About :
The computer power supply unit is one of the most important parts in the system that receives electricity from the city power grid and converts it to suitable voltages for the internal parts of the computer. This device is responsible for providing stable and sufficient voltage so that parts such as motherboard, processor, graphics card and hard disk work properly. Common voltages in power wires: 1. +12V yellow: for high-use parts such as processor (CPU), graphics card (GPU), and fans. 2. Red +5V: for low consumption components such as storage drives and some chips. 3. Orange +3.3V: for some motherboard circuits and low-power chips. 4. -12V blue: mostly for old serial ports and special applications. 5. Purple +5VSB: to provide standby power that keeps the motherboard and certain devices active even when the system is off. 6. Ground (black): ground wire that is used to return electric current. These voltages are determined by ATX standards and the power supply must be able to produce them accurately and without fluctuations.
