How big is the power supply? I believe this is a problem that many DIY players will encounter when purchasing power. Most people’s solution is to follow the crowd, and I will choose how big others choose. In addition to seeking help in forums and post bars, the sales volume and evaluation of e-commerce platforms are also one of the reference standards.

Although this method can solve the problem of "which power supply to buy" temporarily, it can’t answer the fundamental question of "how much power to buy" in the long run. You can’t ask others for help every time you install the machine, can you?

So is there a way to do it once and for all without asking for help? Today, I will teach you a trick to easily choose the power supply suitable for your computer.

Let’s popularize the basic knowledge before teaching you how to choose the power supply suitable for your computer.

Our computer isIt is composed of CPU, graphics card, motherboard, memory, hard disk, peripherals and other hardware. When the computer is running, all parts of the hardware need to consume a certain amount of power. Generally speaking, the power consumption of CPU and graphics card is the highest, accounting for the vast majority of the overall power consumption of the computer.

Whether the computer can run stably is not only affected by the hardware itself, but also by the power supply that provides them with electricity.

Simply put, if the power consumption is higher than the overall power consumption of the whole machine, the computer will run stably; When the power supply is lower than the overall power consumption of the whole machine, it will be unstable. Therefore, it is particularly important to choose a power supply with sufficient power.

In fact, the solution is very simple, just buy a power supply with high power supply, but don’t forget that the higher the power supply often means the higher the price, and you need to pay more money for the high power supply.

The power calculator is good, but the update is not in place.

So, how can we calculate the overall power consumption required by the whole machine?

There are two ways, one is to calculate the overall power consumption of the whole machine through the known power consumption of each part of the hardware. Obviously, this method is time-consuming and laborious, and it is necessary not only to find the power consumption of each part of hardware, but also to add them one by one, which inevitably leads to the risk of mistakes.

The second method is obtained through a power calculator. There are some power calculators on the Internet. You can automatically calculate the required power by selecting the configuration of your computer, which is very convenient.

But most of these calculators are old, and the support for many new models of hardware is not in place. You may not find your own hardware at all.

PSU Calculator to find out.

The following is the key point that the author wants to talk about. Since the power calculator is more convenient than manual search, is there a power calculator that supports the existing hardware better?

The answer, of course, is yes, which is also the purpose of this paper. It is a power calculator from Cool Extreme.

This power calculator is called PSU Calculator, which can only be found from Cool Extreme. The English interface is not very friendly to us, but fortunately, the support for new hardware is good, and it can be found in 8-generation Core and 10-series graphics cards.

After opening the link of PSU Calculator, you can see a very detailed table, including motherboard, CPU, memory, graphics card, hard disk, keyboard and mouse, fan and other devices, and you can even overclock the frequency of CPU and graphics card to calculate the appropriate power supply. I have to say that this power calculator is very careful and worth learning from domestic manufacturers.

How many watts of power do the high, medium and low platforms need?

After knowing that there is a good thing called PSU Calculator, let’s try to calculate how many watts of power are needed for high, medium and low platforms based on the current mainstream hardware configuration.

1. High-end platform: i7-8700K+GTX 1080

Let’s take a look at the high-end platform of i7-8700K+GTX 1080. Other configurations are fixed as two 8GB memories, a SATA SSD+ and a 7200 rpm mechanical hard disk.

After selecting the configuration, click Calculate in the lower right corner to calculate the required power supply.

It can be seen that there are two powers in the lower right corner, one is Load Wattage, and the other is Recommended PSU Wattage. Load Wattage refers to the typical load of this configuration, such as the power required for running a 3D game, and Recommended PSU Wattage is the recommended power, which we shall take as the standard.

The typical load of this configuration is 401W, and the recommended power is 451W W. It can be seen that the power required by this high-end configuration is not as high as we thought, and the power supply of 500-600W can meet it.

For example, Hangjia’s JUMPER500 power supply has a rated power of 500W, and has passed the 80PLUS white-label certification, with 12V single-channel 40A current output and active PFC+ dual-transistor forward scheme. The price of 299 yuan is very cost-effective.

2. Mid-range platform: i5-8400+GTX 1060

For the mid-range platform, we take the i5-8400+GTX 1060 as an example. Other configurations are still fixed as two 8GB memories, a SATA SSD+ and a 7200 rpm mechanical hard disk. Calculated by PSU Calculator, this configuration only needs 362W W.

We can choose a 400W power supply for this mid-range configuration. For example, this Longba 400 power supply of Jinhetian has a rated power of 400W, adopts an enhanced 12V output (18A), double copper PCB design and a 12cm hydraulic fan. The power supply is stable and the heat dissipation is more efficient, and the price is only 159 yuan, which is very affordable.

3. Low-end platform: AMD Ruilong 2200G+ set display.

Here we positioned Ruilong 2200G as the living room entertainment center, so we didn’t increase the solo display. The recommended power calculated by PSU Calculator is 212W, and the power consumption is very low, so it is enough for us to choose a 300W power supply.

For example, the C5 power supply of Xingu, a nuclear-powered cruiser, has a rated power of 300W, a 12V output of 252W(21A), accounting for 84%, and the peak power can reach 400W W. Moreover, it adopts a 12cm PWM intelligent temperature control fan, which can reduce noise while providing large air output. The price is more affordable, only 119 yuan.

Well, the above is the author taking the current mainstream configuration as an example, and calculating the required power through PSU Calculator to choose the power supply he needs.

The purpose of this paper is to tell you that you can use PSU Calculator as a small tool when purchasing power supply, so you don’t have to ask for help from others or calculate manually. Interested friends may wish to collect it and try it first.

　　Cctv newsAt present, a new round of scientific and technological revolution and industrial transformation is booming. How can Beijing promote the construction of a national science and technology innovation center and accelerate the establishment of a science and technology innovation center with global influence?

　　On September 19th, the State Council Press Office held a series of press conferences of provinces (autonomous regions and municipalities). Chen Jining, deputy secretary of the CPC Beijing Municipal Committee and mayor of Beijing Municipal People’s Government, invited scientists and entrepreneurs from all over the world when answering questions from CCTV reporters. He said: at present, mankind is facing many global problems and challenges. These problems require the joint efforts of scientists from all countries and increase exchanges and cooperation between them. Beijing sincerely welcomes scientists and entrepreneurs from all over the world to come to Beijing for development, and Beijing will provide more convenient scientific research and living conditions.

　　The biggest advantage of Beijing is the advantages of talents and science and technology. In terms of innovative resources, Beijing is rich in talents and scientific and technological resources. There are more than 90 universities, more than 1,000 scientific research institutes, 120 national key laboratories, 68 national engineering technology research centers, about 860,000 college students and 25,000 national high-tech enterprises in Beijing. In terms of quality, Beijing’s innovation resources are better. Half of the top talents’ best disciplines and best laboratories are in Beijing, and Beijing’s R&D investment intensity is 6.17%, ranking first in the country. About half of the first prize of national scientific and technological achievements and the top ten scientific and technological progress in China come from Beijing every year.In terms of innovation vitality, Beijing is also a well-deserved city with the most active innovation and entrepreneurship in the world.There are about 200 innovative enterprises in Beijing every day, and the amount of venture capital and the number of cases account for about 30% of the whole country.If we look at VC/PE investment in technological innovation, Beijing is second only to Silicon Valley as a global city.In the latest list of unicorns, 82 enterprises in Beijing were selected, accounting for nearly half of the country. In some advantageous innovation fields, Beijing’s characteristics are even more obvious. For example, in the field of artificial intelligence, 60% of the country’s artificial intelligence talents gather in Beijing. Among the top 100 global artificial intelligence enterprises, there are 6 in China, including 5 in Beijing.

　　In the face of a new round of scientific and technological revolution and industrial transformation, Beijing, as a national scientific and technological innovation center, bears a major historical mission and national responsibility. Therefore, scientific and technological innovation is the most important work here, and three aspects of work are mainly grasped.The first is the construction of innovation system. The second is to innovate ecological construction. The third is the construction of innovative culture.

　　In terms of innovation systemBeijing has made a series of institutional breakthroughs in scientific research management, performance evaluation, rights and interests of scientific and technological achievements, long-term capital support, etc. All these are to solve some deep-seated problems in scientific and technological innovation, with the aim of stimulating the enthusiasm and creativity of all kinds of innovative subjects. Beijing has issued 28 regulations on scientific research projects and funds management, giving researchers more tolerance and trust, so that scientific research funds should be spent well as well. Beijing has established a number of new R&D institutions, such as Beijing Institute of Quantum Information Science, Brain Science and Brain-like Science Research Center. Through the construction of these new R&D institutions, the organization and management of scientific research can be solved, and a long-term stable support and an open and flexible employment mechanism can be formed. Beijing has also specially established a mother fund for scientific and technological innovation with a scale of 30 billion yuan to stimulate and attract social investment, which can be enlarged to 100-150 billion yuan. The most important feature of this fund is that its capital investment period can be 10-15 years, which is the longest investment innovation fund. Through the establishment of this parent fund, it is necessary to solve the problem of insufficient patient capital and long-term capital, and encourage innovative subjects to carry out long-term sustainable innovation in hard technology and deep technology.

　　Recently, Beijing is speeding up the study and promoting the revision of the Regulations on Promoting the Transformation of Scientific and Technological Achievements, which is a local legislation. It is hoped that the ownership of scientific and technological achievements, the distribution of transformation income, and the exemption from due diligence will be clearly defined in the form of law, and the core is to solve the property rights problem of scientific and technological achievements. The property right of scientific and technological achievements has been transformed from the ownership of state units in the past to the individual ownership of scientific and technological personnel, and the state can participate in the distribution, but the property right can be personal. Some scientists say that if this regulation is promulgated, it will realize their long-awaited "Children born by themselves can cultivate themselves into adults.”。

　　In terms of innovation ecologyBeijing mainly solves two problems. One is to strengthen the spatial ecological layout, that is, to promote the high-intensity agglomeration of various innovative elements in a limited space, so that chemical changes occur among these innovative subjects. The key point is to do a good job in the construction of "three cities and one district". The three cities are Zhongguancun Science City, Huairou Science City and Future Science City, and the first district is Beijing Economic and Technological Development Zone.

　　Zhongguancun Science City systematically lays out the basic frontier and key core technologies, improves the ability to open and gather global innovation resources, strengthens the city’s innovative image, and builds the original innovation source and the main position of independent innovation with global influence.

　　Huairou Science City focuses on the long-term scientific layout, and builds large-scale scientific devices such as comprehensive extreme condition experiments, numerical simulation of the earth system, and high-energy synchrotron radiation light sources to build a comprehensive national science center.

　　In the future science city east area, the current work focus is to revitalize the stock resources of central enterprises, introduce diversified innovation subjects, and create an "energy valley"; The Western District promotes the integration of science and education in Shahe University Town, especially taking Zhongguancun Life Park as the explosion point of the development of the medical and health industry in the city, and deepening the reform of the operation and management system of the park through the open introduction of professional teams.

　　Not long ago, Beijing Economic and Technological Development Zone completed its expansion, mainly to undertake the technological achievements of transforming the "three major science cities", build an open and innovative industrial cluster and a high-tech industrial main position, and at the same time link up with Tianjin and Hebei’s innovative industrial chains.

　　The second is to strengthen the ecological construction of the industrial chain, mainly relying on core enterprises, underlying technologies and public innovation platforms. By strengthening the construction of supporting conditions, the innovative elements of the industrial chain will be gathered to promote mutual support and collaborative innovation among industries. In 2017, Beijing issued guidance on the development of 10 high-tech industries, including the new generation of information technology, and also formulated corresponding supporting policies such as finance, land and talents. For example, the land policy, the full implementation of life-cycle management of industrial land, the implementation of flexible annual land transfer, first rent and then let, industrial land can only be used in industry, innovative land can only be used for innovation, support the construction of standard factory buildings for lease to enterprises, which not only greatly reduces the cost of enterprise land, but also prevents land hoarding and speculation. For example, in terms of talent policy, Beijing has greatly broadened the scope of talents around innovation chain, not only paying attention to scientists, but also bringing entrepreneurial investors, engineers, intellectual property lawyers and product managers into the innovative talent system to support them.Since 2018, more than 3,500 talents have gone through the introduction and settlement procedures.At the same time, Beijing is also highly concerned about solving it.The height of talentsProblems, focusing on the introduction and training of a number of.Strategic scientific and technological talents, leading talents in science and technology and leading talents in the industry.. Recently, more than 3,000 apartments for talents and experts have been specially set up in Beijing to support them.　　

　　In terms of innovative cultureVigorously strengthen the creation, protection and application of intellectual property rights, set up intellectual property courts, punish violations of intellectual property rights according to law, and significantly increase the illegal cost of intellectual property rights infringement. Recently, Beijing has specially established an intellectual property insurance system for small and medium-sized enterprises to improve the ability and level of intellectual property protection. In addition, Beijing has also increased its efforts to "send charcoal in the snow" for small and micro science and technology enterprises, and set up a financing guarantee fund of 10 billion yuan to improve the financial services for science and technology-based and innovative enterprises through angel investment, investment-loan linkage and intellectual property pledge loans.

　　Recently, Beijing has formulated and implemented a plan to accelerate the construction of application scenarios, and released the first batch of ten major application scenario construction projects with a total investment of more than 3 billion yuan, relying on urban governance, government services, and key projects of major events such as the Winter Olympics, the World Expo and Daxing International Airport. At the same time, a number of new application scenarios are collected for Zhongguancun innovation subjects every year. Beijing also pays special attention to strengthening innovation education, raising citizens’ awareness of innovation, making respecting knowledge and innovation become the consensus of the whole society, and creating an innovation culture that encourages innovation and tolerates failure.

　　In a word, by constantly improving the innovation system, optimizing the innovation ecology and advocating the innovation culture, Beijing has the confidence, conditions and ability to build itself into a scientific and technological innovation center with global influence.
