Basic knowledge: the color of the power cable definition for PC

Power is the heart of the computer, Provide energy for the stability of the computer work. The power cable usual include: Yellow, red, orange, purple, blue, white, grey, green, black. nine kinds of color (some powers do not need white cable). So, what meaning are the colors ?
Yellow cable: +12V   It is for Hard drive, cd-rom, ISA slot or cpu etc.
Red cable: +5V  It is for CPU, PCI, AGP, PCI-E, ISA slot etc.
Orange cable: +3.3V   It is for memory.
Purple cable: +5VSB  It is on standby power supply.
Blue cable: -12V
White cable: -5V
Green cable: P-ON  It controls the power switch, when the port signal level is greater than 1.8V, the main power is off; when the port signal level is below 1.8V, the main power will work. If you make a short circuit between green cable and black cable, the power will work, if the power does not work, then it was damaged.
power signal cable.  Usaul it output greater than 2V, the power is good. if it output less than 1V, then the power is bad.
Black cable: GND

Power IC replacement for PC motherboard

I/O IC replacement for PC motherboard

I/O chip is easy to be damaged, too. We share some replaceable models.

Winbond I/O only distinguish the model number, and F=G.
W83627HF-AW == W83627HG-AW
