Chieftec Polaris 3.0 PPS-850FC-A3

Powerful and highly efficient ATX computer power supply with state-of-the-art circuit design, high-efficiency half-bridge circuitry with DC-DC converters, fully modular cables, a complete list of protections and state-of-the-art circuit design. It is an update of the original 2019 Chieftec Polaris model, the key feature of which is a 16-pin connector for efficient power supply of current and next generation video cards with support for the PCI-E 5.0 bus.

Capable of powering a PC that consumes up to 850 watts. The manufacturer is positioning it as a mid-price product designed to power high-performance gaming systems with top/pre-top models of video cards a la RTX 4060/4070/4080/4090. The package includes a 12VHPWR cable for GeForce RTX 40 series video accelerators. High stability of output voltages is ensured by advanced circuit design, which includes an LLC half-bridge converter with DC-DC technology, Japanese main capacitors to achieve low ripple and tight voltage regulation.

This arrangement allows up to 99% of the rated power to be delivered via the +12V line and provides a current of up to 70.8A. Importantly, the efficiency at 50% load reaches an impressive 92%, which corresponds to the 80 Plus Gold level. The silent 135mm fan uses a fluid dynamic bearing to optimize the balance between efficient cooling and noise levels. Fully modular cable management allows for clean, easy assembly within any system. A wide range of protective systems of this power supply will allow the PC owner not to worry about the quality of the power supply to the system unit.
