be quiet Straight Power 12 1200W power supply ATX 30 80 PLUS Platinum virtually inaudible Silent Wings fan for PCIe 50 and P

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

Silent operation

be quiet! Straight Power 12 1200W is a German power supply with a premium Full-Bridge topology and an almost indistinguishable fan. A proprietary 135mm be quiet! Silent Wings with a funnel-shaped frame, aerodynamic grooves on the blades, 6-pole motor and hydro-dynamic bearing.

Meter wires

It is capable of operating in a wide range of 110 - 240 volts, so it can cope even with severe voltage drops in a household power outlet. All cables are modular, you can choose between 16-pin and 8-pin video card cables, and the processor cable is a full meter long. This allows it to be hidden behind the back wall even in a very large computer case.

A whole decade

The Platinum Energy Efficiency Certificate not only helps you save on your energy bills, but also minimizes waste heat generation at just 6%. And in standby mode, the power supply consumes a negligible 0.1 W of electricity. The use of the most durable Japanese capacitors allowed the manufacturer to provide a ten-year warranty on the power supply.
