FOCUS Plus 650 Gold

Due to its small form factor the Focus+ Gold 650 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.

80 PLUS®Gold

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 highly efficient 80 PLUS® Gold certification guarantees greater than 87 %, 90 % and 87 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. The clear advantage of buying a power supply with 80 PLUS® Gold rating is the fact that the less energy gets wasted during power conversion, the lower the operating costs will be for the user.


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.
The following illustration depicts the main characteristics of the FDB fans:

Fan Control S3FC-01

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.

S3FC

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).

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.

Tight Voltage Regulation-01

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.
