电脑电源线颜色详解(Computer power line color detail) Power line color detail When it comes to power line color, computer enthusiasts know: for example, some green boot line, black ground, the green line and black line short circuit, the power will start to work, try to supply power for the equipment, which is a simple method to judge the power, and yellow represents a 12V power supply, 5V power supply, but on behalf of the red. The working principle of color and other more details of these lines you understand? A detailed understanding of these will help you more in-depth understanding of computer and computer maintenance and fault resolution, the following do some detailed understanding, especially on the purple line, make in-depth explanation of green and gray line and boot principle. Yellow: 12V Yellow line in the power should be a large number of, with the addition of CPU and PCI-E graphics card power supply components, +12V role in the power of the pivotal. +12V has been providing power for spindle drive motors and track motors for hard drives, optical drives, floppy drives, and circuitry logic signals for operating voltage and serial port devices for ISA slots. When the voltage output of +12V is abnormal, the performance of hard disk drive, floppy disk drive and floppy disk drive is unstable. When the voltage is low, performance for the CD-ROM pick dish serious logical bad sectors hard disk increases, often bad sectors, the system is easy to crash, not normal use. On the high side, the drive speed is too high, prone to runaway phenomenon, more likely to explode disk phenomenon, the hard disk performance as stall, fly. At present, if the +12V power shortage, will directly affect the performance of PCI-E graphics cards, and affect the CPU, directly causing crashes. Blue: 12V The voltage of -12V is to provide logic level to the serial port, to the current is small, generally less than 1A, even if the voltage deviation is too large, it will not cause trouble, because the l
