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 |
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 |

Supports ATX 3.0 and PCI-E 5.0
be quiet! Pure Power 12 M is a modern power supply that combines excellent performance, energy efficiency and functionality, making it an ideal choice for a variety of users. The model is 80 Plus Gold certified with an efficiency of up to 93%. Pure Power 12 M also supports the PCI-E 5.0 standard and includes a 12VHPWR connector, which allows you to connect GeForce RTX 4000 graphics cards with a power consumption of up to 600 W without the need for adapters.
10 years warranty
To develop the power supply, the company chose an affordable but high-quality HEC platform with LLC topology, half-bridge converter and DC-DC converters for secondary lines. According to the manufacturer, it provides stable voltage with minimal deviations (less than 2%) and a significant power reserve (+25% of the nominal). The device uses solid Teapo capacitors and high-quality German transistors. Despite the absence of Japanese capacitors, which are often found in 80+ Gold class PSUs, a 10-year warranty and a wide range of protective functions confirm the high reliability of the power supply, which can easily withstand several system upgrades.
Quiet fan and modular cables
All power cables in the model are modular, which allows you to disconnect unnecessary cables when assembling the system, simplifying the process and maintaining order in the case. The Pure Wings 2 fan with a diameter of 120 mm with PWM control automatically adjusts the operating speed to ensure an optimal level of acoustic comfort. Even at maximum load, the noise level does not exceed 26 dB, which makes be quiet! Pure Power 12 M an excellent choice for those who value silence.
