The be quiet! System Power 11 is an efficient and particularly quiet power supply for price-conscious PC enthusiasts. With ATX 3.1 support, modern protection, and stable power delivery, it is ideal for compact gaming and office systems.

– ATX 3.1 power supply with support for PCIe 5.1 graphics cards
– Two PCIe 6+2 connectors for efficient GPU power
– Operates with up to 89% efficiency (80 PLUS Bronze)
– Temperature-controlled 120mm fan for quiet operation
– Safety features: OCP, OVP, UVP, SCP, OTP, OPP
– Ready for modern hardware and GPUs

The System Power 11 is a 140mm deep ATX form factor power supply – perfect for powerful desktop PCs and fits into most common cases. With ATX 3.1, you get maximum efficiency and are perfectly prepared for future hardware – optimized power consumption, faster transient response, and full compatibility with PCIe 5.1. It supports mid-range graphics cards with two PCIe 6+2 connectors and offers high stability in cross-load scenarios.

The power supply is equipped with a single-rail power supply and is ideal for powerful hardware, as it concentrates all available power on a single 12V rail and reliably supplies high loads.

The 450-watt power supply provides stable and reliable power for office, multimedia systems, and small gaming PCs.

Quiet operation in a compact format
Thanks to semi-passive cooling, the fan remains off when idle and only spins up when power increases, ensuring whisper-quiet operation. The temperature-controlled 120mm fan ensures quiet airflow and efficient cooling – ideal for home offices, media, and gaming PCs.

With its optimized cooling and semi-passive operation, this power supply is ideal for silent and gaming PCs, as it minimizes annoying fan noise and also offers reliable performance.

High-level efficiency and protection
80 PLUS Bronze – Solid efficiency with up to 89% efficiency under typical load at 230V. At the same time, extensive protective circuits reliably protect against voltage spikes, short circuits, and overloads.
