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.
The New Seasonic S3FC Fan control
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.
No Negative Voltage Tolerance
Intel guidelines specify that the DC output voltages have to remain within the regulation range of +/- 5 %. However, power supply testers and reviewers prefer to have this allowance down to +/- 3 %. Seasonic has implemented and even stricter voltage regulation which entirely eliminates negative deviations and keeps voltage 80% tighter than Intel specifications and 66 % tighter than top reviewers recommend. The result of clean output power is quicker CPU response and a better overclocking performance.
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.
