Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the form factor, is its power output. This indicates the maximum number of Watts the power supply can continuously deliver to the computer's components. It is a good idea to use a web calculator to determine the optimal power output based on your chosen components.
ATX 3.1 standard and PCle 5.1 readiness
The ATX 3.1 specification defines strict standards for voltage regulation and the ability to handle demanding peak loads. The design of this 650W PC power supply handles short-term power fluctuations reaching up to twice its rated output. This capability is crucial for the seamless operation of newer hardware, which places high demands on power delivery stability, and thus prevents system instability during sudden high loads.
PCIe 5.1 readiness
Thanks to the native 12V-2x6 connector, there's no need for bulky and unreliable adaptors for PCIe 5.1 standard graphics cards. This connector can deliver up to 450W through a single cable, and this solution simplifies the connection and increases the reliability of the power link. To maintain backwards compatibility, the power supply also includes two standard PCIe 6+2 pin connectors for older graphics cards, making it a versatile choice.
Optimised cooling
A specially designed 120mm Be quiet! fan takes care of efficient heat dissipation. Its blades have an aerodynamically optimised shape for quiet operation and high airflow even at low speeds. The Rifle bearing technology and 4-pole motor contribute to low operating noise, which reaches just 15.9 dB(A) at 100% load, while also supporting a long component lifespan exceeding 100000 operating hours.
Zero RPM mode for silent operation
Under low to medium loads, such as working in office applications or browsing the web, the fan does not spin at all. This semi-passive cooling mode eliminates any noise and contributes to a quiet environment. The fan activates automatically only after a certain power draw or temperature threshold is exceeded, meaning cooling is used only when it's truly necessary, while also reducing energy consumption.
Power stability and advanced topology
The 80 PLUS Gold certification confirms high electrical energy conversion efficiency, reaching up to 94.2% at 50% load. This directly leads to lower operating temperatures for the power supply, reducing the need for active cooling and thus the overall noise of the build. Higher efficiency means lower energy losses in the form of waste heat. Advanced topology with LLC, Synchronous Rectifier (SR), and DC-to-DC converter technologies contributes to exceptionally precise voltage regulation and high operational efficiency. The LLC technology ensures a stable voltage on the main 12V rail, while the DC-DC converters efficiently generate 3.3V and 5V from it. The result is a consistent power supply to all connected components, even during sudden and large load changes.
Fully modular cable management
All cables are detachable, giving the user full control over their management. You can connect only those that are truly needed for your build and leave the rest aside. This results in better airflow in the case, easier component installation, and an overall cleaner and more organised computer interior, which is especially noticeable in cases with a transparent side panel. In addition to one 12V-2x6 connector for graphics cards, it also includes two PCIe 6+2 pin connectors. Two CPU 4+4 pin connectors are used for powering the processor. There are also five SATA connectors for hard drives and SSDs, and two Molex connectors for peripherals or accessories.
Handling power peaks
The power supply's design reliably handles short-term power peaks, which can reach up to twice its rated output of 650W. This capability is essential for the seamless operation of powerful graphics cards and processors. The system thus remains stable even during the most demanding operations, such as high-resolution gaming or rendering, where rapid and high demands on power consumption occur.
Comprehensive protection systems with a strong 12V rail
An integrated set of safety features actively protects the connected hardware from damage due to electrical grid anomalies. It includes overvoltage, undervoltage, overcurrent, and overload protection. Additionally, there is protection against short circuits, overheating, and protection against inrush currents and surges. The power supply uses a single strong 12V rail, capable of delivering a current of up to 54.1A. This solution provides stable and consistent power for more demanding components like the processor and graphics card. A single powerful rail simplifies load distribution and is suitable for systems where these two components consume most of the power.

80 Plus certification on the European market
80 Plus certification was created to objectively evaluate the efficiency of PC power supplies. This provides users with a simple and clear comparison between models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
