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.

Recently, Liupanshui, Guizhou

A female college student cleans the dormitory.

Because oxalic acid bought online reacts with washing powder.

Collective poisoning of roommates

According to classmate Tian, the dormitory was swept out of worms, so she bought oxalic acid online for cleaning, and also brushed the floor with washing powder. After closing the door and sleeping, the two gases reacted, and four people were poisoned and became dizzy and vomited. At present, the symptoms have been alleviated.

Many netizens said

Don’t fool around if you don’t know chemistry.

Some netizens said

After cleaning, you must open the window for ventilation.

There are also some netizens reminding me.

Never use two kinds of detergents together.

Many people are doing cleaning.

Often in order to pursue cleanliness, cleanliness, sterilization and so on.

Will use a variety of disinfectants and detergents at the same time.

But pay attention.

Many disinfectants and detergents cannot be used at the same time.

You only need to use a single one when you use it.

in recent years

So news of poisoning happens from time to time.

The most accidents in the news are the mixture of 84 disinfectant and toilet cleaner. According to the doctor, when 84 disinfectant meets toilet cleaner, it will produce irritating gas, mainly chlorine. Different concentrations of chlorine have different effects on human body, and the concentration is too high or life-threatening. For example, in an environment with small area and poor ventilation, the chlorine concentration produced after using 84 disinfectant and toilet cleaning forest is high, which will affect human body in just a few minutes and damage human skin and mucosa, such as irritating eyes and nose, causing severe cough, chest tightness, tight breath, difficulty breathing and so on. If the inhaled chlorine concentration reaches 120-180mg/m3; , it will cause serious damage to human body, and the chlorine concentration reaches 300 mg/m3; When inhaled, it may cause fatal injury.

Toilet cleaner can’t be used together with 84 disinfectant.

Toilet cleaner can’t be used together with Tianna water.

Tianna water, also called banana oil, is a colorless, transparent and volatile liquid, which has the functions of cleaning, dilution and emulsification, and is generally used for cleaning. Tianna water is a mixture of various organic solvents, mainly toluene and xylene, which can be brought into human body through skin and respiratory tract after volatilization. Xylene mainly inhibits the central nervous system of human body, showing dizziness and chest tightness. After inhaling high concentration for a short time, the anesthetic effect on central nervous system and autonomic nervous system and the stimulation effect on mucosa may be accompanied by liver, kidney, heart, lung and other organ damage.

When cleaning the home,

When using various cleaners and disinfectants

We should do the following.

1. Choose carefully: according to the object to be cleaned, choose the appropriate detergent. Acid cleaners and alkaline cleaners cannot be mixed.

2. Dilute and wear a mask before use: All kinds of cleaners and disinfectants should be used after dilution in strict accordance with the dilution ratio listed in the instruction manual. At the same time, it should be noted that masks should also be worn and protected when diluting.

3. Label: The diluted detergent and disinfectant should be labeled on the bottle body, and the name and purpose should be clearly written to prevent confusion.

4. Pay attention when using: When using various cleaners and disinfectants, pay attention to wearing protective equipment, such as masks and face screens. At the same time, you should also choose suitable cleaning tools, and you must not operate by hand.

5. Return to the original place after use: After using each cleaning agent and disinfectant, cover the lid and store it in the designated place to avoid taking it by mistake and avoid eating it by children or pets at home.

Xiaobian reminds me here

Cleaning is certainly a good thing.

But also pay attention to the methods.

Don’t try to

Pursue cleanliness and sterilization blindly.

And various disinfectants and detergents are mixed.

Special feature of 1905 film network Every Friday, the world’s best films in Universal Cinema continue to be broadcast, and on May 5, the film "007 Breaking the Sky" will be broadcast for you.

James Bond failed in his mission? See how he strikes back.

As a masterpiece commemorating the 50th anniversary of 007 series, The Story of 007 is the first IMAX film in the history of 007, and also the third 007 starring the sixth generation of 007 actors.

In 2013, the film "007 Breaking the Sky" was shortlisted for three nominations, including the 85th Best Photography, and finally won the Best Original Song Award and the Best Sound Editing Award.

The image of this "gentleman" agent, which has been passed down for more than 50 years, has long been deeply rooted in the hearts of the people.

Wonderful stories, carefree movements, cool cars, beautiful bond girl and many other elements have made the 007 series films enduring after six generations of actors.

The honor of the nomination of "Best Photography" made more people pay attention to the lens performance of "007 Breaking the Sky".

As the director’s first attempt at an action film, this film is often shot by multiple machines at the same time.

In an outdoor scene shot from Istanbul, four cameras were used, one near daniel craig, one for the middle shot, one for the distant view, and the last one moved as needed.

In the dark corridor, a beam of light hits Bond’s face. This contrast between light and shade not only highlights the director’s precise use of lens and light, but also depicts Bond’s cold agent image delicately.

The film’s "ride" is of great concern to viewers who are both fans of 007 movies and car fans.

In the film, the 1963 Aston Martin DB5 driven by James Bond pays tribute to the DB5 that first appeared in the 1964 film "007: Goldfinger", and even the license plate number is the same, which is also the most famous of all Bond cars.

In the previous 007 movies, DB5 has many high-tech equipment added by Dr. Q, including bulletproof body, fuel nozzle, smoke launcher, machine gun, rotating license plate, tracking device receiver, and the most popular ejection seat.

The return of this traditional Bond car also makes Dr. Q’s return in "007 Breaking the Sky" more logical.

The most heartbreaking part of this film is Mrs. M’s "leaving".

In 1995, the actor began to play the role of "Mrs. M" in the 007 series movies. After a lapse of 17 years, Mrs. M, who she played, finally made a curtain call in "007".

As the direct leader of James Bond, Mrs. M is not loved by "subordinates", but gives people a sense of severity, rigidity and inhumanity, and often criticizes Bond.

Although on the surface, the two men are often "at odds", Bond respects M very much, and M is proud of having such a good staff, often praising him in front of others, and thinks that Bond is the best of all agents.

Mrs. M’s curtain call in the film was called "Real bond girl" by many fans.

After more than half a century, the legend of James Bond continues. With handsome image, straight suit and excellent ability, 007 has long been not only a movie and a code name, but also a hero that many viewers yearn for.

At 22:20 on May 5, lock in the movie channel Universal Cinema to see how Bond can get back on his feet after the injury and stop the shocking plot.
