80 PLUS Platinum Certification

Highly efficient operation
Straight Power 12 1200W is certified with 80 PLUS Platinum and an energy efficiency rating of up to 93.7%. This provides lots of benefits for your high-end system, including less power consumption and an overall cooler and quieter operation.

Future-Proof System
Fulfills all ATX 3.0 specifications
Straight Power 12 1200W is an ATX 3.0 PSU and comes with both native integration of 2 12VHPWR connectors for next-generation PCIe 5.0 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
For massive transient loads
Straight Power 12 offers 1200W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time_ Straight Power 12 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.

Silent Wings Fan
Provides virtually inaudible operation
The high-end Silent Wings fan delivers best-of-class airflow yet produces very little noise. This is thanks to its unique, optimized fan blade design along with an advanced fluid-dynamic bearing and 6-pole fan motor that largely eliminates operational noise, has a super-long life and minimal
power consumption.

Flawless Cooling Concept
For a longer lifespan
The funnel-shaped fan inlet of the Straight Power 12 1200W increases airflow while reducing unwanted turbulence for a higher cooling performance. The wire-free design inside allows the cool air to reach all components which ultimately leads to a longer lifespan.

State-Of-The-Art Technologies

Rock-steady signal stability and efficiency
With full bridge LLC Straight Power 12 1200W offers advanced technologies, resulting in higher efficiency, better regulation and lower ripple noise for an incomparably stable operation.

Japanese 105C Capacitors

A testament to high quality
Only premium components are used in Straight Power 12 1200W. That is why this PSU features exclusively high-quality Japanese capacitors. They are rated at 105C for stability, reliability, and a long operating life.

Convinience and Connectivity

Maximum utility
Modular, sleeved cables of up to 100cm in length simplify component installation and reduce annoying clutter. This results in increased airflow and improved cooling - even in the largest PC cases.
