Product information

Description

The Chieftec Polaris 750 W is a fully modular ATX power supply designed for desktop PCs. It delivers 750 W of total power with an 80 PLUS Gold efficiency rating and compact dimensions (140 mm length). The unit includes a 20+4 pin ATX motherboard connector, multiple SATA power leads, and an active cooling solution with a 120 mm fan, meeting RoHS compliance for safer materials.

Advantages

The Polaris 750 W combines a high-efficiency 80 PLUS Gold certification with a modern LLC half-bridge converter and DC-to-DC topology to provide stable voltages and improved power density. Fully modular cabling simplifies installation and cable management, while the 140 mm compact length and long cable runs (up to 650 mm) make the PSU suitable for both compact and larger PC builds.

Suitable for

  • Gaming desktops with mid to high power requirements
  • Workstations requiring stable 12 V rails and modular cabling
  • Compact ATX builds where a shorter PSU is needed
  • Systems needing multiple SATA devices

Key specifications

  • Total power: 750 W
  • Certification: 80 PLUS Gold
  • Motherboard connector: 20+4 pin ATX
  • AC input: 100–240 V, 50–60 Hz
  • Fan diameter: 120 mm (active cooling)
  • Length: 140 mm
  • Cable lengths: motherboard cable 650 mm; SATA cables 150 mm and 450 mm
  • Colour: Black
  • Weight: 2.285 kg

How to use

Install the Chieftec Polaris 750 W into a standard ATX PSU bay using the provided mounting screws. Connect the 20+4 pin ATX cable to the motherboard, attach the modular PCIe and SATA cables as required for drives and peripherals, and connect the AC power cord to a compatible mains outlet (100–240 V, 50–60 Hz). Ensure all connectors are fully seated before powering on the system.

Usage recommendations

For optimal lifespan and stable operation, use the Polaris 750 W with systems whose total continuous power draw remains within the PSU’s capacity, maintain adequate case airflow for the 120 mm fan, and connect only the necessary modular cables to reduce clutter and improve cooling.
