The Focus series from Seasonic represents a long-awaited re-entry into the power supply market and includes compact 80 PLUS Gold-rated models with fully modular cable management that also looks stylish while operating quietly thanks to the quiet and reliable semi-passive 120 mm fan. The smart choice of components, included so as to complement one another during operation, as well as the materials used all meet the high standards of Seasonic and the end result is a premium product with a 10 year guarantee that demonstrates Seasonic's confidence in their power supplies.
The Seasonic Focus GX Gold Power Supply at a Glance:
- 550 Watt power supply with powerful 45A single rail
- High efficiency with 80 PLUS Gold certification
- Quiet 120 mm fan with semi-passive mode
- Fully modular cable management with flat cables
- Four 6+2-pin PCIe connectors for graphics cards
Power Supply with 80 PLUS Gold Efficiency and Powerful 62A Single Rail
The Seasonic Focus GX Gold supplies up to 550 Watts in total output, meaning that even high-end PCs will be powered with ease. The powerful 12 Volt rail also delivers a full 45A output. In spite of these impressive specifications, the Seasonic Focus PX Platinum is created with efficiency in mind as well, and this could only happen when Seasonic opts for the highest quality components - such as the capacitors for example. Consequently, the power supply received an 80 PLUS Platinum certification, meaning that it is capable of 90% efficiency under a 50% load.
In terms of tidiness, Seasonic smartly opted to make their power supply cables fully modular - arguably a must with the amount of connectivity options on offer! Besides a 24-Pin- and two 4+4-pin cables, the PSU includes (among other things), four 6+2-pin PCIe connectors as well as eight SATA- and three 4-pin Molex connectors. The cables are very flat and easy to cable manage.
The included 120 mm fan provides, thanks in large part to its quiet-running Fluid Dynamic Bearings, very low noise during operation. The added benefit of FDB is the fact that they also happen to be incredibly robust and durable. A switch on the back of the power supply allows users to choose between automatic fan regulation either with or without a passive mode. Depending on how hard the power supply is being pushed, users will benefit from reduced noise levels or maximised cooling performance respectively.
It almost goes without saying that the Seasonic Focus PX Platinum naturally includes all the safety features we have come to expect from modern power supplies. Should the PSU fail unexpectedly, not to worry - Seasonic stands behind this exceptional product with a full ten-year manufacturer's guarantee!
Focus Plus Gold
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 Gold
The FOCUS PLUS Gold Series achieves 80 PLUS® Gold certification with its 90 % 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.
- 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 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.
