A Fully Modular Cabling System

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.

Incredible Efficiency

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.

• Supporting the latest ATX12V v2.31 and EPS12V v2.92 standards and backward compatible with ATX12V v2.2 and ATX12V v2.01 systems, the Corsair Professional Series GOLD AX650 provides maximum power stability to drive the processors as well as other components for desktop and server computer systems

• The 80 PLUS Gold certified power supply provides high power efficiency of at least 87% at any load between 20% and 100%, saving your money on your electrical bill, reducing heat in your computer's system and prolonging its life

• The Corsair Professional Series GOLD AX650 delivers 650W reliable, continuous output for mid-wattage computer systems. Powerful single +12V rail at up to 54A design ensures the maximum provision of 12V power to energy-hungry CPU and VGA card perfect for future high-end component upgrades or overclocking.

• The fully modular cable design allows only use of the cables you need to improve internal airflow and reduce clutter. Additionally, low-profile, flat cable design reduces air friction and helps maximize airflow through your computer's chassis.

• The Corsair Professional Series GOLD AX650 utilizes a low-noise, thermally-controlled 120mm fan, and employs sophisticated techniques to enhance cooling performance and reduce noise. This includes a specially designed PCB that channels airflow to reduce back-pressure and maximize the fan’s cooling ability.

• High-quality Japanese capacitors provide uncompromised performance and reliability. Over-voltage and over-current protection, under-voltage protection, and short circuit protection provide maximum safety to your critical system components
