Model overview based on user reviews
The "be quiet! Pure Power 11" series is highly regarded for its quiet operation and gold certification, offering good efficiency under load with multiple protection systems and stabilization. Users appreciate its high-quality construction and design, developed in Germany, and backed by a 5-year warranty. The PSU remains quiet even at peak loads, making it an attractive choice for those prioritizing silence. However, some users noted that it can overheat slightly during extended heavy gaming sessions, which seems to be a trade-off between silence and cooling efficiency. While most reviews are positive, one user reported issues with fan squeaking after a year, indicating potential quality inconsistencies. Overall, it is recommended for its performance and reliability, though the equipment included is somewhat sparse.

Very high quality block. High-quality both in layout and assembly, and in the selection of elements and functionality. A very quiet cooler, which actually was the main factor in the advantage of the purchase. It doesn't make noise even at peak. According to the declared characteristics, the block has a certificate of 80+ gold, I did not check it, but I think everything + - it is, because in tests and reviews they measured it despite an error of + -3%, everything is the same (with a load of more than 50%). Collected in a block with NZXT, bottom location. The block does not get very hot, but it certainly radiates heat. My hands itched to take it apart and look at the layout itself and the conders, but it is under warranty. According to what I dug up, there is no varistor, but a stomt arrester, the diode bridge is cooled by a radiator, there is a fsp, tyap conders. The block heats up to 50-55 degrees in normal load, and in high load 60-65 degrees (measured personally), which is normal for me. Good efficiency under load. Many protection systems and there is stabilization. High-quality platform of conders, bridges, etc. Quiet even at peak load. The operating temperature is normal, but sometimes it overheats a little. Apparently a compromise between silence and efficient cooling. But this happens if you play heavy games for a long time.  Anton Ch: use be quiet! BN294 few months |
It's just van love bp, it doesn't get any better than this. Design Fan (27 decibels) Gold certification Developed in Germany Warranty (5 years) The equipment is rather sparse  Nikita: use be quiet! BN293 few months |
