Most modern users who build their own computers are focused only on processors, video cards, and motherboards. Only then does the RAM and the housing, the cooling system get a little love and warmth, but it is normal to supply power for a change. Of course, I'm not saying that everyone does exactly this, but in most YouTube assemblies, articles from the Internet or advice from close friends, this is exactly the series it sounds.
Why is the power supply the last thing we see? It is simple - it does not affect the performance of your computer. Players are always trying to get more FPS in their favorite games, investing the entire budget in three major components and buying the rest with money. Video designers and workers put resources into RAM, a multi-core processor. The PSU is not interesting to anyone, it just "starts the computer".
However, it is the "engine" of your computer. If you choose the wrong power, then most of the money invested in the purchase will be idle, or you will buy a 500 W power supply, and then the video card will become more powerful and the energy will be gone. The system has unstable operation, crashes, components overheating, blue screen of death. We will learn all this today. I must say immediately that this applies to the power supply. No matter which brand is cooler, neither light color-design nor cooling, there will be no dispute over "modular system or not". We are talking about the power and steps that you will have to take to complete it.
From Power Characteristics to Real Power
It should be immediately understood that the watts indicated in the characteristics are always different from the actual indicators. Absolutely always The only question is how strong. For example, if it is written on a power supply, it does not guarantee that 500 W output energy is real. This is simply the round price set by the marketer. Same with other wattage - 700 watts, 1300 watts. These are all beautiful numbers that attract attention.
Typically, efficiency is written on more or less decent blocks. The middle and middle class models will have 80 Plus certification (bronze, silver, gold, platinum). This means that the efficiency of this model is more than 80%. The higher the certification level, the higher the efficiency percentage. For example, the bronze model would have an efficiency of 82–85% of the specified figure, while the gold version - 90%. Below is a plate showing the percentage of efficiency load of various degrees. For models that cannot offer certifications, efficiency is typically 75% lower.
It turns out that you will buy a 600 W PSU without a certificate and get 450 W power. This moment is taken into consideration when purchasing a computer "engine", because very often this detail is ignored and you are surprised by the frequent shutdown of a loaded computer. Today, most PSUs are 80 Plus Bronze certified, such models can be considered a reasonable minimum. Blocks without a certificate are dark horses - who knows how much power they will have.
The golden rule
The next issue to consider is the level of usage of your PSU. Often, due to budget problems, gamers take the energy of the equipment very tightly. We assembled a 430 watt power consumption system and received a 550 watt model with "Bronze" certification. The system element works, allowing you to start a computer and play games, but constantly work on the edge of your abilities. Naturally, due to the maximum load, all elements of the power supply will heat up, the fan will run at maximum speed and rustling noise will come out, while the internal components will exit very rapidly.
So that your "engine" does not die in a year and a half, you should follow one rule - take the rated power more than one and a half (maybe twice) this system needs. For example, you might think (I'll tell you exactly how to do this later) that your system requires 350 watts of power. We multiply by two, we get 700 watts - we are looking for such a model. Even if you lose 20% efficiency, your system will load the PSU at 50-60% in high load mode. This allows the block to fill for longer periods of time to fade, not overheat, the fan does not spin like crazy and the noise will be very low. By using this rule you will spend a little more money, but the system will work for three to five years instead of one year.
Applying Knowledge in Practice
So we have 328 watts consumed by the system. Multiply by one and a half (remember the golden rule!) And we get 492 watts. But we remember that the power supply does not provide 100% of the energy, but only 80% in the case of bronze. This means that by simple mathematical calculations we get the energy required to "paper" 615 watts. This figure can be transported to the next 600 watts and any model for you from Bronze and above, you can get a little more margin - 650 or 700 watts so that our "engine" is loaded at 50-60%.
You just need to calculate the power consumption of your computer, do the same mathematical calculation. Other parameters - cable modularity, lighting, brand, noise level, smartphone application, etc., you choose separately based on your budget and desires.
Quality is the main feature of any power supply. In the 90s all components were rated a good supporter according to their weight, but the simple Chinese learned to tighten the hull with the help of tape-mounted bolts. Now no one can deal with such a "life hack" and there is no need for it. For a long time, the weight of electricity says nothing. In 2016, it is very difficult to determine the quality of construction according to external indications. "Metal Box». «Fan». «Woven Wire»
The three points are, as you can see, interlinked. So get cheap equipment from SeaSonic, ENERMAX and shut up! You will not find it for sale. Therefore, the name plays an important role. The paradox is that there are not many manufacturers of power sources, and companies that make their own logos with ready-made solutions cost a dozen. It all depends on the office itself, ie how well it controls the production process. Therefore, sometimes a state of unhappiness occurs when the quality of a particular model is kept at a consistently high level for the first time. And it is gaining worthy popularity. But after a year or two, under the same name, they would release the block on a separate platform with a low-quality revised "fill". Below is a list of reliable manufacturers, This includes those who are more or less represented in the Russian retail trade. In times of crisis it is difficult to sell expensive blocks worth 10–30 000 rubles. Therefore, retail is mostly filled with simple solutions. In Russia the same ENERMAX is almost complete. As Ostap Bender said, foreigners will help us!
ჩევთ We recommend 20–30% more backup power, not less than 100–150W. If you plan to do this in the future, buy a high-power power supply immediately. It is also worth noting the connection of peripherals while working on computers, various office equipment (if employed), telephones, players, and other external devices.
Computer Power Supply - This information is necessary because the power supply is the most important component of a computer. It works on all other components and the proper functioning of the entire computer depends directly on it.
Again, you do not need a power supply that will be enough power to the end. It should be noted that the power supply may be lower than that declared by the manufacturer. It is also important to understand that configurations can change over time. This is done so that the power supply does not run at maximum capacity. Failure to do so can result in many problems: freezing, self-rebooting, clicking on the hard drive, and shutting down the computer.
