What is a computer power supply unit (PSU)?
A computer power supply unit (PSU) bridges an external power source and a computer’s internal components. It converts high-voltage alternating current (AC) from a wall outlet into low-voltage direct current (DC), which components such as the motherboard, CPU, graphics card, and storage drives require.
What is a PC & PSU?
A PC or PSU converts electrical power from an external source into a usable form for the computer’s internal components. It transforms alternating current (AC) from a wall outlet into direct current (DC), which is required for the motherboard, processor, graphics card, storage drives, and other peripherals.
How does a power supply work?
In the context of computers, a PSU converts alternating current (AC) into direct current (DC) and distributes it to the various internal components like the motherboard, CPU, and storage drives. This conversion process is critical because most electronic components cannot operate directly on AC power.
Why does a PSU need a constant power supply?
Additionally, just as the heart needs to pump blood at a consistent rate and pressure, the PSU must provide a constant and stable power supply to the computer components. Any fluctuations or interruptions in the power supply can cause the computer to malfunction or can even damage the component. Where is the PSU on a computer?
What are the different types of PC power supplies?
Computer power supplies come in various form factors, each designed to fit specific PC case sizes and requirements: The ATX (Advanced Technology eXtended) power supply is the standard PSU form factor for most desktop PCs. It typically measures 150mm wide, 86mm high, and 140mm to 180mm deep, following Intel’s ATX standard.
What is PSU wattage?
Wattage Wattage indicates the total power the PSU can supply to your system. It’s essential to calculate the power requirements of your components and choose a PSU with a wattage slightly above your needs. For instance, a gaming PC with a high-performance GPU and CPU may require a 750W or higher PSU, while an office PC might only need 400W.
