A power supply unit (PSU) is a critical component in any computer system, responsible for converting electrical power from an outlet into usable power for the internal components of the computer.
It ensures that the right amount of voltage is delivered to each component, protecting them from power surges and ensuring efficient operation.
The Functionality Of Power Supply
A PSU converts AC (alternating current) from your home or office into DC (direct current) which is used by computer components.
It also regulates voltage to prevent over-voltage or under-voltage conditions. The primary role of a PSU is to provide a stable and continuous power supply to all parts of the computer, including the motherboard, CPU, GPU, storage devices, and peripherals.
Components Of A Motherboard
A motherboard is the main printed circuit board (PCB) in a computer and contains essential components and connectors. Key components include:
- CPU Socket: Holds the central processing unit.
- RAM Slots: Hold the memory modules.
- Chipset: Manages data flow between the processor, memory, and peripherals.
- BIOS/UEFI: Firmware that initializes hardware during the boot process.
- Expansion Slots: PCIe slots for additional cards such as graphics or sound cards.
- Power Connectors: Provide power from the PSU to the motherboard.
Potential Risks To Motherboard From Power Supply
