The very first full modular multi-output ATX, high-wattage power supply that has ever obtained the 80PLUS Gold certification is introduced by Sea Sonic. This coveted power supply is named “X” and is offered in a 750 watt version to fulfill computer enthusiasts’ need for the ultimate power source.
Featuring a 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. There's finally 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 supplies, Sea Sonic 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 the lifespan of the system by reducing unnecessary fan rotation. To make the X Series even more robust and exciting, Sea Sonic offers a Sanyo Denki San Ace PWM Silent Fan, the best fan there is in the industry, and takes advantage of the PWM feature.
