We have already reviewed the very good be quiet! PurePower 12M sereies at the 850Watt variant. be quiet! continue to improve their position at high power supplies and releases a new version that boosts up to 1200 watts of power with the PurePower 12M series supporting even the most demanding users at affordable price.

The be quiet! PurePower 12M series is certified 80 PLUS Gold, featuring high-class technology such as LLC topology and up to five PCIe connectors for both PCIe 5.0 GPUs and GPUs with PCIe 6+2 connectors. Additionally, Pure Power 12 M features fully modular cables for ease of installation. Pure Power 12 M includes full support for the ATX 3.0 standard, which observes the power specifications defined by PCI Express 5.0. Compared to ATX 2.X, which supports high load peaks but does not define a maximum above the nominal power of the power supply, ATX 3.0 defines clear target values – specifically, the PCIe connection for the graphics card must allow load changes of up to three times the power consumption.

Pure Power 12 M is designed to handle these extreme transient loads with ease. ATX 3.0 power supplies with 450 watts or more also require a new 12VHPWR connector, which is able to deliver significantly more power. Additionally, all Pure Power 12 M models also offer up to four ‘traditional’ PCIe 6+2 connectors for full graphics card compatibility. This makes the PSU extremely versatile and a perfect, future-proof choice for upcoming next-gen devices and current high-end systems alike.

Thanks to LLC technology, Pure Power 12 M offers advanced stability and voltage regulation. All models are certified 80 PLUS® Gold, with a high operating efficiency of up to 93.2%, and include a full suite of safety features. Two independent 12V rails provide up to 850 watts of continuous power. Pure Power 12 M integrates an exceptionally silent 120mm be quiet!-fan, which is temperature-controlled for the best balance between effective cooling and quietness. Airflow-optimized fan blades reduce turbulence, allowing for best-in-class quiet operation with excellent airflow. Pure Power 12 M includes fully modular cable management, to simplify component installation and reduce cable clutter in the chassis. With product conception, design, and quality control in Germany, all models receive a full 10-year manufacturer’s warranty.

The Pure Power 12M 1200Watt variant will cost 199.00 Euro.

80 PLUS® GOLD CERTIFIED

Pure Power 12 M 1200W is certified 80 PLUS Gold with an outstanding efficiency rating of up to 93.7%. The most compelling benefit: lower power consumption, consequently lower costs, and above all a cooler as well as quieter operation. Pure Power 12 M 1200W is always the correct choice for quiet systems and gaming PCs!

FUTURE-PROOF YOUR SYSTEM

Pure Power 12 M 1200W is an ATX 3.0 PSU and comes with both native integration of the 12VHPWR connector for next-generation PCIe 5.0 graphics cards, and 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 12 M offers 1200W of continuous power with 2 independent 12V rails. Even if the graphics card demands excessive power for a short time: Pure Power 12 M 1200W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.

UNPRECEDENTED SILENT OPERATION

The exceptionally silent 120mm be quiet! fan is temperature-controlled to strike the best balance between effective cooling and quietness. Airflow-optimized fan blades reduce turbulence, enabling best-in-class quiet functionality. 

HIGH-CLASS TECHNOLOGIES

With its LLC topology Pure Power 12 M 1200W provides a best-in-class voltage regulation and efficiency. That makes it perfect for building very quiet systems or upgrading gaming and media creation PCs.

MODULAR CABLES

Thanks to their modularity, all unnecessary cables in the system are left out. Pure Power 12 M 1200W simplifies cable management and routing for a tidy-looking system. A smoother airflow results from the uncluttered layout of the system, which means lower noise and temperatures inside the case.
