5 tips for choosing power supply
Players often pay little attention to the choice of chassis and power supply when assembling host accessories. Because the players' concept is that as long as the hardware is strong enough, what kind of games can be played, so it is enough, the chassis and power supply are only the final choice. This idea exists in the majority of players. This idea cannot be denied. In fact, the last choice for the power supply is just not to choose an unreliable power supply. For many small white players, whether the power supply is really reliable or not, they can't be sure. Today, I will tell you a few tips for choosing a reliable power supply.
The choice of power supply is actually divided into different groups. The standards for selecting power supply for different groups are different. Some players pay attention to brand, some players pay attention to mute and stability, some players pay attention to efficiency ripple and some players pay attention to structural design. So how do we understand these needs? This requires consumers to understand what kind of people they belong to. Let's take a quick look at the 5 tips for power supply selection.
The brand is heavy mute voltage can not be poor
The first thing an entry-level consumer knows about power supply is the brand. Picking a brand power supply with a good reputation can ensure the operation of the platform. There are many brands in the power supply product line, including cottage brands and regular brands. The power of the cottage brand is often the easiest to recommend to entry-level players by some unscrupulous merchants, and entry-level players must first understand the brand of power products so that they will not be deceived. Clear power supply nameplate
Regarding how to distinguish between cottage products and regular products, in fact, they can be screened very well through the nameplate of the power supply. Regular power supply products will identify the brand, model, specification and version of the power supply on the nameplate. The most important thing is the rated power of the power supply. Some cottage brands do not mark the rated power of the power supply, or only the maximum power and peak power. The products with the maximum power and peak power are not regular power products. Good voltage deviation
Those who understand a little bit will consider the stability of the power supply and the silent performance of the power supply. The power supply has good stability to allow the platform to run stable. At the same time, in terms of heat dissipation, the power supply depends on the temperature control design, heat dissipation scale and fan quality of the power supply. In fact, this requires some experience. If you have insufficient experience, it is best to choose a product with a good reputation.
Efficient and save money, good ripple display quality
At present, players really pay attention to environmental protection, and whether the power supply can bring energy-saving results has become a favorite of many players. A highly efficient power supply product can save players a lot of electricity costs. At present, the most authoritative is the 80PLUS certification, which is a national energy-saving cash incentive program issued by the US Energy Agency and implemented by Ecos Consulting. At the beginning, in order to reduce energy consumption, system manufacturers are encouraged to select and use power supplies with full load, 50% load, 20% load efficiency above 80% and PF value greater than 0.9 under rated load conditions when producing desktops or servers. 80PLUS certification.
Currently 80PLUS certification has 80PLUS white, 80PLUS bronze, 80PLUS silver, 80PLUS gold and 80PLUS platinum, and in 2014 80PLUS titanium gold products also met with players, the conversion efficiency of titanium power can reach more than 94%. At the same time, such a power supply is very expensive in terms of price. Efficient conversion efficiency
The ripple performance of the power supply reflects the quality of the power supply materials. The ripple is mainly related to the capacitance used on the secondary side of the power supply. For capacitors, the filtering capacity of a capacitor is limited, and multiple capacitors are connected in series on a current to allow the current to be filtered multiple times, so that the current can achieve a more pure effect.
To understand the structure of silent cooling fan
Power supply cooling has been neglected by many players, which is also because all power products seem to use basically the same way of cooling. In the process of testing, we can find that the heating value of the power supply is not small, especially in the case of medium and high loads, as the power increases, the internal temperature of the power supply will rise. If the heat dissipation is not timely, unstable conditions may occur for the components, so the heat dissipation of the power supply cannot be ignored. Yuelun's double ball fan
At present, most of the power supply products on the market use ball bearing fans. The ball bearing fans effectively increase the service life of the fan bearings, and thus extend the service life of the radiator. There are also many power supply products that use oil-bearing bearings. Although the noise is low and the manufacturing cost is low, the wear is serious and the service life is far from the ball bearing. Large heat sink for good heat dissipation
The power supply product also has a fanless design, which has strict requirements for the materials used in the power supply. The fanless design does not have a fan to blow away the heat, and the heat is stored inside the power supply, which has a cruel test for the hardware. For heat dissipation, in addition to the internal materials are good enough, there is also the design of the heat sink, a large area of ​​heat sink can effectively conduct heat, so that the materials inside the power supply work better.
Accurate parameter selection high-performance power supply
As long as you choose the power supply, you only need to identify the parameters. For performance, consumers can understand some of the performance of their products through the evaluation of related websites. The most basic rated power, conversion efficiency, these parameters can be understood through the product's outer packaging and nameplate. As a player, the most important thing to know is the rated power and conversion efficiency. Whether it is an entry-level white player or a high-end enthusiast player, the rated power determines the use of platform hardware. Understand the nameplate
At present, mainstream players often choose power supplies with a rated power of 400-500W. Such a power supply can meet the use of most gaming hardware, and it is not a problem for high-performance graphics cards. If you are a power supply product of 300-400W for office machines, it is enough, and for enthusiast players, at least 600W power supply products can be well satisfied. Choose your own power supply product
No matter what kind of player you are, choosing a good power supply product can ensure the smooth operation of the platform. High-efficiency power supply products can make your platform more power-saving, good stability of the power supply can avoid blue screens, crashes, and other problems. Good heat dissipation products can make the power supply last longer. Players must pay attention to these aspects when selecting power supplies. In terms of price, players should not try to be cheap. The power supply product selected in this way will allow you to use it without any problems.
