Hi.
Using a BeQuiet! BQT P5 470W I was first shocked to see a BQT PSU failing in THG´s test, until I noticed it was the old B5 not the new P5.
Well the current Be Quiet PSU´s are in my opinion and experience safe buy´s. These things are incredibly stable and reliable. (at least mine is
And it was one of the first PSU´s which really was ATX 2.0 standard. Here are a few reviews, in german, sorry for that

For some reason I couldn´t find english reviews on it.

Be Quiet is also one of those manufacturers who listen to their customers and are really getting better and better. I expect some badass PSU´s coming from them in the future.
