Quiet! SystemPower 750W Power Supply

The be quiet! System Power 11 750W is a high-performance power supply unit (PSU) designed for users who seek reliable and quiet operation without compromising on performance. It is tailored for systems that require stable power delivery, especially for high-end graphics cards and other power-hungry components. The System Power 11 750W is built with advanced features that are typically found in higher-end PSUs, making it a strong contender in the entry-level segment. It supports the latest ATX 3.1 standard, ensuring compatibility with modern motherboards and components, including graphics cards with PCIe 5.1 or 6+2 pin connectors.

One of the standout features of this PSU is its silent, thermally regulated 120 mm fan, which ensures minimal noise during operation while maintaining efficient cooling. The unit also employs a robust single-rail 12V design, providing stable power delivery to all components connected to the system. This is particularly beneficial for high-performance systems that require consistent voltage regulation under heavy loads.

The System Power 11 750W utilizes DC-to-DC regulation technology, which enhances voltage stability and reduces electrical noise. This ensures that the power delivered to the system is clean and consistent, which is crucial for maintaining the longevity and performance of sensitive components like CPUs and GPUs. The PSU also includes a PCIe 5.1 12V-2x6 600 W connector and three PCIe 6+2 connectors, allowing for flexibility in powering high-end graphics cards.

In terms of efficiency, the System Power 11 750W is certified with an 80 PLUS Bronze rating, achieving a maximum efficiency of up to 90%. This means that it can convert a significant portion of the input power into usable output power, reducing energy waste and lowering electricity bills over time. The PSU also features a low standby power consumption of less than 0.15 W, making it energy-efficient even when the system is idle.

The System Power 11 750W is designed to operate within a wide range of input voltages (200-240 VAC), making it suitable for use in various regions with different electrical standards. It supports modern standby mode, allowing the system to enter a low-power state when not in use while still maintaining essential functions. The operating temperature range is up to 40°C, ensuring reliable performance in most environments.

The fan used in this PSU is specifically designed for silence optimization, featuring a rifle bearing and a four-pole motor for smooth and quiet operation. The maximum fan speed is rated at 2100 RPM, which provides adequate airflow without generating excessive noise.
