CUSTOMER CASE
At present, with the continuous popularization of the Internet, its basic equipment computer has also become a must-have product for family life. Many people will see various assembled power cords before assembling a computer, and the colors of these power cords are also different, yellow, white, blue, and purple. Among the many colors, purple is a more conspicuous color, so what does it mean?
The purple power cord represents +5VSB (+5V standby power). It is very different from other power cords, that is, it can provide power for the computer when the computer is in standby. As long as the general power cord is not working, these power cords are in a non-working state. Of course, the computer not working here means that the computer is in standby or off state, not when the computer is turned on and not working.
In addition to the normal switch of the computer, there are options such as sleep and standby. As long as these options are selected, the computer’s power cord is only working in purple, which can maintain the computer in a standby state through the power supply. This is the so-called standby power supply, which is WOL (Wake-up On Lan) and boot circuit, USB interface Wait for the circuit to provide power.
Generally, the role of the purple power cord in the boot circuit is divided into two ways. One way the power leads to the power switch on the chassis is usually in a different state; the other way is to lead the power to the south bridge chip on the motherboard, this is the most common way of working.
Only by knowing the working conditions of the purple power cord in detail, then we can know its usage, and thus know its role in the entire computer.
