Seasonic M12II EVO 520W Modular Power Supply

M12II EVO

The M12II EVO series is an upgraded Seasonic product family that supports Intel’s fourth generation of core processors and provides reliable performance for enthusiast seeking 80 PLUS Bronze efficiency. The main features of the M12II EVO series units at a glance are fully modular flat black cables, highly reliable 105°C aluminum electrolytic capacitors, Smart and Silent Fan Control technology (S2FC), ample +12 V output and Seasonic’s 5-year worldwide manufacturer’s warranty.

80 PLUS® Bronze

The 80 PLUS® Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill. The 80 PLUS® Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. Sea Sonic’s Bronze Series is an economical choice with great performance and high built-in value.

Fully Modular Cables

In Sea Sonic’s patented design feature full modularity comes hand-in-hand with the extensive use of SMD technology to increase the overall performance and reliability of this power supply. The simple and inventive layout scheme helps to attain unsurpassed quality and performance, where efficiency is further enhanced by minimized line resistance, reduced voltage drop and lower impedance. Reduced component count and better space utilization facilitate optimal air flow inside the case and promote heat dissipation, proper cooling and ultimately longer product life.

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 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.
