Seasonic Focus Plus 550 Gold
Overview
If you are looking for your next compact system build ideas, the FOCUS+Gold
550 watt power supplies may be the ideal choice for you with their reliable and
efficient power delivery, fully modular cables and efficiently regulated quiet
operation. The high quality 120 mm Fluid Dynamic Bearing (FDB) fans are very
quiet and proven to be very stable over the long run. When you couple these
great FDB fans with Seasonics own Hybrid Silent Fan Control, then you have a
power supply that outputs the least possible sound levels during operation.
80 PLUSPlatinum
The higher the level of efficiency of the power supply, the less power gets
wasted in the form of excess heat . The 80 PLUSPlatinum
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.
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.
The
following illustration depicts the main characteristics of the FDB fans:
Hybrid Silent fan Control
The industrys 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 of this design
- 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).
Tight
Voltage Regulation
Seasonics advanced design is to improve load regulation which reduces
voltage variations to provide smooth and stable operations.
Cable-free Connection Design
Seasonics 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.
