The be quiet! System Power 11 550W is a high-performance power supply unit designed for users who seek reliability and quiet operation without compromising on performance. It is tailored for those who want an affordable yet dependable power solution for their PC builds. This power supply stands out in its class with advanced features such as compatibility with the ATX 3.1 standard and a thermally regulated silent fan. It is ideal for systems that require stable power delivery and efficient cooling, especially when paired with high-end graphics cards that use PCIe 5.1 or 6+2 pin connectors.
The System Power 11 550W provides a continuous power output of 550 watts, ensuring sufficient energy for even demanding components. It features a single 12V rail, which enhances stability and ensures consistent power delivery to all components. The power supply uses DC-to-DC regulation technology, which improves voltage stability and reduces electrical noise. This makes it suitable for high-performance systems where reliability is crucial.
The power supply includes a 120 mm thermally regulated fan that adjusts its speed based on the internal temperature, ensuring quiet operation under normal loads while maintaining adequate cooling when needed. The fan is designed to be exceptionally silent, with noise levels as low as 10.4 dB(A) at 20% load. This makes it an excellent choice for users who prioritize a quiet computing environment.
The System Power 11 550W also includes a PCIe 5.1 12V-2x6 connector rated for 300 W, along with two additional PCIe 6+2 pin connectors, providing flexibility for high-end graphics cards. It is certified by 80 PLUS Bronze, indicating an efficiency of up to 89.7% at full load, which helps reduce energy consumption and heat output.
The power supply supports modern standby mode, allowing the system to consume less than 0.15 W in standby, which is beneficial for energy conservation. It operates within a wide input voltage range of 200-240 VAC and is designed to function in temperatures up to 40°C, making it suitable for various environments.
With a double forward + DC-DC topology and digital control, the System Power 11 550W ensures efficient and stable power delivery across different loads. Its design also includes a rifle bearing fan motor with a four-pole motor, contributing to its durability and quiet operation.
