be quiet! System Power 11 BP011

Moderately powerful and fairly quiet ATX standard power supply unit from the German manufacturer Be Quiet. Represents the System Power line from the German brand be quiet, which includes classic power supply units with good efficiency, decent technical characteristics, and a quiet cooling system at an adequate cost. Compared to previous models in the System Power series, it now supports the ATX 3.1 format.

According to the manufacturer, it will become a reliable foundation for gaming PCs and moderately powered workstations with a mid-class processor and GPUs like the GeForce RTX 4070 or Radeon RX 9600 XT. With a declared efficiency of 89% and 80 PLUS Bronze certification, the be quiet! System Power 11 delivers honest 650 watts of power, with the entire load on the 12-volt line, which is especially important for modern systems with energy-intensive CPUs and GPUs.

Active PFC, a full set of overvoltage, overload, and overheating protections, as well as protection against undervoltage and surge protection emphasize the reliability of the device. The cooling system is based on a 120-mm fan with a sliding bearing, which remains practically inaudible in everyday scenarios and does not exceed 31 dB even at maximum load. The extended set of protective functions includes OCP (overcurrent protection), OVP (overvoltage protection), OPP (overpower protection), OTP (thermal protection), UVP (undervoltage protection), and SIP (surge protection). Rounding out the picture is a 5-year manufacturer warranty.
