Corsair CMPSU-850AX AX850 Power Supply

The Corsair CMPSU-850AX AX850 Power Supply pushes the state of the art for reliable delivery of clean power under imperfect conditions. If you require mission-critical stability or you simply want one of the best power supplies available, the Corsair CMPSU-850AX AX850 Power Supply is for you. All cables detach from the power supply. During installation, this gives you the flexibility of using only the cables you need for a clean system build with optimal airflow. And, when it's time to replace or upgrade your power supply, it can be removed from your system without interfering with your cabling — the cables stay in place and connect to your new fully-modular Corsair power supply.


With 90% efficiency at 50% load, the Corsair Professional Series Gold power supply runs quieter, generates minimal excess heat, and saves you money every month. The Corsair CMPSU-850AX AX850 Power Supply earned the 80 Plus Gold seal of approval, your guarantee that you're making the right choice for smart, efficient power delivery.

What It Is And Why You Need It:

  • A dedicated single +12V rail offers maximum compatibility with the latest components
  • High-quality Japanese capacitors provide uncompromised performance and reliability
  • Completely modular cable system allows you to use only the cables you need
  • Power supply upgrade and replacement is easy, as the cables only need to be disconnected at the power supply
  • Low-profile, flat cable design reduces air friction and helps maximize airflow through your computer's chassis
  • A seven year warranty and lifetime access to Corsair's legendary technical support and customer service
  • Over-voltage and over-current protection, under-voltage protection, and short circuit protection provide maximum safety to your critical system components
