Power pack 850 watts – the most important things at a glance

Power supplies play an important role in powering computers. They convert alternating current into direct current and thus ensure that the individual components of the computer are supplied with the correct voltages. Choosing the right power supply is important to optimize computer performance and ensure smooth operation.

A power supply with 850 watts Performance is a medium power supply and offers enough power for most computer setups. 850 watts are usually sufficient to operate a gaming PC or a video editor with a powerful graphics card and some additional devices such as hard drives or SSDs.

Most 850 watt power supplies are fully modular, which means they have a cable management system. This allows you to only use the cables you actually need, which greatly simplifies installation and makes the inside of your PC look cleaner and tidier.

Another important point when choosing a power supply is efficiency. You want to choose a high efficiency power supply as this means it uses less power which in turn can lower your electricity bills and help the environment. 87% efficiency is the minimum you should expect from a power supply of this class.

The best power supplies in the 850 watt class include the Corsair RM850x, the Seasonic Prime 850W and the Be Quiet! Straight Power 11 850W. All three are fully modular, offer high efficiency and have excellent reviews from independent test labs such as Tom's Hardware and AnandTech.

A power supply with 850 watts is a good choice for a powerful gaming PC or video editor. When choosing, pay attention to a fully modular power supply with high efficiency.
