximum reliability, you need to focus on a higher value.
Thus, we can conclude that for normal operation of the NVIDIA GEFORCE GTX 1070 or 1070 Ti video card, a 500 W power supply is required... If you want to leave room for an upgrade or just want to play it safe, then you can install the PSU with some margin. For example, you can purchase a model that will deliver 100 watts more. Thus, for GTX 1070 and GTX 1070 Ti, the power supply unit with a margin will be 600 W.
PSU 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 is 250 watts.
Also in the official specifications, the company indicates the recommended power supply capacity. In this case for a GTX 1080 graphics card, the recommended power was 500 W, and for the GTX 1080 Ti video card - 600 watts.
You can check the power supply power, which is indicated in the characteristics, using the online power supply calculator. Such calculators allow you to make an approximate estimate of the power supply capacity based on the specified components. For verification, we will use.
First, let's check the values for the GEFORCE GTX 1080. Let's point to the 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 slightly more than 450 W(same as 1070 and 1070 ti).
To check the GEFORCE value of the GTX 1080 Ti, we will use the same components. GTX 1080 Ti result - 525 W.
In the case of GTX 1080 and GTX 1080 Ti graphics cards, MSI calculator gives values that are noticeably lower than those recommended by NVIDIA. Therefore, when choosing a power supply unit, you should first of all be guided by the official values from NVIDIA.
From this we can conclude that GTX 1080 requires 500W PSU and for the GTX 1080 Ti at 600 watts. If you want to play it safe or leave some margin for future upgrades, then you can take a model with 100 watts more. Thus power supply with a margin for the GTX 1080 will be 600 watts, and for the GTX 1080 Ti - 700 watts.
With the release of the first Maxwells, the appetites of NVIDIA video cards were tempered; this trend was continued by the Pascal architecture. The early adopters GTX 1070 and GTX 1080 draw 150W at maximum load. And if you do not plan on SLI, then it is quite possible to save on the purchase of a power supply unit, and the freed up funds can be more effectively used to purchase memory sticks or large-capacity SSDs. Moreover, even among the models with low power there are "gold nuggets", such as the updated AeroCool VP-450 with 80 Plus Bronze certification.
We have already tested the power supply from this series - AeroCool VP-650. The whole series has improved in terms of power and efficiency. All this was carried out while maintaining the cost, but you need to be careful: versions of the previous generation may remain in stores, they do not differ in name and labeling. The main and obvious difference is the appearance of the 80 Plus Bronze mark on the box. At the time of publication, its average cost, according to the Yandex.Market service, is 2,700 rubles.
