Can my computer s power supply still work Can I use my computer s power supply if it is broken

For you to use it on a new computer, I don't think it will work, because the 2000 power supply should be 150-200W rated power, and now the standard configuration is required to use the 300W power supply. So no, if you want to use it, you may not even be able to turn on the machine!

Your 2000 power supply, I think it's almost time to retire, the general power supply can be used for 3 years, even if the maintenance is good, it will be more than 4 years, so even if it can still be used now, I think the conversion rate of all aspects of function and W is not ideal, and for the current power supply can be said to be the lifeblood of the current host, if the voltage around your home is unstable, the current power supply has automatic power-off technology to shut down immediately, so as to avoid the possibility of being burned out by high voltage motherboard capacitance.

So for your opinion, I recommend not to use it on a newly bought computer, if you want to use it, it is best to use it on a 2000-2003 computer.

Hope mine is helpful to you!

It is not recommended to do this, the new motherboards are all power supply sockets are 24 pins, although the old 20 pins can also be plugged in, but, however, there may be instability.

It depends on the configuration of the machine you want to build, if it's average, it's okay, if it's higher, it's not. For example, Q6600 level U 3650 level graphics card with more than 2G memory and 250G or more hard disk is definitely not good, at least the power supply power is not enough.

I feel that I don't need to change it, and if I change it, it's a waste of money, and if I don't change it, I can buy a power supply to match it with a better configuration

Don't ask JS if you want to change it, his words can't be trusted.

If your Lenovo computer is P3, you can't use it, if it's P4, you can use it, but you have to look at the inscription on the power supply, whether it's 250W, yes, because 200W is really not good, the power is too small, it will bring you unnecessary trouble.

Personal opinion, it is better to change it to a new one. Because now the power supply is 24-pin. The one you bought in 2000 should have been 20 stitches, and it may be unstable to use.

Yes, yes, but the landlord in 2000, it's 2008, it's been 8 years

It is highly recommended that the landlord change the whole machine and still care about a power supply?

The power supply of Huntkey Great Wall is not too expensive, about 150-200 so it is very good.

Changing the owner of the building used the power supply for 8 years is too old.

Absolutely, as long as it's not bad.

It is quite safe to say that there are no problems with long-term use. The main difference between 12V, 2A and 12V, 5A power supplies is the maximum power, the former has a maximum power of 24W, and the latter has a maximum power of 60W. The difference in use is that the maximum output lift current is different, the latter can replace the former, and the former may not be able to replace the latter.

1. Interpretation of the nameplate of the power adapter: 12V on the power adapter refers to the output voltage is DC 12V, and 2A is the maximum current that this adapter can output stably for a long time. If the voltage required by the appliance is 12V, and the maximum current required does not exceed 2A, this power adapter can be used normally. The 12V and 5A power adapter refers to the output voltage of 12V, which can stably output 5A for a long time.

Since the original power adapter of the display is 12V, 2A, it means that the maximum current does not exceed 2A, and the power adapter with a maximum current of 5A can of course output 2A current, so it can be completely replaced by the latter.

2. The big horse-drawn trolley - stable to interpret it in popular terms, 2a is a pony, 5a is a big horse, the search display is a small car and a pony just match, with a big horse-drawn trolley - overkill, but more stable. So you can understand that as long as the voltage is the same, the maximum current required by the appliance does not exceed the output current of the power adapter, and it can be used instead.

For another example, the previous Android phone chargers were all 5V, the output current of the positive and drain sum was 1A, and the output current of some was 2A, and the 1A charger could be replaced with 2A if it was broken. The small horse does not move the cart, the desktop hard disk plus the easy drive cable is a mobile hard disk, but it needs an external 12V power supply, which generally requires 2A current, if the external power supply is 12V, 1A, the general hard disk can not read and write normally (I have personally tested it).

To sum up, the original 2A power adapter of the display is broken, and it can be replaced with 12V and 5A, which is more stable and reliable.

It can be plugged into a power supply without affecting the battery.

Reason: 1. Most notebooks now use lithium batteries, when the battery reaches a full state, even if it is plugged in, there is no charging current, and the battery will not work, so the loss is very small.

2. If you often plug and unplug the battery on the notebook, it will keep wearing out the interface, which is easy to damage the battery interface in the long run, and it is easy to bring dust into the computer, which outweighs the loss. Especially in the case of live electricity, it also hurts the battery.

3. The battery is not only carried out but also comes in handy, when encountering a sudden power failure, it can protect the computer data from being lost due to power failure, and it also protects the hard disk.

Note: However, it should be noted that if the battery is not used for a long time when plugged in, it may cause the battery to passivate, so it is recommended to use the battery power occasionally.

In addition, if the individual computer is not plugged into the external power supply, it will always be in the power-saving state, resulting in slow playing games and office cards, of course, this is also a setting, which can be adjusted in the power management of the computer.

According to the overall power consumption of the computer, the model and power supply should be decided.

1. To replace the power supply, the rated power of the power supply needs to be greater than the overall power consumption of the computer. If it is lower than the overall power consumption of the computer, it will be prone to hardware failure or repeated restarts;

2. There are standards for all kinds of interfaces of the power supply, and the interfaces of the new power supply will be compatible with the old power interfaces;

3. Miscellaneous power supplies are generally false standards, and their actual rated power is smaller than the calibrated power.

It's okay to keep the laptop plugged in.

Many people think that 100% full charge is "overcharge", but this is not true. The real problem with the use of 100% fully charged plug-in cables is "storage passivation", which is especially severe when fully charged. However, for users who charge and discharge their batteries at least once a week, this problem is basically a concern.

But if you plug in the power all year round, it will definitely produce passivation. At the same time, high temperatures can greatly accelerate the passivation and aging process. Therefore, for some gaming laptops, the battery life is basically very low, but this can't be helped, because many people buy gaming laptops to play games, and if they are not plugged in, the performance of the notebook cannot be fully played.

I would also like to remind students who work tirelessly to make the battery use for a few more days that if it is not plugged in, the performance of the notebook will decrease. Although we can adjust the power management strategy to try to give the notebook a chicken blood. However, when EC finds that the small water pipe of the laptop battery cannot meet the needs of several large power consumers, in order to avoid the unpleasant thing of black screen restart, it will take the initiative to limit the frequency.

Especially when the game book is playing games, it is better to plug in the power supply.

Battery over-discharge has a great impact on the battery, and the over-discharged battery needs to be reactivated for too long, which is very troublesome. Of course, zero power is not overdischarged, and it may be overdischarged after a period of vacancy after zero o'clock. Friends must pay attention.

Dear I will answer this question for you, dear, dear, the computer should be plugged in all the time, oh dear, to prevent over-discharge when unplugged, dear dear, the following are the benefits of the computer being plugged in all the time, pro: benefit 1: It can make the battery age longer and increase the service life of the battery.

The batteries all have protection circuits that will automatically stop when fully charged, and there are also battery management chips in laptops that are responsible for managing the charging and discharging of the battery. When the laptop's power management chip detects that the battery is fully charged, the charger does not recharge the battery and instead provides power to the laptop**. This means that when the battery is fully charged, the charger will power the laptop.

Powering power is not the same as charging, so don't worry about overcharging. "Advantage 2: It is helpful for the operation of the computer CPU and can solve some of the problems of notebook lag, so it is better to plug it in.

Yes, there is only a small standby voltage after the computer is turned off, so the power consumption is very low!

Yes, the current batteries are lithium batteries and have no memory effect, so even when the laptop is not in use, it can be plugged in and charged all the time without damaging the battery.

And now laptops have battery management technology, if the computer's lithium battery is fully charged, then the electricity used by the computer will be directly provided by the power cord, even if it has been plugged in, as long as the battery is fully charged, it is only in the standby state, and the battery will not be used.

A laptop's battery doesn't charge until it drops below a certain number. Since the laptop is always plugged in, charging after the battery is reduced will not count towards the number of charges. The laptop is always plugged in to charge and does not hurt the battery.

When using the laptop in an environment that provides a stable power supply, it is recommended to use an external charger, and the battery will be charged automatically.

Lithium batteries have no memory effect, and ASUS original lithium batteries have safety mechanisms such as preventing overcharging, preventing over-discharge, charging temperature control, etc., so in an environment with a power supply, you can plug in the power supply and use it.
