Due to its small form factor the Focus+ Gold 550 watt power supply is a great solution for those, who want to build smaller systems and care about the airy arrangement inside their computer case. The fully modular flat black cables are easy to install, save space inside the computer case and provide ample customization and upgrading possibilities at the same time. This mid power range power supply is not only small, but mean too. It boasts the highest power density in its class and it also has remarkable stability and output characteristics during operation.

Compact Size
This ultra-high power density, small footprint (140 mm depth) power supply is an ideal choice for all, especially compact ATX cases.

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.

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 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
Seasonic’s advanced design is to improve load regulation which reduces voltage variations to provide smooth and stable operations.

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.

10 Years Warranty
Our commitment to superior Seasonic quality.
