be quiet! System Power 11 650 W Power Supply
ATX power supply with 650 W output and 80 PLUS Bronze certification
The System Power 11 650W is designed for value-oriented users who do not want to compromise on reliability and quiet operation. Modern features such as ATX 3.1 compatibility and a temperature-controlled fan highlight the value that the System Power 11 650W offers in the entry-level segment.
Features
The power supply complies with the ATX 3.1 standard and offers full support for PCIe 5.1 graphics cards as well as GPUs with PCIe 6+2 connectors. A temperature-controlled, noise-optimized 120 mm fan from be quiet! ensures quiet operation. Stable operation is ensured by a powerful 12V rail as well as precise voltage regulation using a DC/DC converter. For high-performance graphics cards, a PCIe 5.1 12V 2x6 connector with up to 450 watts as well as two additional PCIe 6+2 connectors are available. Standby power consumption is less than 0.15 watts, and efficiency reaches up to 89.7% according to the 80 PLUS Bronze certification.
Meets all ATX 3.1 specifications
The System Power 11 650W is an ATX 3.1 PSU and comes with a 12V 2x6 connector for next-gen PCIe 5.1 graphics cards and 2 PCIe 6+2 connectors for current graphics cards. This makes the System Power 11 650W extremely versatile and the perfect choice for all current and future-proof high-end systems
Very quiet operation
The System Power 11 650W is equipped with a temperature-controlled 120 mm quality fan. It offers the quiet operation known for be quiet! and remarkable for the entry-level price.
Proven reliability for CPU and GPU
The System Power 11 650W offers a stable power supply with strong voltage regulation for the CPU and GPU. This ensures reliable operation even under heavy cross loads.
Powerful 12V rail for stable operation of a PCIe graphics card
The System Power 11 650W offers enough power even for demanding graphics cards. Safety features for comprehensive protection against overcurrent, overvoltage and undervoltage as well as short circuits, overheating and overload.
80 PLUS Bronze
The 80 PLUS Bronze certification of this power supply ensures that an efficiency of at least 81% is achieved at 100% load. This means that less of the energy used is converted into heat, resulting in less heat, lower energy consumption and thus less ventilation requirement.
