The technology sector is developing rapidly – not only with graphics cards or processors, but also with seemingly inconspicuous but essential components such as power supply units. With the new System Power 11 series, be quiet! provides a convincing answer to modern requirements for performance, efficiency and future-proofing in the entry-level segment. Particularly exciting: The power supply units support the latest ATX 3.1 and PCIe 5.1 standards – rarely found in this price range to date.
Highlights
- New be quiet! power supply series with 450W to 750W output and ATX 3.1 compatibility
- PCIe 5.1 support for modern GPUs (from 550W model)
- Efficiency according to 80 PLUS® Bronze standard and quiet operation thanks to 120 mm fan
Powerful features for modern systems
The be quiet! System Power 11 series is aimed at users who want to build a reliable PC without having to invest in high-end components. With four models between 450W and 750W, the series covers a broad performance spectrum – ideal for office PCs, mid-range gaming systems or compact workstations.
Particularly noteworthy is the support for ATX 3.1 and PCIe 5.1 – standards that are actually only common in higher price ranges. The PCIe 5.1-compliant 12V 2×6 connection (from 550W model) enables the operation of modern graphics cards that rely on this new interface. Combined with a powerful single 12V rail and DC-to-DC technology, this ensures a stable power supply, even for demanding tasks such as gaming or rendering.
Efficient, safe – and above all: quiet
A trademark of be quiet! is its virtually silent operation – and this remains the case with the System Power 11 series. A temperature-controlled 120 mm fan cools the components efficiently without causing unnecessary noise. The choice of flat, black cables is not only visually attractive – it also facilitates cable management and promotes airflow in the case.
All models have 80 PLUS® Bronze certification, which stands for solid energy efficiency and reduces electricity costs at the same time. Extensive safety functions are integrated to protect the hardware, including protection against overload, overvoltage, undervoltage, short circuit and overheating. This positions the power supply unit as a safe and durable option, even for beginners – with a 5-year manufacturer’s warranty.
Conclusion: A lot of technology for little money
With the System Power 11 series, be quiet! delivers a strong overall package for all those who rely on the latest technology standards without having to dig deep into their pockets. Whether as an upgrade for older systems or as the basis for a new build – the power supply units offer solid performance, modern features and proven quality. The models will be available in stores from May 6. The recommended retail prices start at €49.90 for the 450W model and range up to €79.90 for the 750W variant. An attractive offer for all those who want to equip their PC quietly, efficiently and future-proof. You can find more information on the manufacturer’s official product page.
