The Cyonic AU-450x is designed to be the heart of a moderate gaming system or a powerful home theater PC, where silence and steady performance are paramount. The AU-450x runs quietly and efficiently. The built in fluid dynamic bearing fan integrated with the Cyonic Smart Fan Control System promises inaudible fan noise. The 80PLUS® Gold efficiency maximizes the effect of the silent fan and the thermal control to a greater extend. At 50 % system load, the AU-450x can achieve up to 90 % efficiency, wasting little energy when converting AC to DC. The 140 mm depth chassis will be the perfect fit in your compact system, whose internal organization can be further controlled with the black, ribbon shaped, fully modular cables.

80 Plus Gold

80 PLUS® Gold Certified

The 80 PLUS® Gold certification guarantees greater than 87%, 90%, and 87% efficiency at 20%, 50% and 100% operating loads, respectively.

Fully Modular Cable

Fully Modular Cable Design

Fully customizable cables not only simplify the installation process but also reduce the clutter inside the computer case. Reduced number of components allow for better ventilation and enhanced cooling.

FDB fan

FDB (Fluid Dynamic Fan Bearing) – 120 mm

It greatly reduces fan noise during operation. As there is less friction inside, the fan will have a longer life.

Gold Coated Connector

Gold Coated Connector Contacts

The connectors do not tarnish over time and increase the efficiency of current transmission.

Compact ATX Size

Compact ATX Size

The power supply is only 140 mm in depth, which makes it an excellent choice for smaller sized cases.

105 °C Japanese Electrolytic Capacitors

105 °C Japanese Electrolytic Capacitors

Premium quality Japanese capacitors with 105 °C rating increase reliability and extend product life.

DC to DC Converter Design

DC to DC Converter Design
