The X-Series 1050W power supply from Seasonic is a powerhouse - while also remaining highly efficient and quiet. Like all members of the X-Series line, the 120mm fan turns off at low power draw levels - and thanks to its 80PLUS Gold 90% efficient rating the fan is almost always going to be off when the computer idles or is just under basic usage. When more is required of it, though, the fan will kick on and keep the unit running cool - while providing enough power for even the most demanding hardware out there.
John D. (Senior Production Technician) Says:
The Seasonic 1050W X-Series power supply brings all the features we like about the 560W supply--fully modular design, idle fan at low temperatures, and Seasonic reliability--with a higher wattage rating. Highly recommended if the 560 or 850W versions don't meet your demands.

Features:
- Full Modular Design (DC to DC) Common to all X-Series power supplies, the new X-1050 and X-1250 feature the unique integrated DC connector panel with onboard VRM (Voltage Regulator Module) that enables not only near perfect D-to-D conversion with reduction of current loss / impedance and increase of efficiency but also a fully modular DC cabling that enables maximum flexibility of integration and forward compatibility.
- Seasonic Patented Hybrid Silent Fan Control-S2FC & S3FC An industry first, advanced 3 phased (Fanless, Silent and Cooling Mode) thermal control balances between silence and cooling. In addition, for X-1050 & 1250 a selector switch is provided to allow you to select between the Seasonic S2FC control, without fanless mode or the S3FC fan control, with fanless mode.
- Sanyo-Denki San Ace Silent Fan The world-renowned Sanyo Denki Ball bearing fans are made of the highest quality components to ensure maximum quality and performance. The use of spoon shaped high-density plastic fan blades with smoothed leading edges, strict tolerance ball bearings and precision copper axel are just some features to ensure ultra-low noise performance and quality. In addition, the fan uses 3 balancing points, instead of the industry standard of 2 points, to ensure perfect balance and rotation. The Sanyo Denki fan is a perfect match to the class leading Sea Sonic Hybrid Silent Fan control for the absolute top performance of the industry.
