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.
