550W SEASONIC FOCUS GOLD Series Power Supply
The FOCUS Gold power supplies are the ideal choice for people who do not want to break the bank, but stil want a solid power supplies with great reliability and efficiency. The semi-modular cabling design provides the most basic connections while allowing flexibility on the peripherals. The high quality 120mm FDB (Fluid Dynamic Bearing) fans are very quiet and proven to be very stable over the long run. The 120mm FDB fan inside is regulated by the Seasonic S2FC fan control, which optimizes the fan speed according to the needs of the system.
80 PLUS® Gold Design
Seasonic was the forerunner of creating the very first 80 PLUS® Gold certified power supply on the market and since that time it has built a very popular Gold series lineup that covers a full power range of power supplies with impeccable performance and efficiency. The 80 PLUS® Gold certification process tests and guarantees guarantees power efficiency above 87% @ 20% Load, 90% @ 50% Load and and 87% efficiency at 100 % operating loads, respectively. The clear advantage of buying a 80 PLUS® Gold Power Supply is the fact that the less energy gets wasted during power conversion, the lower the operating costs will be for the user.

Some cables are permanently attached to the power supply (most of the time the 24-pin and the 8-pin ATX power cables) and the rest of the cables can be used to connect the rest of the available components.
S2FC - Smart and Silent Fan Control
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.
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 FDBs Work
With Fluid Dynamic Bearing Fans, 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.
