A powerful, modern, and comparatively affordable ATX 3.0 standard computer power supply by be quiet!. This ensures the device can provide power to modern graphics cards with a 12VHPWR connector and peak energy consumption up to 600 W without any adapters. This PSU is in the mid-price range and is part of the Pure Power lineup, known for its high build quality and extremely low noise levels.

The installed 120-mm fan automatically adjusts its speed based on the device's temperature, and the fan blades optimized for better airflow reduce turbulence, ensuring quiet operation with efficient cooling. According to the manufacturer, at peak 100% load, the maximum noise level does not exceed 26 dB. The unit's circuitry uses advanced LLC topology and DC-DC converters for secondary channels, and it's equipped with two +12V rails.

The capacitors, unfortunately, are not Japanese, which might deter particularly demanding users. Nevertheless, the manufacturer is confident in their product's quality, positioning this PSU as a power source that outlasts at least one major upgrade of components. This confidence is supported by a 10-year warranty. It has a 93% efficiency that fits the 80+ Gold standard and handles short-term loads up to 1000 W on the main +12V line without noticeable voltage drops below the allowable level. All wiring uses a modular connection system, allowing unused cables to be detached and tucked away. Additionally, the be quiet! Pure Power 12 M is equipped with all kinds of protection, including overheating, overcurrent, short circuit, overvoltage, and undervoltage.

Garniy choice for small buildings
25 December 2023 
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.

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.
