M12II-850 EVO

The quiet operation of this newly enhanced unit is clearly one of its advantages. It is equipped with a fluid dynamic bearing fan and a matching high performance fan control that is set to regulate the rotation of the fan to achieve the most desirable balance between silence and the necessity of cooling. The fully modular flat black cables are neat and easily organized, leaving more room for proper cooling inside the computer case. Durable components, clean power and all the essential functions that enthusiastic gamers require will make this choice hard to resist.

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.

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.

Fluid Dyanamic 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:

Solid Capacitor

Highly rated capacitors ensure long-term stability and reliability even under extreme conditions.

Universal AC Input

Switch-mode power supplies can tolerate a wide range of power frequencies and voltages. The power supply is designed to automatically adjust to the inpout AC voltage, therefore it can safely be used anywhere in the world.
