ATX Power supply form factor

ATX Power SupplyATX stands for “Advanced Technology Extended“. This is the standardization of the latest computer packages. All computer components, which are also standardized to ATX can be installed in this housing. ATX power supplies support the latest additional features that bring any modern computer with it. The different types of PC power supplies differ mainly due to equipment size and the number of available slots and ports. To meet the ATX standard power supply, it should at least provide a voltage of two 12 volt-rails, and a +5 volt, 3.3 volt, 12 volt rail and a standby power.

ATX power supply units provide various advantages compared to its predecessors AT format. The I / O connections are now integrated and the power connector on the motherboard is also polarized. There is a voltage control, no outgoing voltage from the power cable any more, which leads through the computer case.

However the I / O components is defective, they can not be easily replaced because they are on the motherboard. Also, the computer consumes electricity even in standby mode. To turn off completely, it can be done through the main switch.

Many modern PC power supplies in ATX format are now able to work with different electrical networks. Some must be activated manually, but this is dangerous, if wrong in doing this the PC power supply will be damaged forever. Another device can automatically adjust, and allow the AC voltage from 100 volts to 240 volts.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
