Product information

Description

The Montech BETA 2 850W ATX power supply unit is a reliable and efficient solution designed to provide stable power for modern desktop PC systems. With its 80 PLUS Bronze certification, this unit ensures effective energy conversion, reducing waste and heat during operation. The non-modular design features a standard 20+4 pin ATX motherboard connector, making it compatible with a wide range of computer cases and motherboards. Built to handle a broad AC input range of 100-240V, it is suitable for use in various electrical environments globally.

Advantages

The Montech BETA 2 offers a robust power architecture that utilizes DC-to-DC technology to maintain tight voltage regulation, ensuring that your system components receive consistent power even under varying loads. The inclusion of a high-quality 120mm active cooling fan provides efficient thermal management, keeping the unit cool while maintaining low noise levels during operation. Its durable construction and adherence to international safety standards, such as RoHS and TÜV, provide peace of mind regarding both safety and long-term reliability for your desktop build.

Suitable for

  • Standard desktop PC builds
  • Office and home workstations
  • Gaming systems requiring stable 850W power delivery
  • Upgrading existing ATX-based computer systems

This power supply may not be suitable for users who require a fully modular cable management system, as the non-modular design means all cables are permanently attached to the unit. It is also not intended for ultra-compact small form factor (SFF) builds where space for excess cabling is extremely limited.

Key specifications

  • Total power: 850 W
  • Form factor: ATX
  • Efficiency certification: 80 PLUS Bronze
  • Cooling: 120 mm active fan
  • Input voltage: 100-240 V
  • Motherboard connector: 20+4 pin ATX
  • Color: Black

To use the Montech BETA 2, ensure your PC case supports the standard ATX form factor. Install the unit into the designated power supply bay of your chassis, securing it with the appropriate screws. Connect the 20+4 pin ATX cable to your motherboard, and attach the necessary peripheral and CPU power cables to your components. Ensure all connections are firmly seated before switching on the power supply via the rear toggle switch.

What to consider before purchase

  • Verify that your PC case has sufficient space for a standard ATX power supply.
  • Confirm that the non-modular cable design meets your requirements for cable management.
  • Check the power requirements of your graphics card and processor to ensure 850W is sufficient for your specific hardware configuration.
Usage recommendations: For optimal performance and longevity, ensure the power supply intake fan is not obstructed by dust or case panels. It is recommended to use a surge-protected power strip to safeguard your system against unexpected voltage spikes.
