be quiet! SYSTEM POWER 11 750W ATX 3.1 Power Supply

For office workstations and desktop systems that run demanding workloads every day, a stable power supply directly determines uptime. The be quiet! SYSTEM POWER 11 is a 750W ATX PC power supply with 80 PLUS Bronze efficiency, delivering consistent voltages under sustained load. It is aimed at businesses and system integrators building or upgrading desktop PCs with a focus on reliability and predictable operating costs.

With 750W of capacity, the unit handles configurations built around multi-core processors and dedicated graphics cards, with headroom for future upgrades. 80 PLUS Bronze efficiency limits the energy lost as heat, which translates into lower electricity costs over the system's service life. Active PFC keeps power draw from the grid balanced, while the 120 mm fan holds noise at 33.4 dBA, suitable for open-plan offices. Built-in protection against overcurrent, overvoltage, undervoltage, short circuits, overheating, overload and power surges safeguards system components when the mains supply fluctuates.

Compliance with ATX 12V 3.1 and EPS 12V 2.92 ensures compatibility with current motherboards and platforms. Connectivity includes a 24-pin (20+4) main connector, two 8-pin CPU connectors (one 4+4 and one EPS 12V), three 8-pin (6+2) PCIe connectors for graphics cards and six SATA connectors for SSDs and HDDs. At 150 × 140 × 86 mm, the unit fits standard ATX cases, and its 200–240V input range matches 230V mains networks.

The SYSTEM POWER 11 750W fits workstations for CAD design, photo and video editing and software development, where the CPU and GPU stay under load for hours. For IT departments refreshing their PC fleet, it provides a uniform, predictable power foundation across several generations of components. System integrators can adopt it as a standard for mid-range office builds, while its quiet operation keeps open-plan workspaces comfortable without trading off power stability.
