PC Power Supplies

Computer power supplies are standardized according to the ATX format, created in 1995 by Intel as a standard arrangement of components in computer cases. At that time, it replaced the older standard AT format. In 2003, Intel tried to replace it with BTX, but manufacturers did not switch to that format and instead ATX was revised several times. The latest and current versions are ATX2.2, and smaller formats mATX and Mini ITX.

As the ATX format developed, there were also changes in power supply - ie, in the area of computer resources. Therefore, it is now using ATX power supply for computer assembly versions 2.0, 2.2, 2.3 and 2.4 which differ in the main power connector, which plugs into the motherboard. It is therefore necessary for you to match the selected source to a version compatible with the motherboard.

When deciding which power source to buy, it is important to know the overall performance specification (given in watts and must be sufficient for the computer system - eg. For desktop computers 350-400 W is sufficient), cooling type and the amount and variation of additional power connectors.
