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 PSU can continuously supply to the computer's components. It is a good idea to use a web-based calculator to work out the optimal power output based on your chosen components.
Modern design inspired by the Montech brand
The Montech CENTURY II PC power supply impresses not only with its performance but also with its sophisticated design, which will perfectly complement your computer build. The elegant silver finish, new logo, and modern typography of the CENTURY II series create an attractive look that will stand out, especially in cases with a transparent side panel.
PC power supply with ATX 3.1 and PCIe 5.1 support
With the Montech CENTURY II 650W, you'll be ready for current and future PC builds. Thanks to support for the ATX 3.1 and PCIe 5.1 standards, the power supply can reliably handle short-term power spikes of up to 2× its rated power and up to 3× the rated power consumption of the graphics card. This gives you stable power even during sudden load increases, greater compatibility with modern hardware, and the assurance of reliable operation when gaming or working with demanding applications.
Montech CENTURY II ensures stable power even under heavy load
Thanks to its modern architecture featuring Active PFC, Half Bridge LLC, and DC-to-DC technologies, the Montech CENTURY II PC power supply delivers precise voltage regulation, high energy efficiency, and a stable power supply to all components. You can rely on stable operation even under heavy CPU and GPU load, whether you're playing the latest games, working with demanding applications, or creating content.
Reliable operation thanks to Japanese capacitors
The Montech CENTURY II PC power supply uses high-quality Japanese capacitors, which are known for their high reliability, stable performance, and long lifespan. In combination with the advanced power architecture, they ensure stable operation even under long-term load, so you can count on your computer running smoothly when gaming, working, or creating demanding content.
80 Plus Gold certification confirms lower energy consumption
The 80 PLUS Gold certification confirms high energy efficiency and more effective use of the supplied power. Thanks to lower energy losses, the PC power supply generates less heat, contributes to quieter operation, and provides stable power even under heavy load. Whether you're playing the latest games or working with demanding applications, the Montech CENTURY II 650W offers you reliable performance, economical operation, and long-term reliability.
Quiet and efficient cooling with an FDB fan
The PC power supply is equipped with a 135mm fan featuring a fluid dynamic bearing, which ensures efficient heat dissipation while maintaining low noise levels. Thanks to the high-quality bearing, you can rely on smooth operation, a long lifespan, and stable performance during both everyday use and heavy loads. The Montech CENTURY II thus contributes to the quiet operation of the entire computer build without compromising on cooling.
Minimal noise under low load
Thanks to the Smart Zero Fan function, the PC power supply's fan automatically stops at low loads, allowing you to enjoy virtually silent operation during normal work or while watching multimedia. At higher loads, the fan starts up smoothly to ensure the power supply is cooled effectively. The Montech CENTURY II 650W thus offers the ideal combination of low noise, reliable cooling, and long-term stable performance.
Fully modular PC power supply for modern graphics cards
The Montech CENTURY II 650W gives you maximum flexibility when building your PC, thanks to its fully modular design. You only need to connect the cables you actually need, which keeps the inside of the case tidy and ensures the cabling doesn't restrict airflow. Its modern set of connectors, including 12V-2x6, ensures compatibility with high-performance graphics cards that use this power delivery method, so you'll be ready to build a modern gaming or work PC.
Montech CENTURY II protects your PC with a comprehensive suite of protections
The Montech CENTURY II is equipped with a comprehensive suite of protections including OPP, OVP, UVP, SCP, OCP, and OTP, which protect the power supply and other components from overload, overvoltage, undervoltage, short circuits, overcurrent, and overheating. This means you can count on safe and stable operation for your entire computer system, even under heavy load.

80 Plus certification in the European market
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different 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.
| PC power supply load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82 % | 85 % | 82 % |
| 80 PLUS Bronze | 85 % | 88 % | 85 % |
| 80 PLUS Silver | 87 % | 90 % | 87 % |
| 80 PLUS Gold | 90 % | 92 % | 89 % |
