be quiet! System Power 9 CM BN303 (BN303)

A unique power supply from the German company Be quiet. The model was created in the ATX form factor and received a power of 700 W, which opens up the possibility of servicing even a powerful and performant computer system in front of the device. The circuitry is built on DC-DC converters, which guarantees extremely stable electric current parameters. Energy efficiency certified to 80 PLUS BRONZE.

Among other things, this model boasts half-modular wiring. The main wires (power cables for the motherboard and CPU) of the Be quiet System Power 9 CM BN303 are non-removable, while the rest of the wiring can be used as needed. The semi-modular concept has a positive effect on the ventilation of the system unit, since unused wires will not clutter up the interior space. At the same time, the wiring is long enough to use the regular cable management channels of the "system unit". The power supply received an extremely quiet fan, while the cooler is equipped with a system for automatically selecting the rotation speed of the bladed impeller, due to which the fan speed increases in proportion to the load on the power supply. The list of interfaces includes 4 PCI-E connectors with a 6 + 2 pinout scheme, as well as 10 SATA.
