Very high performance

Pure Power 12 M 1200 W is 80 PLUS Gold certified with up to 93.7% efficiency. A convincing advantage: lower power consumption and thus lower costs, as well as cooler and quieter operation. Pure Power 12 M 1200 W is a good choice for quiet configurations and gaming PCs!

Meets all the requirements of the ATX 3.0 specification

Pure Power 12 M 1200 W is an ATX 3.0 power supply with native integration of 12VHPWR connector for PCIe 5.0 graphics cards and PCIe 6+2-pin connectors to support current generation GPUs. This makes the power supply extremely versatile and an excellent choice for current and future high-end configurations.

For massive transient loads

Pure Power 12 M offers 1,200 watts of continuous power with 2 independent 12-volt lines. Even if your graphics card requires excessive power for short periods of time: Pure Power 12 M 1200 W can easily handle power spikes of up to twice its rated power. This ensures reliable operation with the next generation of processors and graphics cards.

Extremely quiet operation

The ultra-quiet fan is temperature-controlled to achieve a better balance between efficient cooling and silence. Airflow-optimized fan blades reduce turbulence for quiet operation.

Incredible stability

Thanks to its LLC topology, Pure Power 12 M 1200 W provides better performance and voltage regulation. That's why it's ideal for building ultra-quiet configurations or upgrading gaming and multimedia PCs.

Maximum convenience and compatibility

Thanks to modularity, you can remove all unnecessary cables from your setup. Pure Power 12 M 1200 W simplifies cable management, cable routing, providing an orderly system. Smoother airflow results from an orderly layout, which means lower noise levels and temperatures inside the case.
