be quiet! SYSTEM POWER 11 750W - Power Supply

be quiet! SYSTEM POWER 11 750W arrives as a reliable ATX PSU designed for demanding PC builds and maintains high standards in performance and protection.

This 750 W power supply supports AC input from 200–240 V at 50 Hz and delivers a combined +12V output of 750 W through a single powerful rail, making it well suited for gaming rigs and workstation systems that need stable main rail delivery.

With an efficiency of 90% and an 80 PLUS Bronze certification, the SYSTEM POWER 11 balances energy savings with affordability. It features a power factor of 0.98 and a hold-up time of 17.34 ms to keep your system stable during brief interruptions.

Protection is comprehensive and includes over current, over power, over voltage, overheating, short circuit, surge & inrush, and under voltage safeguards, helping to protect expensive components. Compliance certificates such as CB, CE, RoHS, TÜV mark, UKCA and WEEE underline its regulatory readiness.

The non-modular cabling harness includes a 20+4 pin ATX main connector, an 8-pin EPS connector (EPS 2.92 compatible), three 6+2 pin PCIe connectors plus one 12-pin PCIe, six SATA power connectors, one Molex peripheral connector and a CPU 4-pin, covering a wide variety of motherboard and peripheral layouts.

Cooling is provided by a single 120 mm rifle-bearing fan running up to 2100 RPM and producing around 33.4 dB of noise under load, while the active cooling and compact ATX form factor (150 x 86 x 140 mm) keep installation straightforward. The unit weighs 2.04 kg and comes boxed with screws and cable ties included.

Typical use cases include mid-to-high-end gaming PCs, content-creation workstations, and office systems requiring reliable continuous power and thorough safety features. Its combination of a strong +12V rail, multiple PCIe connectors and 80 PLUS Bronze efficiency make it especially attractive for GPU-heavy builds.

Key selling points: 750 W single +12V rail, 80 PLUS Bronze efficiency, extensive protection suite, broad connector selection (including 12‑pin PCIe), and industry compliance for safe, long-term operation.
