Seasonic engineers have created a brand new product line based on advanced
technology emanating from many years of intensive active research. The result of
this development is the solid FOCUS+ Series, which implements modern design and
shows outstanding electrical performance. This power supply is small and
entirely modular, which will be hard to resist. It is available in 80 PLUS®
Platinum and Gold efficiency ratings.
80 PLUS® Platinum
The FOCUS PLUS Platinum Series achieves 80 PLUS® Platinum certification with
its 92 % efficiency at 50 % system load.
Cable-free Connection Design
Seasonic’s engineers have implemented a new design feature, where instead of
cables; the back panel and the PCB (Printed Circuit Board) are connected by a
copper plate. This breakthrough solution not only lowers the chance of
production errors during manual insertion but it also improves output power
quality.
Hybrid Silent fan Control
The industry’s first, Seasonic patented, advanced three-phased thermal
control achieves optimal between silence and cooling. This Hybrid Silent Fan
Control functions in three operational stages: Fanless Mode, Silent Mode, and
Cooling Mode.
Benefits
- Reduced noise without increase in temperature;
- Extended fan life due to the reduced number of fan rotations;
- Optimized heat dissipation at all times;
- Unsurpassed silent performance in Fanless Mode.
Additionally, there is a switch at the back of the power supply which allows
users to customize their cooling needs by selecting between the Seasonic S2FC
(fan control without Fanless Mode) and the S3FC (fan control including Fanless
Mode).
The Fan Control Button
The fan control button can be found on the back of the back of the FOCUS PLUS
power supply, next to the power switch. The image here illustrates how to select
different fan control modes to suit your need.
DO NOT press the button if you wish to include the Fanless Mode, which means
the fan in the power supply will not spin when the power supply is under light
loads. Press the button if you wish to have the fan spin at all times, even at
lower loads.
Fluid Dynamic Fan Bearing
High performance Fluid Dynamic Bearing (FDB) fans are designed to take
advantage of the impact absorbance effects of oil. They are extremely reliable
and generate considerably less operating noise and heat than ball bearing fans.
The lubrication of the bearing surface reduces friction and vibration and
therefore lowers overall power consumption. Due to the effortless, quieter
rotations and its robust construction, this reliable fan technology also greatly
increases the lifespan of the fan.
How it works
When the fan shaft rotates, high pressure oil drifts along the grooves of the
bearing sleeve to generate a thin layer of lubrication between the bearing
faces. As the speed increases, so does dynamic oil pressure and the shaft is
lifted from the bearing to create smooth, effortless rotations. The herringbone
shape of the groves helps to efficiently channel the lubricant and avert
leakage.
