We have products in the range "Atx Power Supplies" compared with each other and put together recommendations for you. Here you will find the top 15 in the “ATX power supply” section.

Atx power supply – the most important things at a glance

An ATX power supply is a special power supply designed for computers. There are different types of ATX power supplies, but they all share some common characteristics. For example, most ATX power supplies have a 5-pin connector for the motherboard and a 4-pin connector for the CPU. Other common features are a 3,3V output and a 12V output.

Most ATX power supplies also have a 24-pin motherboard connector. This connector is typically used on the newer versions of motherboards. Some of the newer models of ATX power supplies also have an XNUMX-pin CPU connector. This is required for the newer models of CPUs. Most power supplies that use this Connection will also have a four-pin for the mainboard connection. These two power adapters are different, but they are both required for use with a computer.

Many of the power supplies on the market today are modular. This means that the individual components of the power supply are detachable and interchangeable. This is a great benefit as it allows you to expand the power supply for future additions or upgrades. So when you buy a power supply, make sure it's modular.

Some of the other features that you can find in a power adapter are an Ethernet port, an HDMI port, a DVI port, and a DisplayPort port. These connectors allow your computer to be connected to other devices such as computer-based VCRs, televisions, or monitors. There are also power supplies that have a built-in fan. This is another great benefit as it allows you to ensure that your computer stays cool even under heavy use.

There are different types of ATX power supplies on the market. Most PSUs you will find are ATX v2.2 or later. These power supplies are best suited for computers that have high power consumption. The newer models of these power supplies tend to be more efficient and therefore take more load off the computer. Some of the newer features you can find in a power supply are a PWM fan, active PFC, and better cooling.

When you buy a power adapter, make sure it has all the connectors you need. Many power supplies also have a number of additional functions. For example, some power supplies have an LED indicator that shows you the operational status of the power supply
