80 PLUS® Platinum Certified

Highly efficient operation

Straight Power 12 850W is certified with 80 PLUS Platinum and an energy efficiency rating of up to 94%. This provides lots of benefits for your high-end system, including less power consumption and an overall cooler and quieter operation.

 

 

 

Future-Proof Your System

Fulfills all ATX 3.0 specifications

Straight Power 12 850W 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 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 850W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time: Straight Power 12 850W 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 850W 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 850W offers advanced technologies, resulting in higher efficiency, better regulation and lower ripple noise for an incomparably stable operation. 

 

 

Japanese 105° Capacitors

A testament to high quality

Only premium components are used in Straight Power 12 850W. That is why this PSU features exclusively high-quality Japanese capacitors. They are rated at 105°C for stability, reliability, and a long operating life.
