Product information

Description

The Montech CENTURY II 850W is a high-performance ATX power supply unit designed to provide stable and efficient power for modern desktop computers. Featuring 80 PLUS Gold certification, this unit ensures optimal energy conversion, reducing waste and heat generation. It is built with high-quality components, including Japanese capacitors and an advanced circuit design, to ensure long-term reliability and consistent power delivery for demanding hardware configurations.

Advantages

This power supply unit stands out due to its modular design, which allows for cleaner cable management and improved airflow within the PC case. The inclusion of a 135mm Fluid Dynamic Bearing fan provides efficient cooling while maintaining low noise levels, even under heavy loads. With support for the latest ATX 3.1 and PCIe 5.1 standards, including a dedicated 12V-2x6 cable, it is fully compatible with modern high-end graphics cards. Furthermore, the unit incorporates comprehensive safety protections such as over-power, over-voltage, and short-circuit protection to safeguard your system components.

Suitable for

  • High-performance gaming PC builds
  • Workstations requiring stable power delivery
  • Systems utilizing modern high-power graphics cards
  • PC builds where cable management and aesthetics are a priority

This power supply may not be suitable for ultra-compact small form factor (SFF) cases that require SFX power supplies rather than standard ATX units. Additionally, for systems with extremely low power consumption, an 850W unit may be overkill, and a lower-wattage model might be more cost-effective.

Key specifications

  • Total power: 850 W
  • Efficiency certification: 80 PLUS Gold
  • Form factor: ATX
  • Cooling: 135 mm active fan
  • Motherboard connector: 20+4 pin ATX
  • Modular design: Fully modular
  • Safety protections: OPP, OVP, UVP, SCP, OCP, OTP

To use the Montech CENTURY II, install the unit into your PC case using the provided mounting screws. Connect the 20+4 pin ATX cable to your motherboard and the necessary CPU and PCIe cables to your components. Because the unit is fully modular, you only need to attach the cables required for your specific build, which helps keep the interior of your computer organized. Ensure all connections are firmly seated before powering on the system.

What to consider before purchase

  • Verify that your PC case supports the ATX form factor
  • Ensure your total system power draw aligns with the 850W capacity
  • Check that your graphics card requires the included 12V-2x6 or standard PCIe connectors
  • Confirm the physical dimensions fit your specific chassis layout
For optimal performance and longevity, ensure the power supply intake fan has sufficient clearance from the bottom or side of the case to allow for proper airflow. Regularly clean dust from the fan intake to maintain quiet operation and thermal efficiency.
