Chieftec Polaris PPS-750FC

A powerful and highly efficient computer power supply unit of the ATX 12V v2.4 standard with modern circuitry and high-quality components. It is a mid-range model from the Chieftec Polaris family, released in 2019, whose products can deliver power from 550 to 1250 W. It is capable of powering a PC consuming up to 750 W. Designed for operation in a wide range of input voltages (from 100 to 240 W), making it insensitive to spontaneous fluctuations in the electrical network parameters.

The manufacturer positions it as a mid-range priced product intended for powering high-performance gaming systems with high-end/upper-mid-range video cards (TDP up to 350 W). It is suitable as a power source for powerful mid/high-level workstations, including AMD Ryzen Threadripper (Socket TR4) and Intel Xeon (Socket LGA3647) HEDT platforms. The high stability of the Chieftec Polaris PPS-750FC power supply unit's output voltages is ensured by its advanced circuitry (a resonant converter in the high-voltage section, synchronous rectifier, and DC/DC converters in the low-voltage section). This configuration allows delivering up to 99% of the rated power on the +12V rail, providing a current up to 62.5A. Importantly, the efficiency at 50% load reaches an impressive 92%, matching the 80 Plus Gold level. For effective cooling, a controlled 7-blade 120 mm fan is provided.
