The very first full modular multi-output ATX, high-wattage power supply that has ever obtained the 80PLUS® Gold certification is introduced by Seasonic, this coveted power supply is named “X” and is initially offered in 750 watt versions to fulfill computer enthusiasts’ need for an ultimate power source.

Featuring a patent pending design of “DC Connector Module with Integrated VRM”, the X Series is set to achieve both near-perfect DC to DC conversion and fully modularized design without compromising efficiency. After a long wait, finally there is a product that delivers the complete package, ultra-high efficiency, greatly improved dynamic response, and customizable cable arrangement that is tailored to meet any individual’s needs.

As a leading provider of silent power supply, Seasonic this time around delivers a true breakthrough solution for thermal and noise management. The X Series adopts a clever “Hybrid Silent Fan Control” design, which offers three distinct operation modes, fanless mode, silent mode, and cooling mode. The X automatically adjusts fan mode and speed according to the ambient temperature level. This brand new design not only optimizes heat dissipation, but also prolongs lifespan of the system by reducing unnecessary fan rotation. To make the X Series even more robust and exciting, Seasonic offers Sanyo Denki San Ace PWM Silent Fan on X, the best fan there is in the industry and taking advantage of the PWM feature.

The X Series represents the 'Green PC technology' that helps computer users
to save in electricity bill at all times. It achieves the 80PLUS® Gold standard
that guarantees an above 87% efficiency rating across 20%, 50% and 100%
loading along with a true power factor of >0.9. Moreover, the X series is
compliant with Energy Star 5.0 and reduces energy consumption under
standby, sleep and idle modes. To find out more about 80 PLUS, click here.(
