The Chieftec Polaris 1250W is a fully modular power supply unit designed for high-performance desktop PCs. It delivers a total power output of 1250 W, supports an AC input range of 100–240 V and is 80 PLUS Gold certified for improved energy efficiency. The unit includes a 20+4 pin ATX motherboard connector, a 140 mm active cooling fan and modular cables with a length of 650 mm to accommodate larger cases.

Advantages

The Polaris Series combines LLC half-bridge converter topology with DC-to-DC regulation to provide stable voltages and high power density in a relatively compact PSU. Full modular cabling simplifies system installation and cable management while the 80 PLUS Gold certification and efficient thermal design help reduce power losses and operating noise.

Suitable for

  • High-end gaming PCs with multiple GPUs or overclocked components
  • Workstations for content creation and 3D rendering
  • Large PC builds that require long modular cables
  • Systems demanding reliable continuous power delivery

Key specifications

  • Total power: 1250 W
  • 80 PLUS certification: 80 PLUS Gold
  • Motherboard connector: 20+4 pin ATX
  • AC input voltage: 100–240 V
  • Fan diameter: 140 mm (active cooling)
  • Cable length: 650 mm (modular cables)
  • Product colour: Black
  • Weight: 2.7 kg
  • Compliance: CE, RoHS

How to use

Install the Chieftec Polaris 1250W in a compatible ATX-compatible case following the motherboard and PSU manufacturer instructions. Connect the 20+4 pin ATX cable to the motherboard and attach the required modular cables to GPUs, drives and other peripherals. Ensure the AC input is within the specified 100–240 V range and secure proper airflow around the 140 mm fan for optimal cooling.

Recommendations

For stable operation, allow sufficient ventilation inside the case and use only the modular cables supplied with the unit. Verify total system power draw does not exceed 1250 W and follow local safety and grounding practices when connecting the PSU to mains power.
