Why do motherboard capacitors break, and what should I do if motherboard capacitors are broken?

How long will it take to break Generally speaking, it depends on the quality of the motherboard Then it is the surrounding environment, why it will be bad Because the voltage will be bad, because the ambient temperature will be bad, and the quality of the motherboard will be bad if it is not good.

Capacitance quality. There is also the use.

Unreasonable, usually Internet café computers prefer to explode. Halo,

Then you still need to ask - the temperature is high!! The high temperature in the case will cause the acceleration of the degradation of various capacitors on the motherboard and other hardware, so it is best to add several case fans to the computer with high configurations!!

The highest probability of damage to the motherboard is the MOS tube of the power supply circuit, followed by the power supply circuit capacitor.

Because the CPU power supply circuit of the motherboard is designed with MOS + inductance + capacitor, there is generally only 80%-90% conversion rate, so if a CPU consumes 120 watts, there are 12-24 watts of heat generated on these three things. MOS tubes are the smallest in size and are the most prone to heat accumulation, followed by capacitance. The inductor builds up heat to the point that it doesn't matter, after all, it's just a piece of metal.

The MOS burns when it has too much heat.

Not necessarily, some motherboards have as long capacitance as the motherboard.

Generally, it is not easy, it should be that the electrolytic capacitor is easy to break, and if it is a tank capacitor, it is not easy to break.

This is not necessarily, generally the design of the motherboard is not good, the quality of the capacitor is problematic and the AC ripple component of the power supply is too large.

The ones that usually break are second- or third-wire motherboards. This is generally not the case in the first line. The first-line ones are MSI, Asus, and Gigabyte. If you don't understand, it's better to choose the first line.

It's just a matter of quality, and things that are not of good quality always break fast!

It depends on the workmanship and brand of your motherboard.

What should I do if the motherboard capacitor is broken. Generally, if the capacitor is broken, there will be capacitor explosion, slurry leakage and other phenomena. See it at a glance. Professional multimeters are also available.

To detect the test voltage, the first thing to do is to power on the motherboard, which is generally done by professionals.

If the capacitor is broken, you can use a soldering iron (or not live) to remove the broken capacitor and replace it with a capacitor of the same capacity or larger than the original capacity. Pay attention to the welding on both sides to prevent the occurrence of virtual welding.

If you don't have this technology, you should go to a professional maintenance person. The easiest way to remove the broken capacitor and replace it with the same capacity is to do this.

You can find a professional to replace the capacitor, if you have a strong ability to do it yourself, you can also buy the corresponding model of capacitor to replace it, but my personal suggestion is to let the professional replace it as much as possible, the risk of replacing it yourself is too great, and it will directly damage the motherboard.

Test whether the motherboard can light up, and if it can light up, change to a capacitor of the same capacity.

Change to a capacitor with the same withstand voltage value and the same capacitance.

If you have the technology, you can replace it, and if you don't have it, you can find a computer maintenance personnel to replace it, and don't cause a bigger problem because of a capacitor, otherwise the gains outweigh the losses.

According to your description, if it is confirmed that the capacitor is broken, after finding out the cause of the fault and eliminating other faults, then the capacitor of the same specification and model should be replaced. Thank you for your understanding and support!

Some of the capacitors on the motherboard are broken, but they can still be used normally; Some can be used but are unstable; Some capacitors are broken, and the motherboard is unusable. The first two cases will eventually become the last case if they are not used for a long time. Therefore, once you find that the capacitor of the motherboard is broken, the safest way is to replace the capacitor of the same model in time.

The capacitors on the motherboard are also called electrolytic capacitors.

Most of them are used as power filters. Its shell is marked with its capacity and withstand voltage, such as 3000 microfar, 50 volts, etc.

1. The motherboard capacitor will cause the computer to restart automatically for no reason, and it will take many restarts to turn on, and suddenly the blue screen will fail; In severe cases, it may cause damage to the CPU or Southbridge chip.

2. The function of the capacitor is to filter, which can turn the pulsating DC into an approximate straight line DC, high temperature is the main reason for the capacitor to burst, the power consumption of the computer or CPU is high for a long time, the capacitor of the CPU power supply part is easy to produce high temperature, resulting in the electrolyte inside the capacitor boiling, the pressure rises, when the pressure exceeds the pressure of the aluminum shell of the electrolytic capacitor, it finally exceeds the bearing limit of the capacitor top vent and bursts. Therefore, most motherboards no longer use electrolytic capacitors for CPU power supply.

3. If the capacitor on the motherboard bursts, it must be replaced with a capacitor with the same parameters as the damaged capacitor, and all the capacitors connected in parallel in the circuit should be replaced together.

Capacitors, often referred to as capacitors, are denoted by the letter C. Definition 1: A capacitor, as the name suggests, is a 'container for electricity' and is a device that holds an electric charge.

Product Name: capacitor. Capacitors are one of the electronic components widely used in electronic devices, which are widely used in circuits such as DC blocking, coupling, bypass, filtering, tuning loop, energy conversion, control, etc.

Definition 2: A capacitor, any two conductors (including wires) that are insulated from each other and in close proximity to each other form a capacitor.

Capacitors are not the same as capacitors. Capacitance is a fundamental physical quantity, symbol c, and the unit is f (farad).

The general formula c=q u parallel plate capacitor is the special formula: the inter-plate electric field strength e=u d, and the capacitance determination of the capacitor c= s 4 kd

With the rapid development of electronic information technology, the upgrading speed of digital electronic products is getting faster and faster, and the production and sales of consumer electronic products based on flat-panel TVs (LCD and PDP), notebook computers, digital cameras and other products continue to grow, driving the growth of the capacitor industry.

The lifespan has reached its limit.

At this time, the electrical performance of the entire circuit will be seriously affected.

Here's why. The large capacitor on the motherboard is mainly responsible for current purification, that is, filtering, when the capacitor is used for a certain limit, the capacity of the capacitor will become smaller due to the change of the chemical composition inside the capacitor, and the overall performance of the capacitor will decrease, at this time, the result is that the filtering ability of the capacitor itself decreases, and the heat generated by the equivalent resistance and ripple current of the filter capacitor will increase accordingly, and the ripple current and the heat of the capacitor will react on the capacitor itself, shortening the life of the capacitor.

Therefore, if the capacitor bursts or drums, it means that the capacitor is about to hang up, if the visual effect is very obvious (you can see it at a glance), then it means that the problem is more serious, it is strongly recommended to buy a new capacitor with the same label for replacement, otherwise it will seriously affect the use of such and such an inexplicable failure. The motherboard hangs up. And it will also hurt other peripheral accessories...

It is recommended that lz think twice...

What do you mean by not cultivating, do you mean continuing to use it?

The capacitors are burned, can they still operate normally, won't they crash frequently, and if the capacitor is broken, the motherboard is broken, and how to call it It's not much money to change a capacitor.

If it is not repaired, it will cause the motherboard to be unstable, easy to crash, blue screen, and unstable voltage. Capacitors are generally filtered.

You have to repair it, otherwise the stability is not good.

Also, this kind of problem is usually caused by overheating, and you have to solve the heat problem.

It's very simple, just buy a few capacitors and solder them.
