Do computers run on AC or DC power?
The power supply converts the alternating current (AC) line from your home to the direct current (DC) needed by the personal computer. Power supplies, often referred to as "switching power supplies", use switcher technology to convert the AC input to lower DC voltages.
A power supply unit (or PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.
- (Advanced Technology EXtended motherboard) The PC motherboard that superseded the Baby AT design. The ATX layout rotated the CPU and memory 90 degrees, allowing full-length expansions to be plugged into all sockets. The power supply blows air over the CPU rather than pulling air through the chassis.
- A computer's microprocessor is usually busy with other work, so the graphics card handles this. The card has a chip called a Graphics Processor Unit, a microprocessor specialized for video calculations. The GPU lets the computer's main processor do its job, allowing the computer to run at full speed.
- Dimensions of a full-size ATX board are 12 × 9.6 in (305 × 244 mm), which allows many ATX chassis to also accept microATX boards. The official ATX specifications were released by Intel in 1995 and have been revised numerous times since. The most recent ATX motherboard specification is version 2.2.
