Product information

Description

The Cooler Master MWE GOLD 850 V3 ATX 3.1 is a high-performance power supply unit engineered to provide reliable and efficient energy for modern desktop computers. With a total power output of 850W and 80 PLUS Gold certification, this unit ensures optimal power delivery while minimizing energy waste. It features a robust design that adheres to the latest ATX 3.1 standards, making it a future-proof choice for demanding PC builds that require stable voltage and consistent performance.

Advantages

This power supply unit stands out due to its high efficiency, which helps reduce electricity consumption and heat generation during operation. The integration of a 120mm active cooling fan ensures that internal components remain at safe operating temperatures even under heavy loads. Its durable construction and compliance with international safety standards provide peace of mind for users building high-end gaming rigs or professional workstations. The inclusion of a 24-pin ATX motherboard connector ensures broad compatibility with most modern motherboards, while the stable DC-to-DC circuit design maintains consistent power output.

Suitable for

  • High-performance gaming PCs
  • Professional workstations
  • Modern desktop computer builds requiring ATX 3.1 support
  • Systems requiring stable 850W power delivery

When it may not be suitable

This power supply unit is non-modular, which may not be ideal for users who prioritize advanced cable management in compact cases where excess cables can obstruct airflow. It is designed specifically for standard ATX desktop configurations and may not fit into specialized small form factor cases or proprietary server chassis.

Key specifications

  • Total power: 850 W
  • Efficiency: 80 PLUS Gold
  • Form factor: ATX 3.1
  • Cooling: 120 mm active fan
  • Motherboard connector: 24-pin ATX
  • Input voltage: 100 - 240 V
  • Weight: 1.8 kg
  • Colour: Black

How to use

To install the power supply, mount it into the designated PSU bay of your computer case using the provided screws. Connect the 24-pin ATX cable to the motherboard and attach the necessary power cables to your components, such as the CPU and graphics card. Ensure all connections are firmly seated before connecting the unit to a wall outlet. Once installed, the unit operates automatically, with the active cooling fan adjusting its speed based on the internal temperature of the power supply.

What to consider before purchase

  • Ensure your PC case supports the ATX form factor.
  • Verify that 850W is sufficient for your total system power consumption.
  • Consider that this is a non-modular unit, meaning all cables are permanently attached.
  • Check the clearance in your case to accommodate the cable lengths.

Usage recommendations

For optimal longevity and performance, ensure the air intake and exhaust areas of the power supply are free from dust and obstructions. It is recommended to use a surge-protected power strip to safeguard your components against electrical fluctuations.
