be quiet! continues to improve/release new power supplies, adding all the latest technologies and improvements to its products. The recently released Pure Power 13M series includes a new design that improves overall power efficiency compared with the previous Pure Power 12M (94.3% vs 92.8%) and at the same time keeps all the good stuff, like the support for the ATX 3.1 and PCIe 5.1 compatibility. There is also a semi-passive cooling system that ensures virtually silent operation during low to medium loads and remarkably quiet active cooling under higher loads, and modular cables for a clean installation. This future-proof power supply is available in five wattages: 1000W, 850W, 750W, 650W, and 550W, each with 80 PLUS® Gold and Cybernetics Gold certification.

ATX stands for Advanced Technology Extended and is a design guide that includes specifications for PC cases, power supply units, motherboards, and more. Intel has published this guide since 1996. Version 3.0 of the PSU guide was released in February 2022 and describes the requirements for power supplies to meet the new specifications defined by PCI Express 5.0. This was the first major update in many years. The latest version, 3.1, was released in September 2023 and implements several fixes and refinements to the specification.

The main reason for the update from 3.0 to 3.1 is the new connector design, which makes it much safer to use. Some 12VHPWR connectors tended to become partially dislodged from the GPU or PSU power socket. In some cases, this resulted in uneven load distribution across the current-carrying pins and higher-than-expected heat. The newly introduced connector is called 12V-2x6 and is marked with “H++” on the side of the connector. The notable improvement is that its sense pins are shorter, which helps to disconnect the power when the connection comes loose. At the same time, the 12 conductor terminals are slightly longer, reducing the risk of losing connection. The new connector is 100% compatible with the old terminals. The new version also includes several minor changes related to test methodology, hold-up times, and clarifications. The most significant one, however, is the updated 12V2x6 connector.

Gold-rated efficiency with semi-passive cooling

Thanks to a proven combination of LLC, SR, and DC/DC topology, Pure Power 13 M delivers exceptional stability and voltage regulation. Certified with both 80 PLUS® Gold and Cybenetics Gold, it achieves high efficiency levels while maintaining low power consumption. A newly introduced semi-passive cooling mode allows the 120mm be quiet! fan to remain off under low and moderate loads, ensuring a virtually inaudible operation when full cooling isn’t necessary. When active, its airflow-optimized blades and temperature-controlled curve maintain the company’s hallmark quiet performance.

Designed for next-gen hardware

Pure Power 13 M fully supports Intel’s ATX 3.1 specification and is PCIe 5.1 ready, featuring a 12V-2x6 connector delivering up to 600W1 for the most demanding graphics cards, alongside up to four traditional PCIe 6+2 connectors2. The stricter safety standards of ATX 3.1 ensure improved support for next-gen GPUs. This makes it a highly compatible solution for both current high-end setups and future upgrades.

Improved design and functionality

Pure Power 13 M features a single 12V rail for stronger, more consistent power delivery and includes fully modular cable management, making cable routing easier and reducing clutter inside the chassis. The PSU is housed in a sturdy steel enclosure and continues to reflect be quiet!’s high standards in design and manufacturing, with quality assurance conducted in Germany. All models are backed by a 10-year manufacturer’s warranty, reinforcing be quiet!’s commitment to reliability and customer satisfaction.

80 PLUS® GOLD CERTIFIED

Pure Power 13 M 750W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 94.3%.  The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 13 M 750W is always the correct choice for quiet systems and gaming PCs!

FUTURE-PROOF YOUR SYSTEM

Pure Power 13 M 750W is an ATX 3.1 PSU and comes with both native integration of the 12V-2x6 connector for next-generation PCIe 5.1 graphics cards, and 4 PCIe 6+2-pin connectors for support of current-gen GPUs. This makes the PSU extremely versatile and the perfect choice for powerful systems of today and the ones to come.

THE NEW STANDARD OF POWER

Pure Power 13 M offers 750W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time: Pure Power 13 M 750W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.

SEMI-PASSIVE ZERO-RPM COOLING

While under low load, the fan turns off completely until its services are needed again for more demanding operations. This feature, combined with the reliable be quiet! fan and its airflow-optimized fan blades, make Pure Power 13 M 750W exceptionally silent in all load scenarios.
