basics
Ampere (A)
Electrical current is measured in ampere, which describes the movement of electrons in an electric circuit. The abbreviation for ampere is a capital A.
Auto Restart Function
The auto restart function refers to the ability for a fan to restart on its own without any damages following mechanical obstruction (such as being stopped by hand).
Air Pressure
When referring to PC fans, the air pressure is indicated in mm/H2O (see corresponding entry).
AMD
AMD® is an American microprocessor maker. The company was founded in 1969. Alongside computer CPUs, AMD also produces graphics chips and chips for communication solutions. In 2006 AMD acquired former graphics chip maker ATI Technology.
Air Flow
The air flow indicates how much air a fan can move per unit of time. Because the air being moved represents a volume, air flow is indicated in cubic meters per hour (m3/h), or CFM. Among other factors, air flow reflects the number of fan blades, their operating angle and rotational speed.
AC (Output)
The acronym stands for "Alternating Current". It refers to the fact that the electricity periodically switches its polarity in even portions. The most common form of AC is sinusoidal.
All In One Cable
Various power supply series are equipped with a cable bundle containing all drive connectors. Each cable bundle thus contains at least one Molex plug, one S-ATA plug and one floppy plug. The benefit is that only one single cable bundle need be installed to power all of the drives used in a computer.
