Platinum 1050

What is S³FC?

The industry’s first, Seasonic patented, advanced three-phased thermal control balances between silence and cooling. This Hybrid Silent Fan Control functions in three operational stages: Fanless Mode, Silent Mode, and Cooling Mode. In addition, there is a switch provided to allow for manual selection between the Seasonic S2FC (fan control without Fanless Mode) and the S3FC (fan control including Fanless Mode).

New! Power saving by hysteresis

Hysteresis is achieved by an additional fan control IC, which optimizes how frequently the fan switches on and off. At 25 °C ambient temperature the fan turns on when the load rises above 35 % (±5 %) and it turns off when the load drops below 25 % (±5 %). Due to this lag in response the fan switches on and off less frequently, which reduces noise and power loss in Fanless Mode and Silent Mode.

Dual Copper Bars

Due to their increased diameter, pure copper bars carry high current much more effectively than the traditional copper strips. If the goal is to achieve high quality power conversion with stable power output and minimized loss, it is very important that power conduction in the high wattage area remains extremely efficient, because it also reduces impedance and minimizes voltage drop as the load increases.

Sanyo Denki Fan

The world-renowned Sanyo Denki ball bearing fans are made of the highest quality components to ensure ultra-low noise performance. The fan’s perfect balance and even rotations are achieved via the use of spoon-shaped, high-density plastic fan blades that are finished off with smoothed leading edges. Sanyo Denki fans are known for their strict tolerance ball bearings and precision copper axels. Instead of the industry standard of two balancing points they use three points to strengthen the mount and further stabilize the blade.

Double Ball Bearing Fan

These durable power supply fans play an important part in the temperature control of the entire system by not only keeping themselves cool but also by removing warm air from inside the computer case. Coupled with Sea Sonic’s fan control circuit, double ball bearing fans are great performers, relatively quiet and have a very long life span.

80 PLUS^®Platinum

The higher the level of efficiency of the power supply, the less power gets wasted in the form of excess heat . The 80 PLUS^® Platinum certification guarantees greater than 90 %, 92 % and 89 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The Seasonic Platinum Series represents the highest level of technology and efficiency achievement of Sea Sonic during its 40 years of commitment to engineering excellence.

“Seasonic continues to hone their comprehensive product line with the introduction of two new Platinum Series power supplies. The enhancements made to the Platinum 1050 and Platinum 1200 translate to excellent performance, high efficiency and the ability to operate in silent-fanless mode at lower power levels. Throw in a 7-year warranty, a great assortment of all modular cables, really tight voltage regulation, clean DC outputs and you have two very good power supplies to consider for your next build or upgrade.”
