PC power supply - The 15 best products in comparison

Recommended products in the area "PC power supply"

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

PC power supply – the most important things at a glance

There are two main components of a PC power supply: the Power Supplies (PSU) and the power switch. The power supply converts the voltage of the mains electricity into the DC voltage required by the PC. The power switch is a switch that turns on and off AC power to the power supply.

PSUs come in different sizes and designs. Most desktop PCs use an ATX power supply, which provides the +12VDC power required by most motherboards. Laptop power supplies are smaller and lighter and typically provide +19VDC. The Performance of power supplies is given in watts (W). The laptop power supplies are usually weaker than those for desktop PCs.

The power switch is a switch that turns on and off AC power to the power supply. Power switches are located either on the motherboard (if present) or on the back of the PC. Most power switches have two positions: ON and OFF. However, some power switches have a third position called standby or deep sleep mode.

Most power supplies are maintenance free and have no moving parts. However, there are some power supplies that include a fan for cooling. The fans usually rotate slower during operation than under high loads. However, with some PSUs, the fan may run even at low loads.

When choosing a power adapter for your PC, you need to make sure it has enough power for your PC. The power required is usually specified in your PC's user manual. Power supplies vary in the type of voltage they deliver and the maximum power they can deliver. Most power supplies supply +12VDC. However, some power supplies also provide a +5V or +3V DC voltage.

The voltage that a power supply supplies is the DC voltage that is generated by the mains current. The maximum power that a power supply can deliver is specified in watts (W). Power supplies for desktop PCs are usually more powerful than those for laptops.

When choosing a power supply for your PC, you should also consider how many devices will be connected to the power supply. Most power supplies have multiple connectors for different devices. The connectors are usually color-coded to facilitate proper connection.

The most common connections are:

24pin motherboard connector

4pin CPU connector
