Product information

Description

The CHIEFTEC Polaris 3.0 1250W power supply unit complies with Intel ATX 3.0 and supports PCIe Gen5 while carrying an 80 PLUS Gold efficiency certification. It is built with an LLC half-bridge converter and DC-to-DC topology, uses Japanese main capacitors for low ripple and stable voltages, and includes a fully modular cable system. The unit features a 135 mm FDB fan that balances cooling and noise and is intended for desktop PC builds.

Advantages

The power supply delivers up to 1250 W of continuous power with an AC input range of 100–240 V and 50/60 Hz compatibility. Certified 80 PLUS Gold efficiency reduces wasted energy and heat. High-quality internal components, including Japanese capacitors and DC-to-DC circuitry, provide tight voltage regulation and low ripple. Fully modular cables simplify installation and improve case airflow. The 135 mm fluid-dynamic bearing (FDB) fan is designed for long life and quiet operation.

Suitable for

  • High-performance gaming PCs with multi-GPU or powerful single GPUs
  • Workstations for content creation, rendering and simulation
  • Custom desktop builds requiring modular cabling and stable power delivery

How to use

Install the PSU in a compatible ATX chassis following the motherboard and case manufacturer instructions. Connect the 20+4 pin ATX cable to the motherboard and use modular cables for CPU, GPU and storage devices as required. Ensure the AC mains voltage matches the unit’s input range (100–240 V) and secure all connectors. Allow space for airflow around the 135 mm fan and route cables to maintain good case ventilation.

Usage recommendations

For reliable operation, keep the power supply and system environment free of dust, use a properly rated surge protector or UPS if mains quality is unstable, and ensure the case provides adequate airflow to maintain cooling efficiency.
