Putting it to the Test

The Straight Power 11 PSU has a fairly simple setup process very similar to other PSUs on the market. It comes with all of the necessary cables to start getting power to other components of your computer. The packaging comes with zip-ties to get your wires neatly into your case as there are many cables to plug up. Overall, it took around 30-40 minutes to fully install this power supply into my already built PC. This includes taking out my old PSU. If you are looking to upgrade to a new power supply, then the Straight Power PSU will make it super simple to set up and plugin to your computer. After plugging it into my PC, everything was running perfectly fine. 


Going Wireless

One of the newest features in the Straight Power !! PSU is the wire-free design on the inside of the actual PSU itself. (Note: if you do take apart the PSU, you will void any warranty on the product). This makes the inside of the PSU seem very clean and neat, which comes across as great quality control from be quiet! As stated on the be quiet! Website the wireless design “The Straight Power 11 650W is wire-free on the DC side inside the PSU body. This results in improved cooling airflow and less signal disturbance, simply because of a lack of wiring, and ultimately pushes the lifetimes of the components to a maximum.”


How Quiet is Be Quiet?

With every be quiet! product there is always the question of just how quiet is it? In my experience with Straight Power 11, it is substantially quieter than my old PSU. This is likely due to the Silent Wings 3 fan that has been put inside the PSU. This knocks out any remaining white noise that may have been coming from the PSU and is one of the first PSU I’ve seen on the market to eliminate electrical noise as the Straight Power 11 does. This, along with the wire-free design and optimized airflow, the Straight Power 11 can barely be heard, and you really have to isolate it to hear anything coming from it. In all, when this thing is on your PC, you will likely forget you have it installed due to how silent it really is!


Overall the Straight Power 11 is a great power supply and gets the job done. There are several different models available, so if you want more power, you have the option of upgrading. If you are in the market for a new PSU or are simply building your first PC, I would highly recommend going with be quiets! Straight power 11 as your PSU. I would also recommend looking more into be quiet! in general, as they are making great strides to become more relevant in the PC Hardware scene outside of Germany. Great job be quiet!
