PC power supply Atx – the most important things at a glance

Now that you are interested in an ATX power supply for your PC, you should first know what it is and what versions there are. ATX is an acronym for Advanced Technology eXtended and refers to a form factor design for computer motherboards developed by Intel in 1995. The current version of the standard is the ATX 2.2, released in 2004. There is also an older version of the standard, the ATX 2.01, released in 2000. Many motherboards and power supplies on the market still use the older ATX 2.01 specification, but it is possible to find power supplies that support the newer ATX 2.2 standard as well.

If you are looking for a power supply, you should definitely pay attention to which standard it supports. However, the differences between the two standards are relatively minor, and most power supplies you find will likely support both standards.

There are two main differences between the two standards. On the one hand, the current version of the ATX standard, the ATX 2.2, is compatible with a higher voltage. On the other hand, the newer version of the standard also supports a number of extensions that could be made in the future. These include, for example, an expansion of the power supply connection to 24-pin instead of 20-pin and support for higher voltages of up to 25 Volt.

Many of the power supplies you find on the market support both the old ATX 2.01 specification and the newer ATX 2.2 specification. However, there are a few manufacturers who have made power supplies specifically for the newer specification. These power supplies tend to be a bit more expensive, but they also have some additional features.

Most PSUs you can find will support either the old ATX 2.01 or the newer ATX 2.2 specification. So it is important that you choose a power supply that best suits your needs. For example, if you plan to install a new processor or graphics card in the future, you should consider whether you need a power supply that supports higher voltages.

Another important factor when choosing a power supply is the Performance. Most power supplies you can find will be able to power your PC, but it's important that you choose a power supply that offers enough power for your needs. For example, if you want to install a powerful processor or a new graphics card, do so
