Every computer needs a power supply. In many ways they can seem one of the most boring components in a computer. But should they fail or make too much noise, you won’t be a very happy user. We’ll look at some good options should you need a new PSU for an existing computer or a new build. There will be Amazon links included to purchase the PSUs and I earn a small commission if you use those links. Nothing else was provided for writing this.

One of the first considerations in choosing a power supply is the amount of power you need. In general, more high-end components can require more power. Specifically a high-end graphics card can requires enormous amounts of power. Today we’re going to look at the be quiet! Straight Power 11 series which comes with varying amounts of power.

While a power supply is typically out of sight, you also want it to be quiet so you don’t have to listen to it all day. Thanks to the fan’s blade design, fluid-dynamic bearing and 6-pole fan motor; you’ll find this a virtually silent power supply. Even though the fan is quiet, it still provides great cooling thanks to its funnel-shaped fan opening. One very powerful design feature is that the PSU is wire-free on the DC side. This extends the lifetime, better cooling and less signal disturbance.

One problem of some power supplies is that a number of cables that aren’t needed are still attached. This provides a rat’s nest inside your case. Each cable of the be quiet PSU can be removed if not needed. Not having those extra cables not only looks better, but helps keep your airflow smooth. This series is “Gold” efficiency certified which reaches up to 93% of the total power. Once again this helps keep your system cooler and quieter.
