Chieftec Atmos CPX-850FC

A high-performance computer power supply from Chieftec with a power reserve of 850 W, support for the ATX 3.0 power standard and high efficiency of energy distribution (80+ Gold standard, 90% efficiency). The model is part of a relatively new line of Atmos power supplies and is positioned as a modern and highly reliable solution for gaming PCs and workstations equipped with powerful video cards from Radeon and NVIDIA with support for the PCI-E 5.0 power standard.

The design uses Japanese Nippon Chemi-Con capacitors, which ensure a long service life and high reliability of the device. The main power supply circuit is built on an SRC Full-bridge converter using DC-to-DC technology, which allows for the most efficient distribution of the load. Active PFC and a semi-passive cooling system provide an optimal level of power consumption and stable operation under any load, from moderate to peak.

The IN1S429I-DCG protection chip is responsible for the safety of the power supply, providing protection against overvoltage, excess current and short circuit. According to the manufacturer, the 120 mm Hong Hua fan with a hydrodynamic bearing guarantees low noise levels and a long service life at all load levels. When power consumption is below 200 W, the power supply switches to ECO mode, turning off the fan to reduce noise. The official manufacturer's warranty is 5 years.
