Description

This Be Quiet brand power supply unit has an 80 PLUS Platinum energy efficiency certificate and a power output of 1200W.

This power supply is equipped with an exceptionally large 135 mm fan. Thanks to the larger blade size, it provides better airflow at lower speeds and quieter operation compared to standard 120 mm fans.

80 PLUS Platinum energy efficiency certificate, received by this power supply unit, guarantees at least 92% efficiency at 50% load. In other words, for every 100 W of energy that the power supply unit receives from the power grid, at least 92 W reaches your computer components, while the remaining 8 W is lost as heat.

The color of this power supply is Melna. The cable color is Melna and they are flat.

This power supply unit has been assigned the ATX 2.0 standard. This means that the unit is equipped only with 6-pin and 8-pin connectors, providing 75W and 150W power respectively. It's important to note that this unit will be compatible with RTX 4070 and more powerful cards, but you will need to use the 2x8-pin to 16-pin 12VHPWR adapter included with the graphics card. ATX 2.0 power connectors are not designed to handle the high power fluctuations of modern graphics cards; therefore, if you are building a system with a powerful GPU, such as the RTX 4070, we recommend choosing a power supply unit with the ATX 3.* standard and 12VHPWR (PCIe 5.0) connector.

This power supply unit has fully-modular cables (Fully-modular) – you can connect and disconnect all the included cables as needed, reducing clutter and improving ventilation. This will be useful for those with a partially transparent computer case and for whom the aesthetic factor is particularly important.

This power supply has been manufactured by Be Quiet. You can view all Be Quiet power supplies here.
