Product information

Description

The Chieftec Polaris PPS-850FC is an 850 W ATX power supply designed for desktop PC builds that require high efficiency and reliable power delivery. It is 80 PLUS Gold certified and uses modern converter topology with DC-to-DC circuits to provide stable voltages in a compact chassis. The unit includes a 14 cm cooling fan and fully modular cabling, with a 20+4 pin motherboard connector and varied cable lengths to suit different case layouts.

Advantages

The Polaris PPS-850FC offers high energy efficiency thanks to its 80 PLUS Gold certification and a design that combines an LLC half-bridge converter with DC-to-DC technology. Its fully modular cables and 650 mm motherboard cable length simplify cable management for medium and large builds. The compact dimensions and high power density allow for strong power output within a relatively small enclosure, while a 140 mm fan provides active cooling with reduced noise at typical load levels.

Suitable for

  • Gaming PCs with mid to high power demands
  • Workstations requiring stable 12 V and auxiliary rails
  • Custom builds that benefit from modular cabling and neat cable routing
  • Systems where energy efficiency is important

Key specifications

  • Total power: 850 W
  • Motherboard connector: 20+4 pin ATX
  • 80 PLUS certification: 80 PLUS Gold
  • Cooling fan diameter: 140 mm
  • AC input: 100–240 V, 50–60 Hz
  • Dimensions: 150 x 160 x 86 mm (W x D x H)
  • Weight: 2.6 kg
  • Product colour: Black

How to use

Install the PSU into a compatible ATX case following the case manufacturer's instructions and standard safety precautions. Connect the 20+4 pin motherboard connector to the board's main power socket and attach modular cables for CPU, GPU, storage and peripherals as needed. Ensure the AC mains cable is connected to a properly rated outlet and switch the PSU on via the case or rear power switch. Verify BIOS/UEFI and system stability after first power-up.

Usage recommendations

For optimal performance and cable management, route the fully modular cables behind the motherboard tray when possible and use only the required connectors. Maintain adequate airflow around the 140 mm fan, and keep the PSU dust-free to preserve efficiency and cooling. Ensure the total system power draw remains within the 850 W rating, allowing headroom for peak loads.
