2022 what are computer power cables called?

So that’s how I understand what are computer power cables called?

Now I want to turn it over to you: Through my article, you understand how to choose and what are the standards?

Do you have a different point of view with the electrical outlet? Or any other questions?

Let me know by leaving a quick comment below right now.

The computer power cord is the 220v AC power input to the computer host atx power supply; the computer power cord is an essential part of the computer. Its role is to connect the motherboard power supply and cpu power supply.

computer power cables Color Description

Red represents the +5v power cable (motherboard, hard drive, optical drive, and other hardware chip operating voltage).

Yellow: represents the +12v power cable (hard disk, optical drive, fan, and other hardware operating voltage, and -12v while providing eia power to the serial port).

Orange: represents the +3.3v power cable (direct power to the dimm, agp slot).

Gray: represents the p.g signal line (power status information line, it is the result of other power lines through a certain circuit calculation, when the computer after pressing the start button, this signal indicates that the power supply is good can be turned on no signal means there is a fault motherboard automatic monitoring).

Blue: represents the -12v power line (to the serial port to provide eia power)

White: represents the -5v power cable (floppy drive phase-locked data separation circuit)

Purple: represents the +5v standby power line (after shutdown to provide power to a small part of the circuitry of the mainboard to detect various boot commands)

Green: on behalf of ps-on signal line (motherboard power on/off signal line, not connected when there is a certain voltage, can be directly relative to the black line connected to a switch as a test, can also be seen as the boot key when the boot)

Black: the ground of the system circuit

computer power cables wiring instructions

computer power cables Reset switch: two-pin. This switch is connected to the plug and is generally marked with the word reset SW, and the corresponding position on the motherboard near the pins of the English abbreviation for reset, rest, rs or re, etc. Not divided into positive and negative, inserted in the opposite also effective.

computer power cables Power light: the connection is also a two-pin plug, one of the connections is generally expressed in green; the other connection is white. When the host power is activated, the power light will light up. This switch is generally marked with the word power led on the plug and the corresponding position on the motherboard pins near the English abbreviation for pw led, power led, pwr led, or pled+ and pled-, etc. The connection is reversed, not light, just change over.

computer power cables Hard drive light: hard drive light cable is also a two-pin plug; the two wires are generally red and white. When the hard disk has read and write action, the hard disk light will light up. This switch is generally marked with the word hdd led on the plug and the corresponding position on the motherboard pins near the English abbreviation for hdd led, hd or ide_led+ and ide_lde-etc. Connected to the reverse does not light up; it just changes over.

computer power cables Speaker: The plug of this connection has four pins but only two wires; its color is generally red and a black or an orange and a black, correctly connected for the use of the speakers on the chassis. This switch is connected to the plug, and the corresponding pins on the motherboard are generally marked with the word spoken.

Some computers will send out a “beep” through the speaker after a normal startup, or when it does not start normally, send out a corresponding alarm sound through the speaker to help users solve problems. However, some motherboards already have integrated speakers, so it is not necessary to connect the speakers on the case.
