Product information

Description

The CORSAIR CP-9020256-EU is an 850 W ATX power supply unit designed to provide stable and efficient power for desktop computers. It supports a wide AC input range of 100–240 V and 47–63 Hz frequency, and features an 80 PLUS Gold efficiency rating to reduce energy loss and heat. The unit includes a standard 24-pin ATX motherboard connector, integrated active cooling with a 140 mm fan, and a suite of output cables including a 61 cm motherboard cable and multiple SATA leads of varying lengths suitable for common desktop builds.

Advantages

High efficiency at the 80 PLUS Gold level reduces wasted energy and improves thermal performance under load. The 140 mm fan provides active cooling with a balance of airflow and acoustic performance. A full 24-pin ATX connector ensures compatibility with standard motherboards, while the 850 W total power allows for multi-component systems including high-performance CPUs and multiple storage devices. The black finish integrates unobtrusively into most PC cases.

Suitable for (tasks / use cases)

  • Gaming desktops with mid to high power requirements
  • Workstation builds for content creation and multitasking
  • Systems with multiple HDD/SSD drives requiring several SATA power connectors
  • Upgrades where higher power and improved efficiency are needed

Key specifications

  • Total power output: 850 W
  • Motherboard connector: 24-pin ATX
  • Efficiency rating: 80 PLUS Gold
  • Cooling: 140 mm fan (active)
  • AC input range: 100–240 V, 47–63 Hz
  • Product colour: Black
  • Weight: 3.3 kg

How to use

Install the power supply into a compatible ATX case following the case and motherboard manufacturer instructions. Secure the unit with the provided screws, connect the 24-pin ATX cable to the motherboard, and attach required peripheral connectors such as SATA power leads to drives and any necessary PCIe or CPU power cables to components. Ensure AC mains voltage is set correctly if the unit includes a manual selector, or confirm automatic voltage support. After connections are verified, power on the system and monitor for stable boot and expected fan operation.

Usage recommendations

Use a compatible case with adequate ventilation and route cables to avoid obstructing airflow. For systems with high-power graphics cards or multiple storage devices, verify total system power draw and allow a safety margin below the 850 W rating. Regularly inspect connectors for secure seating and keep intake/exhaust areas free of dust to maintain cooling efficiency and prolong component life.
