Powerful, modern and relatively inexpensive by be quiet! computer power supply standard ATX 3.0. This factor guarantees the device’s ability to provide power to modern video cards with a 12VHPWR connector and peak power consumption of up to 600 W without any adapters. This PSU belongs to the middle price range and is part of the Pure Power line, the products of which are distinguished by high quality workmanship and extremely low noise levels.
It features a 120mm fan that automatically changes speed based on device temperature, and airflow-optimized fan blades that reduce turbulence for quiet operation with efficient cooling. According to the manufacturer, at a peak load of 100%, the maximum noise level does not exceed 26 dB. The circuitry of the device uses advanced LLC topology and DC-DC converters of secondary channels, and the power supply itself is equipped with two +12V lines.
Heat-resistant capacitors, alas, are not Japanese, which may scare off particularly demanding users. At the same time, the manufacturer is so confident in the quality of its products that it positions this PSU as a power source that is undergoing at least one global component upgrade. Confidence is backed by a 10-year warranty. 93% efficiency is within the 80+ Gold standard and can easily withstand short-term loads up to 1000 W along the main +12V line, without noticeable voltage drops below the specified level. All wiring uses a modular connection system, so unused cable noodles can be disconnected and stored out of sight. Plus, be quiet! Pure Power 12 M is equipped with all kinds of protections, including overheating, overcurrent, short circuit, overvoltage and undervoltage.

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.  Sergіy: use be quiet! BN342 few months |
Good power supply, Ale came with a broken seal, it’s not acceptable, No guarantees now, I don’t recommend before buying Modular wiring system Broken seal Nubloїd 002: use be quiet! BN342 less than month |
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 |
