Does the quality of the power supply also affect the performance of the whole machine?

Of course, if the output voltage of the power supply is unstable or the current is insufficient, the hardware will not be usable at least or the hardware will be damaged. Especially if you want to use dual hard disks or dual optical drives, a good power supply is essential. It is recommended that you buy a brand-name 300w or a higher power supply if you want.

It's not about performance. However, it has a lot to do with the stability of the host.

And the inferior power supply is also a potential hardware killer.

Thousands of dollars of computers were bought. This power supply should not be picked up cheaply.

Don't buy one with better quality.

I'm using it now"The Great Wall"

Of course it affects and it's important.

If the power supply is not good, it is easy to damage other components (such as unstable voltage and current).

Second, the device may be underpowered and cannot be used normally.

Although the power supply is cheap and has a long service life, everyone does not pay much attention to it, but the power supply is like a human nerve center, so it is also indispensable. Therefore, if the power supply is broken, the consequences can be imagined!

Unstable power supply may cause frequent crashes.

Of course, and it's huge.

Oh, yes. If the power supply is not good, it will often crash. That's how my machine used to be.

It will cause insufficient power supply to each component!

That doesn't matter!

Yes. is very harmful.

Problem description: Every time I am ready to disassemble the power supply to unplug the back of the power supply will power me I don't know what the reason is once I went to the computer to ask them that my power supply is a bit old is 250W may have an impact on the stability of the system But the problem is not very big I want to ask whether it is a problem with the power supply or the chassis The system is sometimes not very stable The CPU temperature is about 46 degrees when it is turned on.

My configuration is.

CPU: Sempron AM2 2800+

Motherboard: NF4 Dual Sensitive SLI M2.

Graphics card: Dual-sensitive PCX8018GTO ** version.

Memory: DDR2 512 533 (forgot what brand) HDD: 80G 7200rpm (forgot what brand).

I heard from the people who installed the computer that my power supply has the same number of pins as the motherboard, but it works.

I hope that all the masters will give the little brother an answer, thank you in this time!

Analysis: If the power of the power supply is insufficient, it will often be in an overload state, and the temperature of the power supply will definitely rise; Power supplies that often operate at high temperatures will be very unstable, which is a common feature of all semiconductor devices, which will inevitably affect the stability of the system. In addition, the power of the power supply is insufficient, which often causes the output voltage to be too low, and also causes the whole machine to fail to work normally.

Of course, the case heat dissipation is not good, and the temperature in the box is too high, which will also make the system work unstable.

The specific effects of blindness are as follows:

1. The overall design is not good, and the heat dissipation performance is poor, which may lead to unstable computer work.

2. The actual power and auspicious rate is insufficient, resulting in insufficient power supply of the computer, which often crashes, and greatly damages the hard disk and other accessories.

3. There is no PFC circuit, and the power supply efficiency is low.

4. The power supply has poor anti-interference, may not have EMI circuits, etc., and has not passed the compulsory certification of some countries, which may lead to computer restart and even damage the hardware when other loads are used at the same time.

5. The manufacturing level is low, and the service life is short.

Of course, the main effects are as follows:

It will lead to hard disk failure, such failure can be repaired by software, first check the power supply, and replace a good power supply when repairing the hard disk;

<> will increase the noise, not only the noise of the fan, but also the noise of the sound card;

It will make the performance of the optical drive worse;

It will make overclocking unstable and affect the performance;

Make the display screen have water ripples;

The computer will automatically shut down and restart.

1 The power supply is one of the biggest suspicions that causes the system to restart automatically. When the number of devices in the system increases, the power consumption increases, and the output voltage of the inferior power supply will decrease sharply, which eventually leads to the instability of the system and the phenomenon of automatic restart. Excessive voltage fluctuations can also lead to damage to hard drives and other devices.

2 Memory issues can also cause the system to restart. There is a relatively high chance that a memory error will cause the system to restart. In addition to ruling out poor contact between the memory module and the socket, a quality problem with the memory itself should be suspected.

In addition, setting the CL value of the memory too small will also cause the memory to be unstable, causing the system to restart automatically. Simple solution: If you are using SDRAM, set the CL value to 3, and if you are using DDR, set it to .

If you are using a motherboard with a VIA chipset, it is recommended to disable the memory interleaved execution function.

3 Excessive fluctuations in grid voltage can also lead to system restarts. In addition, if your computer shares a power strip with high-power appliances such as air conditioners and refrigerators, the voltage supplied to the computer will be greatly affected when these appliances are turned on, which is often manifested as a system restart. The best solution is to equip the computer with a UPS to power the computer, and pay attention to other electrical appliances so that they are no longer connected to the UPS.

4 Poor contact with the power outlet. After the power socket is used for a period of time, the elasticity of the reed is slowly lost, resulting in poor contact between the plug and the reed, the resistance is constantly changing, the current fluctuates, the system will naturally be very unstable, once the current does not meet the minimum requirements for the operation of the system, the computer will be restarted. The solution is to buy a good socket with good quality.

Then it depends on what kind of power supply your computer uses, Huntkey calm king power supply has a minimum voltage to the highest voltage (I forgot the specific data), the voltage is unstable between the data, as long as it does not exceed the withstand voltage of the power supply, it will not burn the power supply. An unstable power supply definitely has an impact on the computer. Therefore, in the case of unstable voltage in your home, it is recommended that you go to change the power supply.

It's much better than that fixed-voltage power supply.

Does the power supply refer to the AC power supply, or the power supply within the main unit? If the AC voltage is unstable for a short time, if the host power supply is good or the power supply of the laptop is good, the computer is fine, but if the host power supply is unstable, it will directly cause the computer to restart repeatedly.

Of course, the unstable power supply will affect the computer, for example, the computer will automatically restart and shut down when the voltage is low.

My computer is unstable in power and burns the motherboard (maybe not for this reason?) In short, the power supply is unstable, and I personally feel that it is the same as watching TV on a thunderous day, and many people buy a computer with more than 140 power sockets, anti-static or something, so the computer is unstable and cautious.

Yes. In addition to relying on the operating system, there is also a power supply problem in the operation of all hardware in the computer hardware configuration. When the power supply is very unstable, the service life of the hardware will also be affected under the condition of long-term unstable power supply, which is likely to directly lead to damage.

When the power supply is unstable, it will affect the normal operation of the system. When there is a deviation in the power supply, the system will start the self-protection mode and shut down the computer directly. In this kind of failure, when the power supply problem is not solved in time, the shutdown problem will occur frequently.

When you encounter a power supply problem, be sure to solve it as soon as possible. If you are a desktop user, make sure that the power cable is working.

Of course, the main effects are as follows:

It will lead to hard disk failure, such failure can be repaired by software, first check the power supply, and replace a good power supply when repairing the hard disk;

<> will increase the noise, not only the noise of the fan, but also the noise of the sound card;

It will make the performance of the optical drive worse;

It will make overclocking unstable and affect the performance;

Make the display screen have water ripples;

The computer will automatically shut down and restart.

The power of each component in the computer has the same **, which is the power supply. The power supply must provide a stable, continuous current to all devices without interruption. If the power supply is unstable and the supply is insufficient, the connected device may not work properly.

The following will introduce to you what phenomena will be caused by unstable power supply.

One. Causes hard disk failure:

Causes bad sectors or damage to the hard drive. A bad power supply can easily lead to false bad sectors in the hard disk, and this fault can generally be repaired by software. If the user encounters such a situation, the first thing to do is to check the power supply.

Two. Loud noise.

Increased noise. Not only will the noise of the fan of the power supply itself increase, but it can also cause the noise of the sound card to increase.

Three. Optical Drive Performance:

The optical drive does not perform well in reading the disk. If your new computer or new CD-ROM doesn't read well, it's a problem with the power supply.

Four. Overclocking Stability:

Unstable overclocking. Whether overclocking is stable or not has a lot to do with the quality of the power supply.

Five. The display has water ripples:

There are water ripples on the display. It may be that the electromagnetic radiation of the power supply is leaking out, and the interference is too great.

Six. Auto-restart won't turn on:

The main machine often restarts or fails to turn on inexplicably, which is caused by insufficient power or insufficient power supply of the power supply.

Please add a detailed explanation.

My computer is unstable in power and burns the motherboard (maybe not for this reason?) In short, the power supply is unstable, and I personally feel that it is the same as watching TV on a thunderous day, and many people buy a computer with more than 140 power sockets, anti-static or something, so the computer is unstable and cautious.
