When purchasing and assembling a computer power supply, the most important thing is to understand how much power your computer requires. PHP editor Youzi will provide step-by-step guidance to help you calculate the required power and choose an appropriate power supply. To avoid the waste of under- or over-powering, read on to learn how to choose the best power supply for your specific needs.
The power supply for assembling the computer should be a national standard brand product with a power that is at least 1/3 greater. If the power consumption of the host is 350 watts, then a nominal power supply of 450 watts or more should be used
First of all, I am happy to answer your questions.
Secondly, let’s talk about the problem. It’s very important, very important, very important. I say important things three times. The power supply of your computer is like the power supply in your car. Without it, you can’t start the fire. You Is it important? Back to the topic, let’s talk about the importance of power supply. We must first consider how much power your computer’s five major hardware uses, and then the power supply we equip must be greater than the power of the five major components, otherwise your computer will continue to cycle. After restarting, the next thing is the brand. I personally recommend Huntkey (the preferred power supply for brand-name machines) and Great Wall (the best choice for DIY). Haha (don’t blame me, I personally like these two)
I hope my answer can help you!
1. Power, first look at the power of your power supply hardware, and look at the rated power of your graphics card and CPU.
The simplest algorithm is to add the graphics card and CPU, plus 200W. If the power is not enough, no matter how good the brand is, it will pale in comparison.
Excessive performance will feel like a waste.
2. Check the size of the chassis to see if it can fit. If it can’t fit, replace the power supply and chassis, which is a bit troublesome!
3. For wires, you can choose full modules, straight-out cables, or semi-modules. Full-module assembly is simpler.
4. Power supply efficiency and quality. Nowadays, power supplies have various solutions, such as DC-DC, EMI filters, capacitors, etc.
Solid capacitors in power supplies are better, and single-channel 12V current is better. A friend who doesn't install the computer often can't understand many parameters. Simply buy a good power supply with confidence. Look at the brand. Taiwanese and American Corsair products are not very cost-effective. In fact, they are a bit exaggerated. Domestic power supplies include Great Wall, Huntkey, Cooler, etc. to choose from.
My friends around me use Great Wall power supplies the most. Domestic power supplies from Great Wall are used in civilian, military, aerospace, supercomputers, servers, etc., which shows that they are of excellent quality. A 400W bronze power supply for home and office use is sufficient. Games, etc. require more than 500W, and both bronze and gold medals are acceptable. The efficiency and quality of gold medals will be better than bronze medals.
1. The rated power should be enough. If it is too small, it is not enough. If it is too large, it is a waste. If you consider the need to upgrade your computer hardware in the future, choose a power supply with a higher power rating than the one you used previously.
Use Master Lu to calculate the power required by the host. On the computer with "Master Lu" installed, open Master Lu, click "Power Consumption Estimation" on the left side of the main interface, open the "Power Calculator", and fill in all the hardware of your computer host in the power consumption table, that is Display the power consumption of each hardware and the power consumption of the whole machine, such as 100W.
1. The sum of the average power consumption of each computer hardware is 100W. Generally, an insurance factor of 10-20% needs to be added. Add 20%. 100W 100W×10%=110W.
2. The load power of the power supply is best controlled at 60-80% of the rated power of the power supply. The control rate is calculated as 70%, 110W÷70%=7.14W.
This computer uses a 157.14W power supply as well.
Use the method above to calculate how many watts of power supply you should buy.
2. The interface is sufficient. Depending on your hardware, check whether the SATA serial hard disk interface is sufficient and whether there is a 6-pin graphics card interface. Some graphics cards even require two. If the power supply is not available, you will need to use an adapter to convert it, which is troublesome.
3. Check the power supply certification. There are six levels of power supply certification standards: white, bronze, silver, gold, platinum and titanium. The higher the grade of the power supply, the higher the conversion efficiency, the more energy-saving and reliable the power supply, and the safe and stable operation.
4. Choose a good brand. The quality of power supplies varies. It is recommended to buy high-quality power supplies from big brands, such as Huntkey, Great Wall, Antec, Cooler Master, Delta, Haiyun, FSP, Kangshu, Jinhetian, Xingu Power, etc. Some small brands and no-name power supplies have false power ratings, shoddy components, poor filtering, and unstable voltage, which can easily lead to frequent computer failures or even hardware damage. For example, Huntkey, Great Wall, Antec, Cooler Master, Delta, etc.
5. If your local mains voltage is normal (220V), buy an ordinary standard power supply. If the voltage is unstable, buy a wide power supply (160V-250V, 90V-264V
If we talk about the lifespan after it is worn out, this is not necessarily true. It may break down in one year, or it may not break down in ten years. But in terms of performance life, the longest is estimated to be 5 years. In the future, even with the current mid-to-high-end configurations, even the web page and QQ may be stuck
In fact, many computers have been eliminated by the operating system. The new operating system has high hardware requirements, and old computers are too slow to run the new operating system. Just be eliminated. This is the trend and law, and it is also the need of software and hardware manufacturers and dealers.
When assembling the computer power cord, you need to connect the power cord to the power supply and the computer host. The following are general steps:
1. Disconnect the power supply: Make sure the power supply and computer host are powered off, and unplug the power plug.
2. Connect the power supply: Insert the plug of the power cord into the corresponding socket of the power supply. The socket on the power supply is usually located on the back of the power supply and has a specially shaped slot to ensure that the plug is connected correctly.
3. Connect the host: Look for the power interface on the back of the computer host, usually located on the top or bottom of the host. Plug the other end of the power cord into the power socket of the computer host.
4. Fix cables: Use cable ties or wire bundles to fix the power cord around the host to ensure that the cables are neat and safe.
5. Check the connection: Make sure the power cord is tightly connected to the power supply and computer host socket without looseness.
6. Repower the computer: Insert the power plug into the power socket and turn on the power switch to power the computer.
When connecting the power cord, please make sure to choose a power supply that meets the hardware requirements of your computer, and ensure that the power cord is properly installed and assembled to ensure a secure and safe connection. If you encounter any problems during connection, it is recommended to refer to the manual of the power supply or computer host, or seek professional help. Also, be careful when assembling the power cord and make sure to follow relevant safety operating procedures to protect your own safety.
Within a budget of less than one thousand, we need to choose suitable computer accessories according to our own needs.
First, determine the compatibility of the motherboard and processor, and choose appropriate memory and storage devices. It is recommended to choose a large-capacity hard drive or SSD. For graphics cards, you can choose some cost-effective entry-level products. Other accessories such as power supplies, chassis, radiators, etc. also need to pay attention to quality and adaptability. Finally, choose the appropriate components to assemble your computer based on your needs and budget.
It may be a power problem! It's very simple. Unplug everything that's plugged into the motherboard from the power supply. Then use a paper clip on the 20 4-pin end to connect the green wire to any black wire. If the power supply fan is spinning, then The power supply is good and can be ruled out.
After confirming that the power supply is good, connect the motherboard power supply and CPU power supply. If the independent graphics needs power supply, also connect it. However, if there is integrated graphics or nuclear graphics, it is recommended to unplug the independent graphics first (click When it lights up, it shows independently on top). Then unplug the hard drive indicator light, power indicator light, and restart button (leave only the power-on cable), and then turn on the computer. If it cannot be turned on, it means that the connection between the indicator lights, the reset button, and the power-on button is wrong. !
The following aspects need to be considered when selecting a power supply:
1. Power: The power of the power supply must be sufficient to meet the needs of the entire computer system. It is generally recommended to choose a power slightly higher than the actual demand. Ensure the stable operation of the computer. Generally speaking, ordinary office computers require a power supply of 300W-500W, and gaming computers require a power supply of 500W-750W.
2. Brand and quality: Choosing a well-known brand and high-quality power supply can ensure the stability and life of the power supply and avoid failures or safety issues. Common brands include Corsair, Antec, Cooler Master, Zhenhua, etc.
3. Interfaces and cables: Choose appropriate interfaces and cables according to your own needs, such as SATA interface, PCI-E interface, etc. At the same time, the cable length should also take into account the chassis size and wiring conditions.
4. Efficiency: A high-efficiency power supply can improve energy utilization, reduce energy waste and heat generation, and also extend the life of the power supply. It is generally recommended to choose high-efficiency power supplies with 80PLUS certification and above.
5. Noise: Choosing a low-noise power supply can improve the stability and user experience of the entire system. It is generally recommended to choose a power supply with a larger fan diameter and lower rotation speed.
In short, when choosing a power supply, you need to comprehensively consider it based on your own needs and budget, and choose a power supply with an appropriate brand, power, interface, efficiency, noise, etc. At the same time, attention should also be paid to the safety and stability of the power supply to avoid failures or safety issues.
First of all, we need to confirm what kind of unresponsiveness this is.
1. The power fan does not spin when the computer is turned on.
Solution
Check the power cord Is there any problem? Have you connected the power strip? Is it firmly plugged in?
Check whether the cpu motherboard power supply interface is plugged in correctly! Even though it's facing the wrong way, it won't turn on even though it's plugged in.
Check whether the power supply is normal. Use a wire to plug in the green and black wires of the motherboard's power supply cable. After plugging in, the fan rotates to prove it's normal.
2. When the power supply fan is turned on, the screen does not display.
Troubleshooting: When the computer is turned on normally, the screen does not display. Press the key on the 7 keypad a few more times. If the light on the keypad turns off and on, it means the computer is running normally. It's just that the screen doesn't display. Now check to see if the display output line is connected to the graphics card normally! Graphics card graphics card! superior!
If the keypad light above does not go out when pressed, it is usually because the memory module is not inserted securely. If it still does not work, there is a problem with the motherboard or CPU.
