Product information

Description

The CHIEFTEC Polaris 3.0 850W power supply unit complies with Intel ATX 3.0 and supports PCIe Gen5 devices while offering 80 PLUS Gold efficiency. It uses an LLC half-bridge converter with DC-to-DC technology and Japanese main capacitors to maintain low ripple and stable voltages. The fully modular cable design and a 135 mm FDB fan provide flexible installation, reliable cooling and straightforward cable management for desktop systems.

Advantages

The PSU delivers 850 W of continuous power with a 20+4 pin ATX motherboard connector and wide input compatibility (100–240 V, 50/60 Hz). Japanese main capacitors and accurate voltage regulation reduce electrical noise and improve stability. The 135 mm fluid-dynamic bearing fan balances cooling performance and low noise, and fully modular cabling allows tidy builds and easy component changes. The unit is 80 PLUS Gold certified, meeting efficiency and environmental standards such as RoHS and CE.
