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 |
A good unit, but it was defective. A year later, it was sent under warranty due to "rattling." They replaced it (telemart). Silence, cables, functionality performed "Noise", what happened to him in the end - I didn't even ask Anuxi: use be quiet! BN345 more than year |
