The power cord is a wire that transmits current.Generally, the method of transmitting is the point -to -point transmission.The power cord can be divided into AC AC power cables and DC DC power cord according to the purpose. Generally, the AC power cord is a wire that is passed through a higher voltage AC electricity. This type of wire can be officially produced by a safe certification party due to high voltage standards.The DC line is basically through the low -voltage DC electricity, so there is no strict AC line requirements on security requirements, but the safety reasons are still required to uniform security certification.
Power line color
Usually: yellow: ground line black: zero -line red: fire line yellow+12VCPU, graphics card power supply; power supply for standard drive circuits, such as optical drive and hard disk motor orange+3.3V nowThere are other purposes of purple+5V (USB) USB device power supply, supporting the boot function of the USB keyboard mouse (still power supply after shutdown) the black ground line (0V) power supply circuit necessary part of the green PS-ON boot signal line (when it and the sameThe power supply will start the power supply)
Power line price
The price of desktop computer host power cord: Due to the different uses of the power cord, the models are different, and the price is different. The power cords generally used by computer hosts are according to international standards, which can be universal, but the computer can be used, but the computer can be used, but the computer can be used, but the computer canThe host electrical line is divided into two types. One is the power cord of curved insertion. The model of the computer host of the Samsawa brand is DY-03, the price of Jingdong website is 15.9 yuan, and its length is 1.8 meters. The computer is the computer.The JD.com website with direct insertion of the host electricity line is 16.8 yuan. Basically, no matter what brand it is, the price is floating between 15 yuan and 17 yuan. There is not much change, and the price is relatively stable.

Power cord connection method
1. The power cords we usually see in daily life are wrapped around each other. In physics, the number of turns determines the current strength of the power line.The power cords that are wrapped in each other can ensure that there is no short -circuit and burning phenomenon.This is the common sense of everyone who has learned physics and electricians.2. In addition to the connection method of a circle of wound, there is other connection method of the power cord, that is, the main parts of the power line are overlapped, and the number of turns of 6-8 are wrapped.The problem, the operation method is simple and safe. If you want to connect the wire, you can use this thickened method.3. In order to prevent the conductivity and accidents of the power cord, we usually wrap some electrical tape with an electrical resistance in the place where the power cord is connected to reduce the resistance of the current, prevent electric shock, and also have a fire prevention effect.
