Straight Power 12 is a future-proof ATX 3.0 power supply with 80 PLUS® Platinum certification and virtually inaudible 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.
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.
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.
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.
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.
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.
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.
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.
“With Straight Power we are aiming for sophisticated users and PC builders. We understand Straight Power as the PSU of choice for all who are not dependent on the sheer overwhelming feature set of a Dark Power, yet do not want to miss out on premium technology.”
Christian Joppien, Head of Global Product Management
