Product information

Description

The Chieftec Polaris 550 W power supply unit delivers 550 W of continuous power in a compact ATX form factor. It is 80 PLUS Gold certified for high efficiency and uses a 120 mm active cooling fan. The PSU includes a 20+4 pin ATX motherboard connector and multiple SATA power connectors, and its fully modular cabling with 650 mm main cable length makes installation flexible for both compact and larger PC builds.

Advantages

The Polaris Series uses an LLC half-bridge converter with DC-to-DC technology to provide stable voltages and improved efficiency across loads. Its high power density allows a shorter 140 mm housing while keeping high output, and full modular cable management reduces clutter and simplifies system assembly and maintenance.

Suitable for

  • Home and office desktop PCs requiring up to 550 W
  • Compact ATX builds where a shorter 140 mm PSU is preferred
  • Systems needing reliable 80 PLUS Gold efficiency
  • Builds where modular cabling and longer cable reach are beneficial

Key specifications

  • Total power: 550 W
  • 80 PLUS certification: 80 PLUS Gold
  • Motherboard connector: 20+4 pin ATX
  • Fan diameter: 120 mm
  • Length: 140 mm (housing)
  • Product colour: Black
  • Weight: 2.025 kg

How to use

Install the PSU into a standard ATX case using the supplied screws and connect the 20+4 pin ATX connector to the motherboard. Attach required modular cables to the unit and then to drives and peripherals, observing connector types and orientations. Ensure the mains input is compatible (100–240 V, 50–60 Hz) and route cables to maintain airflow around the 120 mm fan.

Usage recommendations

For best results, pair the Chieftec Polaris 550 W with systems whose combined component power draw stays within the PSU’s rated capacity, and use the modular cabling to minimize airflow obstruction. Regularly check ventilation and dust levels around the fan to maintain cooling performance and efficiency.
