Chieftec Polaris 3.0 1050W virtalähde 20+4 Pin ATX ATX musta

The CHIEFTEC Polaris 3.0 1050W power supply unit complies with Intel ATX 3.0 and delivers up to 1050 W of continuous power. Designed for modern PCs, it supports PCIe Gen5 and carries 80 PLUS Gold certification for high energy efficiency. The PSU uses an LLC half-bridge converter with DC-to-DC technology and Japanese main capacitors to maintain low ripple and stable voltage. A fully modular cable system and a 135 mm FDB silent fan enable neat cable routing and effective cooling while minimizing noise.

Advantages

The unit combines ATX 3.0 compatibility and PCIe Gen5 support with 80 PLUS Gold efficiency to provide reliable power for high-performance systems. Advanced topology with LLC half-bridge and DC-to-DC stages together with Japanese capacitors improves voltage regulation and reduces ripple. The 135 mm fluid-dynamic bearing fan balances cooling performance and long-term durability. Fully modular cables simplify installation and maintenance and support clean system builds.

How to use

Install the PSU into a compatible ATX 3.0 chassis and connect the 20+4 pin ATX cable to the motherboard. Attach the required modular cables for CPU, GPU, SATA and peripherals according to your component layout. Ensure the AC input matches the local mains (100–240 V, 50/60 Hz) and secure the unit with the supplied screws. Power on the system and verify correct voltage rails and stable operation before performing sustained high-load tasks.

Recommendations

For optimal performance, pair the Chieftec Polaris 3.0 1050W with components that benefit from ATX 3.0 and PCIe Gen5 features. Maintain adequate case airflow, keep the fan and ventilation free of dust, and use only the supplied modular cables to preserve electrical reliability and warranty coverage.
