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.
