Features

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.

S2FC

• 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 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:

Tight Voltage Regulation

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

DC to DC Converter Design

• The step down DC to DC converter design allows the power supply to be able to serve system components with various voltage needs. Not only is it a flexible, clean voltage conversion solution but it also maximizes the 12 V DC rail output, delivers superior dynamic response and , ultimately, provides for greater system stability.

105 °C Japanese Capacitor

• Premium quality Japanese capacitors with 105 °C rating increase overall reliability and extend product life.

Modular Cable Design

• 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.
