Product information

Description

The Cooler Master MWE GOLD 850 V3 is a high-performance 850W power supply unit designed to meet the demands of modern desktop computing. Built to the ATX 3.1 standard, this unit provides stable and efficient power delivery for high-end components. It features 80 PLUS Gold certification, ensuring high energy efficiency during operation, and utilizes active cooling with a 120mm fan to maintain optimal thermal conditions. The non-modular design is built for durability and consistent performance in a wide range of PC builds.

Advantages

This power supply unit stands out due to its robust construction and advanced electrical design. The inclusion of DC-to-DC technology combined with an LLC circuit ensures stable voltage regulation, which is critical for protecting sensitive computer hardware. The 80 PLUS Gold efficiency rating helps reduce energy waste and heat generation, contributing to a more sustainable system. Furthermore, the active cooling system with a 120mm fan operates quietly, ensuring that the unit remains cool even under load without creating excessive noise. Its compliance with the ATX 3.1 standard makes it future-proof for the latest hardware requirements.

Suitable for

  • High-performance gaming desktop PCs
  • Workstations requiring stable power delivery
  • Systems utilizing modern graphics cards and processors
  • General-purpose desktop upgrades

When it may not be suitable

This unit is non-modular, meaning all cables are permanently attached to the power supply. If you are building in a very small form factor case where cable management space is extremely limited, a modular power supply might be a better choice to reduce cable clutter. Additionally, if your system requires significantly less than 850W, you may find more cost-effective options with lower wattage ratings.

Key specifications

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

How to use

To install the Cooler Master MWE GOLD 850 V3, ensure your computer is powered off and disconnected from the wall outlet. Mount the power supply into your PC case using the appropriate screws, ensuring the fan intake is unobstructed. Connect the 24-pin ATX cable to the motherboard and attach the necessary power cables to your CPU, graphics card, and storage drives. Once all connections are secure, reconnect the power cable to the wall outlet and switch the unit on.

What to consider before purchase

  • Ensure your PC case supports the ATX form factor.
  • Verify that your components do not exceed the 850W power limit.
  • Consider the non-modular cable design regarding your case's cable management capabilities.
  • Check the length of the included cables to ensure they reach your components comfortably.

Usage recommendations

For optimal longevity and performance, ensure the power supply fan has adequate clearance for airflow and keep the air intake area free of dust. It is recommended to use a surge-protected power strip to provide an extra layer of electrical safety for your system.
