Product information

Description

The Cooler Master GX II Gold 850 ATX 3.1 is a high-performance power supply unit engineered to provide reliable and efficient energy for modern PC and server builds. With an 850W power output and 80 PLUS Gold certification, this unit ensures stable operation even under demanding workloads. It features a fully modular design that simplifies cable management and promotes better airflow within your computer case, while the active cooling system with a 120mm fan maintains optimal temperatures during operation.

Advantages

This power supply unit stands out due to its full compliance with the ATX 3.1 standard, which includes a durable 12V-2x6 cable capable of delivering up to 600W to high-end graphics cards. The inclusion of a zero-RPM fan mode ensures silent operation during low-load tasks, as the fan only activates when the system reaches a specific temperature threshold. Furthermore, the use of high-quality Japanese capacitors reduces ripple noise and enhances overall component reliability, while the modular cabling system allows users to connect only the cables they need, significantly reducing clutter and improving internal system aesthetics.

Suitable for

  • High-performance gaming PCs
  • Professional workstations and servers
  • Systems requiring stable power for modern GPUs
  • PC builds where cable management and airflow are priorities

This unit may not be suitable for ultra-compact small form factor cases that do not support standard ATX power supplies. Additionally, for systems with extremely low power requirements, a lower-wattage unit might be more cost-effective.

Key specifications

  • Total power: 850 W
  • Efficiency: 80 PLUS Gold certified (over 90% at typical loads)
  • Form factor: ATX
  • Cooling: Active 120 mm fan with zero-RPM mode
  • Connectors: 24-pin ATX motherboard connector
  • Cabling: Fully modular
  • Input voltage: 100 - 240 V

How to use

To install the Cooler Master GX II Gold 850, first ensure your computer is powered off and disconnected from the wall outlet. Mount the power supply into your case using the appropriate screws, ensuring the fan intake is positioned to allow for adequate airflow. Connect the necessary modular cables to the power supply unit before installing them into your motherboard, GPU, and storage drives. Once all connections are secure, reconnect the power cable to the wall outlet and power on your system.

What to consider before purchase

  • Verify that your PC case supports the ATX form factor.
  • Ensure the 850W capacity meets the total power requirements of your hardware components.
  • Check the available space in your case for cable management.
Usage recommendations: For optimal performance and longevity, ensure the power supply fan intake is not obstructed by dust or case panels. Periodically check that all modular cable connections are firmly seated to prevent power instability.
