The Chieftec Polaris power supply is of an advanced level, shows excellent efficiency (note: efficiency is not lower than 89% at peak load) and can easily distribute almost 100% of its rated power via the +12V line. They are built on the basis of heat-resistant Japanese capacitors and have the ability to use the main power line in multipolar or unipolar bus mode. Well, in stress tests, Polaris power supplies demonstrate an almost zero level of drawdown with an extremely low level of ripple.


Since its release in 2019, the original Polaris power supply has been in great demand among gamers. However, in 2023, the massive distribution of the ATX12V 3.0 specification significantly shook up the power supply market, forcing manufacturers to mass produce next-generation models for video cards with PCI-5.0 support. This is how the new Polaris 3.0 and Polaris PRO power supplies were born. Polaris 3.0 turned out to be the rightful successor to the original Polaris - it is a classic 80 Plus Gold power supply with modular cables, Japanese capacitors, a DC-DC half-bridge LLC converter and a wide choice of powers (850, 1050 and 1250 W). The package includes a 16-pin 12VHPWR cable required for connecting GeForce RTX 40 series video accelerators.

In turn, Polaris Pro is a flagship-level power supply with high-quality Japanese capacitors, half-bridge LLC circuit with DC-DC converters, 80 Plus Platinum energy efficiency certificate, detachable cables and an impressive power reserve of 1300 W. Like the regular Polaris 3.0, it complies with ATX 3.0 specifications and is equipped with a 12VHPWR power connector, so it does not require special adapters when connecting video cards with a 16-pin connector. When the overall system power consumption drops below 400W, the built-in 135mm fan can operate in silent mode.
