Product information

Description

The Chieftec Polaris 1250W 20+4 pin ATX Black is a high-capacity computer power supply designed for demanding desktop systems. It delivers up to 1250 W of continuous power, supports an AC input range of 100–240 V and carries an 80 PLUS Gold efficiency rating. The unit uses a 20+4 pin ATX motherboard connector and fully modular cabling to simplify system builds and cable routing while an active cooling solution with a 140 mm fan maintains stable operating temperatures.

Advantages

This power supply combines high efficiency and fully modular cable management, reducing heat and improving airflow inside the case. The 80 PLUS Gold certification and modern power-conversion topology (LLC half-bridge with DC-to-DC) provide consistent voltage regulation and lower energy losses under load. The included long cables and compact high power-density design make the unit suitable for large builds while keeping installation and maintenance straightforward.

Suitable for

  • High-performance gaming PCs with multiple GPUs
  • Workstations for video editing, 3D rendering and CAD
  • Overclocked systems requiring stable power delivery
  • Custom builds where modular cabling and cable management are priorities

Key specifications

  • Total power: 1250 W
  • Input voltage: 100–240 V, 50–60 Hz
  • Efficiency certification: 80 PLUS Gold
  • Motherboard connector: 20+4 pin ATX
  • Cooling: active fan, 140 mm diameter
  • Modularity: fully modular cable system
  • Weight: 2.7 kg
  • Colour: Black

How to use

Before installation, disconnect power from the mains and follow ESD precautions. Mount the power supply in the case using the provided screws with the fan oriented according to your case airflow design. Connect the 20+4 pin ATX to the motherboard and attach additional modular cables for GPUs, storage and peripherals as required. Confirm secure connections and cable routing to avoid obstructing airflow. Reconnect mains power and power on the system to verify stable operation and correct fan function.

Usage recommendations

Use this PSU in systems whose total continuous power draw stays within recommended margins of the unit’s 1250 W rating; leave headroom for peak loads. Maintain adequate case ventilation and periodically check the fan and modular connectors for dust accumulation. For optimal efficiency, operate the PSU within typical mains voltages and avoid prolonged operation near maximum rated load.
