The computer is a relatively sophisticated instrument, and every part in it will play its due role to ensure the normal use of the computer. In the current computer, in addition to various parts, it is the power cord that is seven or eight. The number of these power cords is very large, and the colors are also different. Then let the relevant experts explain to us the meaning of each power cord.
Red indicates the +5V power cord, which is the working voltage of the chips on the computer motherboard, hard disk, optical drive and other hardware. Without the power cord, the corresponding functions of the computer cannot be turned on.
White represents the -5V power cord, which is the opposite of the meaning of red. Generally, the white power cord is mainly used for the phase-locked data separation circuit of the floppy drive.
Yellow is the symbol of the +12V power cord. It is the working voltage of the hard disk, optical drive and other hardware, which can provide normal power for them to work.
blue is the opposite of yellow, representing the -12V power cord. Generally, the blue power cord must work with the yellow power cord. The blue power cord provides EIA power to the serial port.
The orange power cord implies a +3.3V voltage value. It generally only supplies power to DIMM and AGP slots, and does not provide power to other components, so the number in a computer is very small.
The gray power cable is the P.G signal cable. It can calculate a power source for computer operation through a certain calculation method. If this value does not meet the requirements for operation, then the corresponding equipment needs to be replaced in time to make it a normal power value.
The purple power cable is a +5V StandBy cable, which can provide part of the power when the motherboard enters standby, so that it can quickly enter a new open state.
Green means the PS-ON signal line, which can indicate the switch signal line of the motherboard power supply, and the voltage that is not connected.
The last color power cord is black, which represents the ground wire of the system circuit.
As long as you have a deep understanding of the meaning of each power cord, then you can truly know its role.
