    It depends on what kind of wrong way it is.

    1. If the high voltage is connected to the low voltage, and it exceeds the withstand voltage value of the receiving circuit, it will definitely burn.

    2. If the power supply and ground are reversed, and the circuit does not have an anti-reverse plugging design (generally only the power input has this design), most of them will burn.

    3. If the power pin is connected to the signal pin, most of them will burn.

    4. The low voltage is connected to the high voltage input pin, and it will not burn normally.

    Does it mean that the motherboard is connected to the chassis signal cable? Generally, the 4 groups are power and hard disk indicators, as well as boot and restart. Carefully check the motherboard's instructions or printed logos when plugging in.

    If the power button of the case is connected to the LED indicator interface, it will only fail to send a boot signal, if it is connected to the restart interface, the boot button will become a restart function, which will not cause the motherboard to burn out, and the power button 2 wires do not distinguish between positive and negative poles.

    There are a few main ways to learn about computers.

    1: The computer is very important for beginners, and the teacher introduces the door, but in the future, it will depend on self-study. Self-learning ability is particularly important for computer learning, the reason is that the computer is developing rapidly, and only by mastering self-learning methods and having self-learning ability can we cope with the ever-changing development situation of computers.

    Some people say,"Self-learning is easier said than done! "I said that other subjects may be more difficult to learn on your own, but computers are relatively easy. Why?

    Because the computer is getting better"Approachable", so that people can see and touch. Things that can make people move are easy to learn, such as how old a doll dares to turn on the TV and adjust the channel, can control the VCD, etc., isn't the TV and VCD machine high-tech products? As the learning object, the theoretical knowledge and practical environment are unified, the learning content and progress can be mastered by oneself, and most of the things that cannot be understood in self-study can be solved by the computer.

    Therefore, I say that it is easy to learn on your own, easy to learn on your own. Of course, it would be better to have a guide book that is easy to study on your own.

    It's hard to say such a problem, but according to my experience, the motherboard may have been broken before, and as long as you replace the power supply in the past, it is good, and the motherboard should not be burned.

    Short circuit is generally not burned out of the motherboard, this thing because the circuit short circuit when the current does not pass through the electrical appliances, according to the situation you said, because the motherboard has a problem, your power supply green wire and black wire are connected to see if the power supply fan turns, if the turn is the power supply has no problem and does not turn, then the power supply is broken, you look for other reasons, the easiest way is to find a piece of the same motherboard to try, you know that the problem is **, good luck! (Hopefully you have the basic skills in this area, otherwise the problem will get bigger and bigger).

    Generally, it will not be plugged incorrectly, your motherboard may be broken before the power supply is replaced, or it may be that the motherboard is broken due to the connection of parts or static electricity when you change the power supply.

    I have also encountered this situation, which is generally caused by the aging of the motherboard and power supply, and it may be okay to plug and unplug it a few more times.

    If it is wrongly connected, it will be, because the output voltage on the same power supply is different, there are 5V 12V

    The question is how can you connect it wrong, the current power supply is designed with fool-proof interfaces.

    Switching power plugs and motherboard sockets.

    Poor contact will occur!

    But modern motherboards don't appear.

    Plug in the wrong "phenomenon, so you can't "burn" the motherboard!

    When you plug it in.

    It must be guaranteed to be in place!

    Their locking hooks must:

    You have to be locked down!

    You should mainly check 4 or 8p plugs!

    Since it is hardwired, it is most likely to be out of place!

    No, he can't plug in the different wires, see if the jumper of the motherboard is plugged in wrong.

    How to plug in the wrong power supply.

    There are two interfaces in total.

    No matter how you plug it in, you won't plug it incorrectly!

    It should be something else, isn't your power supply broken!

    The question is not. Show me options. I pressed 8 and it became like this. What is this question that answers the question that you are turning off and on again. When I got to the selected place to take a picture, I saw that in addition to 8, there are other options?

    Question: Now it's turned on like this.

    You probably have to restore the system for this problem.

    If you don't have a spark, it's probably fine, you unplug everything and check it all over again. Is it that the wire is not connected?

    The power supply fan does not rotate, and the power supply has no current?
