Model overview based on user reviews
The "be quiet! Pure Power 12 M" power supply unit is praised for its modular wiring system, silence, and reliability, making it a popular choice among users. It offers a long-term warranty and is noted for its quiet operation and efficient performance with up to 92.6% FCC. However, some users have experienced issues with stiff cables that are difficult to connect, particularly the 24-pin plug, which may be a concern for those with larger cases. Additionally, there was a report of a unit arriving with a broken seal, affecting the warranty. Despite these concerns, it is considered a good model for its price, especially for smaller builds, and is recommended for its silent operation and modular design.

I took a 650W for a system with R5 5600 + RTX 4060. Installed it without problems, except for the very tight fit of all the cables, especially the largest 24 pin (visible in the photo). I was pushing with all my strength, the board and the case were bending)) I was already thinking it might crack, went to a specialist, and he said, "Well, what do you expect, it's new," but a friend recently built a PC with a PSU from Gigabyte and all the cables plugged in easily. I saw reviews that some people didn't have enough cable length, but my case is mATX format, and I didn't experience this issue, maybe it's from users with ATX boards and consequently larger cases. Otherwise, I have no complaints about the PSU, it's been working for a little over 2 months without issues. Long-term warranty Quiet Reliable Modular If you have a large case for full-sized ATX boards, the length of the native wires might not be sufficient. Be careful. The 24-pin plug inserts very tightly, but this might be a motherboard issue.  Sergiy: use be quiet! BN342 few months |
I recommend it as a good model! Silence in the robot 93% FCC (up to 92.6% FCC), modular design, important, subtle components in the middle. The next day, the screen is like a bi showing the speed of the PC at a given moment.  PHOTO-PR: use be quiet! BN343 few months |
The Pure Power 12 M power supply suddenly disappeared from be quiet!’s site, like it was never there. Kinda sad... Got a bad feeling. but while it's doing it, it's actually quiet. Everyone is satisfied. Slava Detyshev: use be quiet! BN341 few months |

Quiet brand policy
The be quiet! Pure Power 12 M BN341 power supply is characterized by a high efficiency level of 93% and is certified by the 80+ Gold standard, which confirms its reliability and energy efficiency. The manufacturer offers a 10-year warranty, eliminating any doubts about the device's durability. The brand's primary priority is noise minimization, achieved through a well-thought-out temperature control system: automatic fan speed regulation, additional radiators, and components with low heat emission. As a result, the unit does not require powerful cooling, and the optimized 120mm fan maintains a noise level of just 8 dB under average load.
Modern power system
The model is aimed at high-performance PCs designed for professional gaming and executing any resource-intensive tasks. A separate 16 PIN line (12VHPWR) supports the connection of top-tier graphics cards of the PCIe 5.1 standard with a power consumption of up to 300W. The +12V line can handle loads up to 550W, and two PCIe 8 PIN connectors (6+2) ensure compatibility with all graphics adapters. The power circuit implements a MOSFET cascade, LLC, and DC-DC conversion, guaranteeing stable and clean output voltage. The unit can withstand short-term power peaks of up to 600W without shutting down. Stability is monitored by a comprehensive protection system (OTP, OCP, UVP, SIP, OVP, OPP, SCP), and a built-in controller tracks input and output parameters to prevent failures. A thoughtful modular cable design significantly simplifies PC assembly and allows for efficient cable management. Thin and flexible cables are easily concealed in the case's compartments, ensuring a neat external appearance.
