be quiet! System Power 11 450W 80plus Bronze

The be quiet! System Power 11 450W is a power supply designed for reliability, energy efficiency, and quiet operation, even in intensively used systems. With its 80 PLUS Bronze certification, it guarantees optimal energy use, reducing power consumption and heat generation compared to less efficient models.

Equipped with a 120mm be quiet! fan optimized for silence, this power supply maintains stable temperatures with minimal noise, ideal for those looking for a powerful yet quiet PC. Its Rifle bearing technology and 4-pole motor extend the fan's life and ensure constant airflow at all times.

The 12V single rail design offers rock-solid stability to power modern CPUs and GPUs, enabling stable performance even under high loads. Thanks to its dual-forward topology with DC-to-DC conversion, the System Power 11 ensures precisely regulated voltages, protecting system components from power fluctuations.

It also incorporates a complete set of electronic protections (OCP, OVP, UVP, SCP, OPP, OTP, SIP) that protect components from overcurrent, overheating, or voltage spikes. Its robust design, combined with a lifespan of over 100,000 hours, makes the System Power 11 a reliable solution for desktop and workstation PCs.
