80 PLUS® PLATINUM CERTIFIED | Highly efficient operation

Straight Power 12 1500W is certified with 80 PLUS Platinum and an energy efficiency rating of up to 93.9%. 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 1500W is anATX 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 1500W of continuous power with one massive12V rail. Even if the graphics card demands excessive power for a short time: Straight Power 12 1500W 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

Thefunnel-shapedfan inlet of the Straight Power 12 1500W 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

Withfull bridge LLCStraight Power 12 1500W offers advanced technologies, resulting in higher efficiency, better regulation and lower ripple noise for an incomparably stable operation.
